Abstract: carbon additive, as its name implies, is used to increase the carbon content of iron melting or steelmaking. If it is formed by graphite powder, which can greatly increase the amount of scrap steel, reduce pig iron or do not use pig iron. Carbon additive can reduce casting cost to a certain extent.

The classification of carbon additive for casting can be divided into several different categories according to different classification criteria and standards.

1. According to casting purpose, it is divided into: nodular iron carbon additive, gray iron carbon additive, cast steel carbon additive, special carbon additive:

1.1 ball iron carburizing agent generally uses graphitized high carbon and low sulfur products, the basic requirements are: C>98.5, S<0.05; its main material is graphite fossil oil coke, graphite electrode and so on. It also has the highest absorption rate and fastest absorption time in carburizing agents.

1.2 the main technical index of gray iron carburizing agent and nodular iron carburizing agent is the control of sulfur. The general requirement is S<0.5, and C content can be selected according to the cost control requirements 98.5 95 93 90. The absorption rate of this kind of carburizing agent is about 85%. Its main material is non graphite fossil oil coke, calcined coal and so on.

1.3 cast steel type of carburizing agent is more complex. In general, large steel mills choose a variety of carburizing agents according to different kinds of steel, but the general material is calcined coal, or Shi Moqiu, and it is also useful for natural graphite. The content varies from 75-99.

1.4 special carburizing agents are mainly used for brake block manufacturing, core wire manufacturing, and 0-0.5 or 0.5-1MM granularity.

Calcined petroleum coke is a high purity carbon material produced by heating green petroleum coke to drive off moisture, volatile matter, and impurities and to increase its electrical conductivity, which is used to improve the carbon content in steel-making and ductile iron foundry. It is widely used to produce graphite electrode, graphite blocks, brakes pads and other carbon products. it can also be used as carbon additive in some steel and aluminum plants, another, it is used in refractory, insulation, filler,etc. We can supply different grades of Graphited Calcined Petroleum coke.

Foshan Yoshida Casting Material Co., Ltd. is a carbon material comprehensive industrial company integrating R & D, production and sales, and the main products are calcined petroleum coke, graphited calcined petroleum coke and other carbon additive products.

Afterwards, through crushing, screening and classification, we supply our users with the different particle size as the customers' request like 0-1mm, 1-3mm, 1-5mm, 8-30mm and more, alos the specifications.

Thank you for your patient reading! We welcome your inquiry.

In order to serve you best and save your time, sending specifications technical data of the goods you are looking for is warmly welcomed. ( fixed carbon, sulphur, ash, etc)
