Magnesia bricks are mainly used for steel-making alkaline open hearth, electric furnace bottom and wall, oxygen converter lining, non-ferrous metal smelting
Magnesia refractory brick has unmatched durability, excellent heat resistance, and superior corrosion protection. These bricks are ideal for high-temp industries such as steel, cement, glass, and non-ferrous metal production. Kerui provides reliable, high-quality bricks and complete refractory solutions to meet your needs.
Features
Superior Temperature Resistance: With a melting point exceeding 2800°C, magnesia bricks excel in applications up to 2000°C, making them ideal for furnaces, kilns, and reactors.
Alkali and Slag Resistance: Excellent resistance to basic slags and alkaline atmospheres ensures prolonged service life in steelmaking, cement rotary kilns, and non-ferrous metal processing.
Thermal Shock Stability: Optimized composition minimizes cracking under rapid temperature fluctuations, enhancing durability in cyclic heating operations.
High Load Capacity: Robust structural integrity supports heavy loads at elevated temperatures, critical for industrial furnace linings.
