Recarburizer

In order to make up for the carbon content in the iron and steel smelting process due to factors such as smelting time, holding time, and long overheating time, the carbon-containing substances added are called carbon raiser.

There are many types of carbon raiser, which can be generally divided into metallurgical coke carbon raiser, calcined coal carbon raiser, petroleum coke carbon raiser, graphitizing carbon raiser, natural graphite carbon raiser, and composite carbon raiser. Graphitization can reduce the content of impurities in the carbon raiser, increase the carbon content of the carbon raiser, and reduce the sulfur content. When casting, it can greatly increase the amount of scrap steel, reduce the amount of pig iron and even no pig iron. Therefore, graphitized carbon raiser is the high-quality carbon raiser.
