Calcined/ Burnt Dolomite For Steel Making

Calcined dolomite is obtained by the calcination of dolomite, with a high content in calcium and magnesium carbonate CaMg(CO3)2. Calcined dolomite is a material that is widely used in the steel industry due to its ability to withstand high temperatures and neutralize acidic impurities.

Refractory Lining

The refractory lining of steel furnaces is a critical component in the production of steel. It is responsible for lining the interior of the furnace, protecting it from the extreme temperatures required to melt and refine steel. Calcined dolomite is an ideal material for this application due to its high melting point and resistance to thermal shock. It is commonly used to line the walls and floors of steel furnaces, ensuring a safe and efficient process.


Sulfur is a common impurity found in many raw materials used in the steelmaking process. It can cause defects in the final product, reducing its quality and value. Calcined dolomite is a natural desulfurizing agent that can be added to the steelmaking process to neutralize sulfuric impurities. It reacts with the sulfur, forming calcium sulfide, which can be easily removed from the steel.

Slag Formation

Slag is a byproduct of the steelmaking process that is formed when impurities in the raw materials combine with fluxes and other additives. Calcined dolomite is often used as a fluxing agent due to its ability to react with acidic impurities, forming a basic slag that can be easily removed from the steel. This helps to improve the efficiency of the steelmaking process and ensure a high-quality final product.

Calcined dolomite is a versatile material that is widely used in the steel industry due to its ability to withstand high temperatures and neutralize acidic impurities. Its applications include refractory lining, desulfurization, and slag formation. As the demand for high-quality steel continues to grow, the use of calcined dolomite is likely to increase, making it an essential component of the steelmaking process.
