High Quality Carbon Raiser China for Steelmaking and Casting

In order to supplement the melting loss of carbon in steelmaking need to add carbon-containing materials, such materials are called carbon raiser in China.
According to different casting purposes, the carbon raiser in China can be divided into nodular cast iron carbon raiser,gray cast iron carbon raiser,cast steel (steelmaking) and special carbon raiser. For the nodular cast iron used, it need the high carbon and low sulfur, generally the carbon content is more than 98.5% and the content of sulfur less than 0.05%, always adopt the graphitized petrpleum coke and graphitized electrode, it is in high absorption rate; For the gray cast iron used, it will be just different in the surfur content with the nodular, it need the content of surfur less than 0.5%, always adopt the non-graphitized petroleum coke and calcined coal, the absorption rate will be 85% more or less; For the cast steel used, the steelmaking factory will generally choose the carbon raiser according to different steel, always adopt the calcined coal,graphitized ball and natural graphitize granule; As for the final cast iron for brake pad and carbon cored wire, it generally use the 0-0.5mm or 0.5-1mm petroleum coke.
The raw materials of carbon raiser from China contains much various types such as woodiness carbon,coal,coke and graphite etc, among of them the high quality type is the graphitized carbon, it can increase the carbon content and reduce the surfur content after the graphitization. As describe above will know that for different cast iron need to choose different type of carbon raiser, what is more, the particle size will also be different, the general size is 1-5mm, but for the induction furnace need the particle size from 0.2mm to 6mm, for high carbon steel reuqire low nitrogen and need the particle size from 0.5mm to 5mm.
