The common types of carburizers in China include Graphitization Carburizing
Agent, Calcined Petroleum Coke and Calcined Anthracite Coal,
The raw materials of domestic carburizing agent are heavy oil residue in the
process of petroleum refining for coking, namely petroleum coke and asphalt
coke. Raw petroleum coke is calcined into calcined petroleum coke. Graphite
carburizing agent is obtained by graphitization of raw petroleum coke.
Graphitization can reduce the content of impurities, increase the carbon content
and reduce the sulfur content.
Carburizing agent is widely used in steel-making, casting, smelting and other
industries. The use of carburizing agent in casting can greatly increase the
amount of scrap steel, reduce the amount of iron or no pig iron. The carburizing
agent can improve the distribution of graphite, promote the graphitization of
cast iron, increase the graphite crystal nucleus and fine graphite ball of
molten iron, so as to make it more evenly distributed in the matrix and improve
the quality of products。
Calcined petroleum coke is mainly used in aluminum industry. In the process of
steel-making, Calcined Anthracite Coal can be added as carburizing agent.
Carbon Additive/Carbon Raiser is also called "Calcined Anthracite Coal",or "Gas
Calcined Anthracite Coal".
The main raw material is unique high quality anthracite, with characteristic of
low ash and low sulfur. Carbon additive has two main uses, namely as the fuel
and additive. When being used as the carbon additive of steel-smelting, and
casting, the fixed carbon may achieve above 95%.
Best quality Anthracite as raw materials through high temperature calcined at
over 2000 by the DC electric calciner with results in eliminating the moisture
and volatile matter from Anthracite efficiently, improving the density and the
electric conductivity and strengthening the mechanical strength and
anti-oxidation, It has good characteristics with low ash, low resistivity, low
carbon and high density. It is the best material for high quality carbon
products, it is used as carbon additive in steel industry or fuel.

How to use:
1)The use of more than 5 tons of electric furnace, a single stable raw material,
we recommend the method of decentralized addition. According to the requirement
of carbon content,the carbon additive and the metal charge are added into the
middle and lower part of the electric furnace together with each batch. Carbon
Additive in the melting do not slag, or easy to wrap in waste slag, affect
carbon aborption.
2).Using about 3 tons medium frequency induction furnace, the raw material is
single and stable, we recommend the method of centralized adding. When a small
amount of molten iron is meted or left in the furnace, the carbon additive
should be added to the surface of the molten iron once, and the metal chare
should be added immediately, and the carbon additive should be pressed into the
molten iron to make the carburizing agent in full contact with the molten iron.
3).using small or medium frequency electric furnace raw material cilo has iron
and other high carbon material we recommend carbon additive ine adustment. After
Molten steel molten Iron.the carbon content can be adusted and added to the
surface of the steel molten iron.The product can be dissolved and absorbed by
Eddy current or manual stirring of the steel molten iron during melting in an
electric furnace.
