Carbon riser is a product which is treated in high temperature.
And removing ash, vm, moisture. Carboriser is with low vm, moisture and sulphur so very useful for carbon pickup due to melting process in foundries.
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.
Mainly used in steelmaking in an electric furnace, it can increase the carbon content in steelmaking and ductile iron foundries, greatly increase the amount of scrap steel, reduce the amount of pig iron or eliminate the need for pig iron. It replaces traditional recarburizers and effectively reduces steelmaking costs. It is also used in metallurgy, glass production, casting, smelting of graphite crucible, aluminum, titanium, and other industries..
