used in steelmaking or casting, the fixed carbon of carbon raiser When being used in steelmaking or casting,carbon additive is a material added to molten metal to increase its carbon content.  It has been widely used in various industries such as metallurgy, chemical, and power. are many kinds of raw materials and production processes for carbon raisers,  coke based carbon, graphite based carbon, with many subcategories under each category. High quality carbon raisers generally refer to graphitized carbon additives. As the carbon atoms are arranged in a graphite-like microstructure under high temperature conditions, so it is called as graphitization. Graphitization can reduce the content of impurities in the carbon additive, increase the carbon content, and lower the sulfur content. When being used in casting, carbon raisers can significantly increase the amount of scrap steel used, reduce the amount of pig iron used, or eliminate the need for pig iron.It has been widely used in various industries such as metallurgy, chemical, and power.
