Products Description
Recarburizer, also known as carbon raiser, is an essential additive used to increase the carbon content in molten metal. It is widely applied in the iron and steel industry to adjust carbon levels during smelting and casting processes. Our recarburizers are made from high-quality raw materials such as calcined petroleum coke, graphite, and anthracite, ensuring low sulfur content and excellent absorption rates.
