carbon additive for steel making

Carbon additive, from the name will get that the function is to increase the carbon content, except the main carbon products such as calcined coal, calcined petroleum coke, graphitized petroleum coke and graphitized carbon column etc, there are several other products can be used as carbon additive for steel making, such as silicon carbide, high carbon silicon, following will introduce more details about the carbon additive.

For the high carbon silicon, the carbon content can reach 20% more or less, and the silicon content can reach 65% or 68%, so it can be used as the deoxidizer and carbon additive for the steel making; As for the silicon carbide, the SiC content will be 70%,88%,90%, can reach 97% or more, and the absorption rate of silicon can reach 90% and the absorption rate of carbon can reach 60%, so it can be used as deoxidizer and carbon additive for steel making, can also increase the carbon.

As for the high carbon carbon additive such as petroleum coke, graphite carbon etc, the carbon content can reach 95%,98.5%, for different application, such as for steel making or casting, you can choose the proper carbon additive according to the carbon content or sulfur or nitrogen content. The carbon additive for steel making have much types for choice, generally large steel mills will choose multiple carbon additive according to different steel types, the general material is calcined coal, or the graphite balls are also crushed with natural graphite. The carbon content ranges from 75 to 99%, but for the petroleum coke means high sulfur, the graphite petroleum coke means high carbon and low sulfur, also there are also much more details need to notice, such as the particle size 1-5mm or 0-0.25mm, powder, granule or column, and the packing ways small bag plus jumbo bag or more.
