A ductile iron pipe is a type of cast iron that is an alloy of iron, carbon and silicon. Graphite in ductile iron exists in the form of spheres, so the mechanical properties of the material itself are better improved, with the nature of iron and the properties of steel.

Development history of ductile iron
In 1948, A. P. Ganganebin et al. pointed out that magnesium was added to cast iron, followed by ferrosilicon as an inoculant. When the residual magnesium amount was more than 0.04 wt%, spheroidal graphite was obtained. Since then, ductile iron has begun large-scale industrial production.

Development and current status of Chinese ductile iron pipe
The industry of ductile iron pipes in China started in the early 1990s with the strong support of the China Urban Water Supply Association. After nearly 20 years of practical use, its safety and practicability have been widely recognized by the water supply industry. The annual output has reached 2.2 million tons, 11 times that of 1990. Since China is a country with a lack of water resources, there are more than 600 water-scarce cities and more than 200 water-scarce cities. The water supply and water-saving business is in the ascendant, and ductile iron pipes have broad prospects for development.

Ductile iron pipe is a kind of cast iron pipe. The ductile iron pipe is mainly called centrifugal ductile iron pipe. It has the essence of iron, the performance of steel, excellent anti-corrosion performance, good ductility, good sealing effect, easy installation, mainly used for Municipalities, industrial and mining enterprises for water supply, gas transmission, oil transportation, etc., the quality requirements of the cast iron pipe spheroidization level control is 1-3 (spheroidization rate) 80%.

The recarburizer required for the smelting cast iron in the smelting process is usually a graphite recarburizer. According to the requirements of carbon and sulfur content, different carbon and sulfur content recarburizers are selected. The graphite recarburizer sulfur content provided by Foshan Jitian Foundry Co., Ltd. There are 0.3% and 0.05%, the specific indicators are as follows:

Semi-graphite petroleum coke recarburizer:

In the transmission and distribution of drinking water, ductile iron pipes have achieved great success in the fields of hydraulics, foundry and metallurgy and have earned a reputation. In order to better serve the protection of drinking water resources in China, Jinhui Casting Co., Ltd. currently covers 30 kinds of spheroidal graphite iron pipes and fittings of DN80-DN2600 in China. The products strictly implement the internal standards of Jinhui Casting Pipe and comply with ISO2531. , EN545 and GB13295 standards.

Although the properties of ductile iron and steel are very different, the quenching of the two is basically the same. The only difference is that the parameters of quenching of ductile iron have little to do with their own cost, including heating temperature, holding time, The cooling rate and so on, and the key depends on the matrix structure of the workpiece. Let's take a look at the temperature setting in the quenching section: When quenching ductile iron, it is concerned with its heating problem because it has a direct effect on hardness. In order to achieve the hardness of the workpiece, its quenching temperature is generally 800-900 ° C, which will have a negative impact if it is too low or too high.

The advantage of ductile iron pipe is that it is a material between rigidity and elasticity, which is the advantage to ensure the safe transfer of industrial water. Industrial water pipelines must take into account the external loads caused by soil backfilling and transportation. Therefore, it is particularly important to select pipes with excellent mechanical properties to avoid the impact of production leakage and water stop events. The high-performance Jinhui ductile iron pipe allows the conditions for burying and backfilling to meet minimum requirements and does not require welding operations, thus achieving safety and investment savings.

What is spheroidal graphite cast iron? Ductile iron is a kind of cast iron. Because the spheroidized spheroids precipitated in the metallographic structure are spheroidized into casting after the casting, the graphite is spherical and the mechanical strength is higher than that of gray cast iron. HT150, HT200, HT250, HT300, HT350, H, T are the initials of gray and iron, respectively, and the number indicates the lower limit of tensile strength in MP.) It is greatly improved, so it is called spheroidal cast iron composite manhole cover with high strength and low price. Beautiful appearance. Can be freely colored, installed, maintained...

Zhaoqing Wholesale DN1400 Ductile Iron Pipe Price The centrifugal spheroidal cast pipe is a cast iron pipe made by spheroidizing molten iron through a centrifugal casting process. The miracle of the spheroidization process occurs as follows: the molten iron is added with magnesium or a rare earth magnesium spheroidizing agent before casting, and then the flake graphite becomes spheroidal graphite. The problem with flake graphite is that it causes a "split" effect on the iron matrix. This leads to inevitable brittle cracking, while spheroidal graphite causes stress concentration due to flake graphite. Therefore, the splitting, the lightening, and the toughness of the iron matrix can be avoided. Therefore, the centrifugal ductile cast pipe has degree (three times the strength of the gray cast iron pipe), high elongation (the gray cast iron pipe elongation is zero, and the ductile iron pipe elongation is ≥10%), and corrosion resistance (30 times that of the steel pipe) ), excellent performance against earthquakes.

The ductile iron pipe adopts the "gong" brand cast iron raw material which is famous for the low content of S and P elements. It also affects the comfort and performance of the driving, and should also meet the requirements of the casting process. The product adopts the advanced and new circular production line process. The processing cost of the ductile iron is too low, it becomes weak acid, and the molecular structure of the ductile iron is excellent. The strength and impact load, some plastic cast iron manhole covers can be particularly effective in water seepage from the source, although you can take some precautions to protect employees, using a new manhole cover with ductile iron.

20181028 This week, China's carbon-reducing agent market was stable, and the low-grade recarburizer market was affected by the weak downstream trend. The price was difficult to break through, and the inventory of individual enterprises was high. The medium and high grade recarburizers were raised by the price of raw petroleum coke. Impact, corporate cost pressures increase, but limited by downstream acceptance, the price increase process is more difficult to promote, some companies raise prices, mainstream prices rose. Near the heating season, local production restrictions policies are clear, Jiangsu, Hebei, Tianjin and other places have been introduced one after another, production enterprises may be limited or not, and downstream operations have been maintained at low levels.

General calcined coal recarburizer:
This week, the mainstream price of China's general calcined recarburizer market is stable, and the market is generally trading. Downstream enterprises are affected by many factors such as environmental protection and market. The general conditions of operation are relatively stable, the demand side is relatively stable, the downstream receiving mentality is weak, the market price is stable, and there is a downward intention. Production: Ningxia area in the main producing area is currently in normal production, enterprises have more inventory, environmental inspection and acceptance work is in progress, subject to environmental protection strict inspection of the heating season, heavy pollution weather control, market start-up may be limited, stimulating prices. The production of enterprises in North China is normal, but the reaction starts low, the market is generally trading, and the enterprises have inventory.

Downstream: Domestic construction steel prices have risen slightly this week. Weekly inventory decreased significantly, and the steel billet pulled up, and the supply and demand pattern still supported the market. It is learned from the market that the market price has basically maintained an upward trend in the first three days of this week. However, as the snails fell, the trading volume began to fall, and the market mentality returned to the sidelines. "Silver 10" has been more than half. So far, the work before the heating season has not yet fully started, and the market is still based on shock operation. Considering comprehensively, it is expected that the short-term building materials market will rise slightly, within the range of 50 yuan.

Calcined coke recarburizer:
This week, the mainstream price of China's calcined coke market is stable, the price of raw materials is rising, and the production cost of enterprises is high. However, in view of the environmental impact of downstream enterprises, the low starting price, the demand for carbon-reducing agents is relatively stable, and the market is generally trading, but it is subject to cost pressure. Driven, individual companies offer up. Medium-high sulfur calcined coke: This week, the market for high-sulfur calcination coke was stable, and the market price of calcined coke in the market with a sulfur content of 1.5% was increased recently. In terms of production, this week's calcined coke enterprises started to fluctuate less, and most of them are under normal production.

Graphitized petroleum coke recarburizer:
This week, the market price of China's graphitized petroleum coke recarburizer increased. Mainly due to the rising price of raw material petroleum coke, the price is high, and the pressure on the production cost of recarburizer is increasing. Among them, the production of individual enterprises in Henan and Xinjiang was suspended due to environmental protection, and the operating rate declined. The enterprises in Jiangsu, Tianjin and Inner Mongolia started to work stably, but the heating season policy was released one after another, and the market heating season may be limited. In addition, the graphitization enterprises of anode materials in the market started to work one after another, and the output was released. Graphitization and recarburizers are highly concentrated in Inner Mongolia. Enterprises in Jiangsu Province have normal production, good shipments and smooth exports.

Forecast: The market for low-grade recarburizers is temporarily stable, and the market needs to consume inventory. Enterprises mainly rely on the implementation of fixed orders. The medium and high grade recarburizer market enterprises may start to work or will be limited. In addition, the raw material prices are high. Even if the downstream acceptance is weak, the cost pressure will push the market price to rise.

20181019 This week, the mainstream price of China's Recarburizer market is stable, the low-grade Recarburizer market is generally trading, the company's inventory is high, and the medium and high Recarburizer market is better. The heating season is just around the corner, the downstream steel mill's production restriction policy is clear, the company's operating rate is low, and the receiving sentiment is relatively dull. The Rebondurizer market price is generally stable and the possibility of deposit and loss is high. The prices of raw materials in the medium and high-grade Recarburizer market were generally raised after the holiday, and the cost pressure of production enterprises increased. However, due to the limited acceptance of the downstream market, the company's quotation has not been raised.

At present, the main materials of Recarburizer are coal and petroleum coke. The petroleum coke is divided into ordinary calcined Recarburizer and graphitized Recarburizer because of the degree of calcination. After years of tempering in the market, the petroleum coke Recarburizer has gradually replaced the market position of coal-based Recarburizer, and the shipment volume is relatively high.

Calcined Recarburizer:
This week, the mainstream price of China's general calcined Recarburizer market remained stable, and the overall market shipments were generally due to the general consumption of downstream steel mills, and the demand was relatively light. Most of the recalcinated Recarburizer manufacturers are electric calcined anthracite enterprises, self-produced screening, and the environmental protection facilities of the local enterprises in the main producing area are undergoing the inspection and acceptance of environmental protection facilities. If the enterprises fail to meet the standards or restrict production, the market starts will be limited. The production of enterprises in North China is normal, but the reaction starts low, the market is generally trading, and the enterprises have inventory.

Downstream: China's construction steel prices are trading strongly this week. Recently, in the environmentally-friendly production and the leading regions, the stock market digested and enlarged, coupled with the decrease in the shipments of the leading steel mills, the stronger willingness to price, and the support of the construction steel market continued to rise. It is understood that the Ministry of Housing and Urban-Rural Development said that all localities should take effective measures to speed up the progress of construction, increase the construction of supporting infrastructure for sheds, and the terminal demand is still acceptable. However, as the price gradually increases, the terminal transaction will gradually decrease, and the market risk preference will be lower. The high price of the willingness to accept is relatively limited, which is not conducive to the sharp rise in prices. Coupled with the recent snail and steel billet red and green intertwined, resulting in a turbulent mentality in the building materials market, traders are cautious, and the atmosphere is strong. Market outlook: It is expected that the short-term building materials market will fluctuate and strengthen, with a range of 50 yuan/ton.

Calcined Petroleum Coke recarburizer:
This week, the price of China's calcined coke Recarburizer is stable, the raw material price is high, and the production cost of the enterprise is high. However, in view of the environmental impact of the downstream enterprises, the low-level operation, the demand for Recarburizer is relatively stable, the market is generally trading, the late heating season is coming, the calcined coke Prices may fluctuate due to limited production, etc., affecting Recarburizer shipments, or will benefit other quality Recarburizer.

Medium and high sulfur calcined coke: This week, the medium and high sulfur calcined coke market was generally trading, the shipment was stable, the market was slightly weak, and the price of the coke was not adjusted. In terms of production, the production load of Zhaoxing carbon is increasing, and individual enterprises in Shandong Guangrao are not expected to reduce production. It is understood that the impact of this winter's limited production policy on calcined coke enterprises will be less than expected. A new carbon-fired enterprise in Shandong is expected to ignite four new calciners at the end of this month, and the monthly output is expected to increase by about 20,000 tons. There is no inventory backlog, and there is no pressure on the trading market of calcined coke. However, at the same time, after the production load of the enterprise is increased, coupled with the recent poor performance of the aluminum market, the price of domestic medium and high sulfur calcined coke at the end of the month is still at a downward risk, and the estimated range is about 50 yuan/ton. .

Graphitized petroleum coke Recarburizer:
This week, the price of China's graphitized petroleum coke Recarburizer is stable. The price of raw material petroleum coke is stable and the price is high. The pressure on the production cost of Recarburizer is increasing. 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. Enterprises in Jiangsu Province have normal production, good shipments and smooth exports.

Late prediction: The general market for recarburization of Recarburizer is currently trading, and the stock of enterprises is higher, but the price of raw materials for electric calcination may be lower due to limited production, which stimulates the price of Recarburizer; the price of calcined coke and graphitized Recarburizer is driven by cost. The pressure is increasing, and the price push is stronger.
