In the process of iron and steel smelting, if the carbon content in the molten iron is not improved well, it will affect the quality of the steel and increase the cost of smelting and casting. In order to ensure the quality of steel casting, the quality of smelting can be improved by increasing the amount of smelted pig iron, but the raw iron of pig iron is relatively high. When using a recarburizer, it is not necessary to put too much pig iron. It is possible to increase the carbon content in the molten iron.
At present, there are many materials for cast iron recarburizers on the market. In general, coal quality recarburizers, petroleum coke recarburizers, calcined petroleum cokes, graphitized petroleum coke recarburizers and artificial graphite can be used as cast iron smelting. Recarburizer used. Although these products can be used as recarburizers, you must choose the right recarburizer when you buy them. If the quality of the products to be cast is high, you need to choose artificial graphitized petroleum coke recarburizer.
If the quality of the smelting metal is not high, you can choose a lower cost recarburizer. For example, in converter smelting, when high carbon steel is used, you can use petroleum coke with a lot of impurities as a recarburizer. However, the requirements for the recarburizer for the top-blown converter steelmaking are higher than the carbon of the fixed furnace recarburizer. The ash, volatiles, sulfur, phosphorus, nitrogen and other impurities are also required to be high in content, and are required to be dry, clean, and granular. Moderately, it is necessary to choose a calcined coke recarburizer and a graphitized recarburizer.
Among them, the most used mainstream carbonizers specifications are: fixed carbon C ≥ 98%, volatile matter ≤ 1.0%, sulfur content ≤ 1%, moisture ≤ 0.5%, particle size is more than 1-5mm, this recarburizer The indicator shows the calcined petroleum coke recarburizer, which is calcined petroleum coke. In the past, in the domestic smelting industry, relatively low-end non-graphitizing recarburizers were generally used. With the improvement of product quality and upgrading, more and more enterprises using graphitized petroleum coke in China will increase carbonization of graphitized petroleum coke. The indicators of the agent are: fixed carbon C ≥ 98.5%, volatile matter ≤ 0.5%, sulfur content ≤ 0.1%, moisture ≤ 0.5%, particle size between 0-5mm.
Different types of recarburizers are used differently. In the process of selecting a recarburizing agent for steel making, the particle size should be moderate, the particle size is too fine to be easily burned, and when it is too coarse to be added, it floats on the surface of the molten steel and is not easily absorbed by the molten steel. With the development of the market, the quality requirements of steelmaking refining agents are getting higher and higher, especially the conversion from coal quality carbonizers to calcined petroleum coke recarburizers, or graphitized petroleum coke recarburizers. .
The recarburizer is a material used to increase the carbon content. The main component is carbon. There are many materials that can be used as a recarburizer. Commonly used are coke and anthracite, calcined petroleum coke, graphitized petroleum coke, and graphite (artificial graphite). , natural graphite) and mixtures made from such materials.
1. Coke and anthracite
Coke is a type of solid fuel. It is obtained by dry distillation of coal under high temperature conditions of about 1000 °C. The main component is fixed carbon, followed by ash, and contains less volatile matter and sulfur. Silver-gray, metallic luster. Hard and porous. In addition to a large amount of coke and iron non-ferrous metal smelting (metallurgical coke), coke is also used in foundry, chemical, calcium carbide and ferroalloys, and its quality requirements are different. For example, for casting coke, it is generally required to have large particle size, low porosity, high fixed carbon and low sulfur content; coking for chemical gasification is not strict with strength, but requires good reactivity, high ash melting point, and coke requirement for calcium carbide production. Try to increase the fixed carbon content.
Anthracite is a hard, dense and high-gloss coal mine. The main applications of anthracite lump coal are chemical fertilizer (nitrogen fertilizer, synthetic ammonia), ceramics, manufacturing forging and other industries; anthracite coal is mainly used in the metallurgical industry for blast furnace injection (blast furnace coal mainly includes anthracite, lean coal, lean coal and gas coal) ).
2. Calcined petroleum coke (calcined coke or calcined coke)
Calcined petroleum coke is a widely used recarburizer, which is obtained by calcining petroleum coke. Petroleum coke is a by-product of refined crude oil. Residual oil and petroleum asphalt obtained by vacuum distillation or vacuum distillation can be used as raw materials for petroleum coke, and then coke is obtained to obtain raw petroleum coke. The annual production of American petroleum coke is about 30 million T. The raw petroleum coke has high impurity content and cannot be directly used as a recarburizer. It must be calcined first.
Raw petroleum coke has spongy, needle-like, granular and fluid states.
Sponge petroleum coke is produced by delayed coking. Because of its high sulfur and metal content, it is usually used as a fuel for calcination and as a raw material for calcined petroleum coke. The calcined plum cotton coke is mainly used in the aluminum industry and as a recarburizer.
The acicular petroleum coke is obtained by a delayed coking process using a raw material having a high content of aromatic hydrocarbons and a low impurity content. This coke has a needle-like structure that is easily broken, sometimes referred to as graphite coke, and is mainly used for the manufacture of graphite electrodes after calcination.
Granular petroleum coke is a hard granule. It is a raw material with a high content of sulfur and bitumen. It is produced by delayed coking and is mainly used as a fuel.
The fluid petroleum coke is obtained by continuous coking in a fluidized bed. It is in the form of fine particles, has no directional structure, high sulfur content and low volatile content.
The burning of petroleum coke is to remove sulfur, moisture, and volatiles. The raw petroleum coke is burned at 1200 ° C - 1350 t ° C to make it substantially pure carbon.
The largest user of smoked petroleum coke is the aluminum industry, 7 which is used to make anodes for the reduction of bauxite. The United States produces smoked petroleum coke, which accounts for about 6% of cast iron enhancers.
3. Graphitized petroleum coke
Graphitized petroleum coke refers to the high-temperature graphitization of petroleum coke. Under the high temperature of 3000 °C, the carbon molecular form in the petroleum coke is changed from an irregular arrangement to a hexagonal uniform arrangement. The agent is most easily decomposed in molten iron.
Characteristics of graphitized recarburizer
1) The low-sulfur graphitization recarburizer has a high decomposition rate and a high absorption rate, and can reach more than 90%.
2) High carbon, low sulfur, low nitrogen, and extremely harmful components.
3) Adding graphite nucleus to molten steel and molten iron, more uniform and finer distribution in molten steel and molten iron, so that the performance is more excellent and stable.
4. Graphite is an allotrope of elemental carbon. Each carbon atom is connected with three other carbon atoms (multiple hexagons arranged in a honeycomb shape) to form a covalent molecule by covalent bonding. . Graphite and carbon products have excellent performance, are increasingly used, and the production capacity and benefits are growing rapidly. There are more enterprises of graphite and carbon products above the scale of China, and the concentration is low. With the rapid development of China's metallurgy, chemical, machinery, medical equipment, nuclear power, automotive, aerospace and other industries, the demand for graphite and carbon products will continue to grow in these industries, and China's graphite and carbon products industry will maintain rapid growth. . Graphite is mainly divided into natural graphite and artificial graphite.
4.1. Natural graphite
Natural graphite can be divided into two types: flake graphite and microcrystalline graphite. Microcrystalline graphite has a high ash content and is generally not used as a carbon reinforcer for cast iron. There are many varieties of flake graphite. High-carbon flake graphite needs to be extracted by chemical methods, or heated to high temperature to decompose and volatilize the oxides. This flake graphite has low yield and high price, and generally does not act as a recarburizer; low carbon scales Graphite has a high ash content and should not be used as a recarburizer; it is mainly used as a carbon reinforcer for medium carbon graphite, but it is not used in large amounts.
4.2. Artificial graphite
Among the above various recarburizing agents, the best quality is artificial graphite. The main raw material for the manufacture of artificial graphite is powdered high-quality simmered petroleum coke, in which asphalt is added as a binder, and a small amount of other auxiliary materials are added. After the various raw materials are combined, they are press-formed and then treated in a non-oxidizing atmosphere at 2500 to 3000 ° C to be graphitized. After high temperature treatment, the ash, sulfur and gas contents are greatly reduced. Due to the high price of artificial graphite products, the artificial graphite breakers commonly used in foundries are mostly cut when manufacturing graphite electrodes.
Recycled materials such as chips, used electrodes and graphite blocks to reduce production costs. In the smelting of ductile iron, in order to make the metallurgical quality of cast iron superior, the carbon-reducing agent should be the first choice of artificial graphite. For this reason, it is better to purchase scrap electrodes from nearby companies that use electric arc furnace steelmaking or electrolytic aluminum production enterprises, and crush them to the required particle size. .
180909 This week, China's recarburizer market started to work stably and trading was good. Among them, the market price of recalcurizer (common calcined coal) is lower. The main reason is that the downstream steel mills are affected by many factors such as environmental protection and trade warfare. In general, recarburizer shipments are limited, and the company is basically stable in environmental protection. Most of the inventory, the market price will decline. The market price of calcined coke recarburizer (calcined petroleum coke) was stable overall. The company said that although the price is high, the supply and demand side is relatively balanced, and the market is stable; the graphitized rebcarburizer (graphitized petroleum coke) market is raised by individual companies, and the market is out. The goods are in good condition and the production situation of the company is relatively stable.
Calcined coal recarburizer:
This week, the mainstream price of China's general calcined coal rebcarurizer market was lowered. The production in the main producing area of Ningxia is stable overall, affected by the rain, and the transportation is slightly limited. The enterprises are mostly in the process of rectification and maintenance, preparing for the acceptance at the end of September. Due to the downstream receiving, the enterprises are more or less in stock, the market In general, the overall transaction is relatively light, and the mainstream market price is down. The overall market production in North China is relatively stable, but environmental protection pressure is still not small. The overall performance of the market is generally high, mainly depending on the poor start of the downstream steel mills.
This week, the mainstream price of the calcined coke recarburizer market remained stable and the market was stable. In the northeast and north China, the production of enterprises is stable, the price of calcined coke is rising, and the cost pressure of enterprises is increasing. However, in view of the high price in the downstream market, the price intention is weak, the production enterprises are still shipping, and the mainstream prices of the market have not yet fully fluctuated.
Graphitized petroleum coke recarburizer:
This week, the market price of China's graphitized petroleum coke recarburizer was stable, and the company's price intention was strong. The main reason was the increase in cost. The crude oil price of raw materials rose in the mainstream, and the high-end operation, individual companies raised product prices. Among them, the production of individual enterprises in Henan and Xinjiang was suspended due to environmental protection, and the operating rate fell. In addition, the graphitization enterprises of anode materials in the market will start construction in the second half of the year, and the output will be released. Graphitized rebcarurizer is highly concentrated in the Inner Mongolia region. Enterprises in Jiangsu Province have normal production, good shipments and smooth exports.
Recarburizer is mainly used in steel smelting process. Due to improper ingredients or improper loading and excessive decarburization, the carbon content in steel or iron sometimes fails to meet the expected requirements. At this time, carbon is added to steel or molten iron. The relationship between recarburizer and steel is also very close. Domestic steel prices have stabilized this week. Recently, the market turnover is weak, but the recent environmental protection inspection work in Shandong is in full swing. The inventory of various steel mills has decreased, and the market price support is strong. Steel mills have obvious willingness to price, and the market price on the weekend has also risen slightly, but the mainstream temporary stability has been comprehensively considered. It is expected that the short building materials market will be operated in a multi-country volatility with a range of 50 yuan/ton.
Forecast of the market outlook: the raw material price of raw calcined coal will rebound in September due to the limited price of environmental protection acceptance enterprises, and the price of the crude calcined recarburizer will develop in a stable-up mode. The price of the calcined recarburizer and the graphitized petroleum coke recarburizer is driven by cost, and the price is stable or slightly upward.
The use of recarburizers, as the name implies, is to increase the content of carbon. Its main purpose is to increase the carbon content lost during the steelmaking process. If the carbon content does not meet the expected requirements during the steelmaking process, a certain proportion is required. The recarburizer enhances the carbon content of the molten steel and smelts the ideal steel.
There are many kinds of raw materials for recarburizers, and the production process is also different. There are wood carbons, coal carbons, petroleum cokes, etc., while petroleum cokes are divided into calcined coke recarburizers and graphitized recarburizers. The current mainstream recarburizer.
The calcined petroleum coke recarburizer refers to the calcination of the raw material petroleum coke, and the temperature is controlled at 1250～1380°C. During the calcination process, the structure and element composition of the petroleum coke undergo a series of deep changes, thereby improving their physics. Chemical properties.
Why is petroleum coke calcined?
The purpose of calcination:
1. Eliminate volatiles and moisture in petroleum coke raw materials. After calcination, the volatile matter is 0.5% or less, and the water content is 0.3% or less.
The calcined volatiles and moisture represent the degree of calcination, which does not require secondary shrinkage and crack formation during calcination.
2. Improve the density and mechanical strength of petroleum coke raw materials. The true density is 2.00 g/cm3 or more.
The true density of the calcined coke affects the true density of the final product, and the mechanical strength is low. The bulk density is low, which affects the molding. The main performance is difficult to form. The height of the green block does not meet the requirements within the required time, which affects the operation of the aluminum electrolytic cell.
3. Improve the electrical conductivity of petroleum coke raw materials.
The calcined coke specific resistance affects the final product resistivity.
4. Improve the chemical stability of petroleum coke raw materials. Improved oxidation resistance.
Graphitized petroleum coke recarburizer is a process of treating petroleum coke into high temperature by graphite. This process is the process of energizing petroleum coke and then calcining at a high temperature of 3000 degrees, so that the carbon molecular form of petroleum coke is changed from irregular arrangement to hexagonal uniformity. In the way of arrangement, petroleum coke in this way can be better decomposed in molten iron to improve the effect of carbon absorption. Graphitized petroleum coke is the best refining agent for smelting. In the steelmaking industry, to produce good steel, there must be good raw materials, including good recarburizers, and graphitized petroleum coke is the best recarburizer. In the absence of graphitized petroleum coke, the graphite electrode has less scrap and higher price, which not only increases the cost of steelmaking, but also restricts the development of the steel industry. The appearance of graphitized petroleum coke breaks this bottleneck.
How much is a ton of recarburizer? The price of recarburizer depends on the specific indicators and particle size, such as the amount of fixed carbon, the amount of sulfur, the size of the grain, etc., in order to report the exact price, as well as the source of goods and freight, etc., Foshan Jitian Foundry Co., Ltd. mainly supplies calcined After the coke recarburizer and graphitization recarburizer, for Guangdong, Hunan, Guangxi, Jiangxi, Fujian and other provinces, customers are welcome to contact 2018 the most new carbon agent price, indicators and granularity!

The emergence of Graphitized Petroleum Coke is a matter of recent years. Although it is not a new product, it belongs to one of the existing graphite materials. Because of its simple survival method and low cost of survival, it has developed a new use.
First, Graphitized Petroleum Coke is the best carbon carburizing agent for smelting. In the steel making industry, good raw materials, including good carburizing agents, must be available for the production of steel, and Graphitized Petroleum Coke is the best carburizing agent. In the absence of graphite fossil oil coke, the cost of the graphite electrode is relatively small and the price is high, which not only increases the cost of steelmaking, but also restricts the development of steel industry. The emergence of Graphitized Petroleum Coke breaks the bottleneck.
China's steel industry is developing rapidly. The output of steel is already the first in the world. In 2011, the output of steel in China was 6.83 million tons and 7.13 million tons in 2012. In the past, in the domestic smelting industry, the low end non Graphitized Petroleum Coke is generally used. With the need of product quality improvement and upgrading, more and more graphite coke will be used in China. Conservative calculation of smelting steel according to 0.05% graphitization coke, the annual dosage is 350 thousand tons.
In recent years, the demand for energy saving and emission reduction is getting higher and higher, and industrial furnaces are developing towards large scale, super large scale and science and technology. Therefore, the performance requirements of large cathode block, large carbon electrode, graphitized electrode and electrode paste for its supporting service are becoming higher and higher. Making large cathode blocks, large carbon electrodes and graphitized electrodes and electrode paste will add more performance graphite (the by-product of graphite electrode).
Graphitized Petroleum Coke can partly replace graphite crushing, and the market demand increases year by year. The cumulative production of graphite and carbon products in China in the 1-12 month of 2012 was 28 million 668 thousand tons, of which 2 million 860 thousand tons of graphite and coke coke were added to the production of graphite and carbon products on an average of 10%. In 2012, the output of graphite electrode produced by graphite in China was 648 thousand tons, and 7% of graphite broken was 45 thousand and 360 tons. The amount of graphite broken is small, the cost is high, the price is high. Therefore, graphite fossil oil coke has good business prospects.
Carbon and graphite production should be used in the fields of military industrial pyrotechnics material stabilizer, light industry pencil core, electric industry carbon brush, electrode of battery industry and catalyst additive in chemical fertilizer industry. Through deep processing, graphitized coke can obtain high purity graphite, lithium ion battery negative electrode material, graphite milk, graphite seal material and composite material, graphite wear additive, graphene and other high-tech products. In conclusion, graphitized petroleum Jiaozuo is the raw material. It has broad uses and prospects.
