Carbon raiser means a substance containing carbon added in the smelting of steel and iron for making up the carbon content lost. In molten iron, factors such as the smelting time, holding time, and longer overheating time lead to the carbon content decreases. As a result, the carbon content will not reach the theoretical value expected for refining. That is why a carbon raiser is added, and why it is also called a carbon additive. The high-quality carbon raiser is an indispensable auxiliary additive to produce high-quality steel and iron foundries. ZHENXIN also supplies silicon nitride，ferrochrome nitride, silicon briquette, etc., ferroalloys for steelmaking and other applications.
