2. Magnesite is commonly used as refractory material, making magnesite bricks that are used in steel ladles and glass melting furnaces.

3. Used as casting sand material, magnesite and sand are excellent molding materials for producing cast steel, particularly manganese steel, known for their high-temperature resistance, corrosion resistance, and good chemical stability. They offer high refractoriness and resistance to metal oxidation erosion, effectively preventing chemical sanding in castings, resulting in smooth casting surfaces and clear casting profiles. Additionally, castings are less prone to defects such as main inclusion sand.

4. As the primary raw material for filling the electric furnace steel outlet and as the tamping material for the homogenizing furnace bed.
