Product Description

Product Description

Magnesia Refractory Brick is a basic refractory material manufactured from high-purity magnesite, designed for high-temperature industrial furnace linings operating under severe thermal and chemical conditions.

With excellent resistance to alkaline slag, high refractoriness, and strong mechanical strength, magnesia bricks are widely used in steelmaking furnaces, cement kilns, lime kilns, and metallurgical furnaces, especially in high-temperature working zones.

Different MgO grades (95% / 97% / 98%) are available to meet various furnace operating requirements.
