Can recarburizers not be used in steelmaking?

In steelmaking, it is usually necessary to use recarburizers to supplement and adjust the carbon content in molten steel. Steelmaking itself has good mechanical and physical properties. Recarburizer is a ferroalloy material required for cast steel, which plays a decisive role in the internal structure of steel. Since recarburizers play such an important role in steelmaking, what happens if recarburizers are not used in steelmaking?

First, the balance of carbon elements in molten steel during steelmaking. When the molten steel is decarburized, a recarburizer is generally used to increase the carbon. If it is not added, it will definitely lead to a poor absorption rate of carbon raw materials in the molten steel, causing serious molten steel, increasing pollution from the environmental protection aspect, and reducing the quality of steel.

In steelmaking, because the molten steel is in a peroxide state, the recarburizer has a low density and cannot sink into the molten steel to react with the molten steel. The reaction surface is small, and on the upper or surface of molten steel, the phenomenon of low carbon recovery rate and reasonableness is prone to occur. The hit rate of carbon components in steelmaking is low everywhere, resulting in steel brittleness. After adding the recarburizer, the carbon deficiency problem in steelmaking can be solved, and the sulfur content in the steel can be reduced.

Through the above analysis of what happens when steelmaking does not use recarburizers, it is not difficult to find that recarburizers are ferroalloy materials for steelmaking. While adjusting the carbon content of molten steel to improve the quality of steel, it will also reduce the production of sulfur, effectively protecting our air and the health of workers. Said that the recarburizer is indeed steelmaking.
