Dolomite brick is a type of basic refractory material mainly produced from natural dolomite (calcium magnesium carbonate).
• High refractoriness
• Excellent resistance to alkaline slag corrosion
Dolomite bricks are widely used in steelmaking furnaces and other high-temperature industrial furnaces, particularly in environments requiring strong resistance to alkaline slag.
