Magnesia Alumina Spinel Brick
1. Good Thermal Stability;
2. Strong Resistance to Erosion;
3. Lower Thermal Conductivity;
4. Good Resistance to Peeling;
Applications
Magnesia alumina spinel bricks are mainly used as good refractory products in non-ferrous metal smelting furnaces, such as steel nickel furnaces and aluminum smelting furnace linings, electric furnace covers, steel drum linings, steel refining vacuum treatment equipment linings, high-temperature belt linings in cement calcination kilns, steel storage chambers in open hearth furnaces, and lattice bricks in glass furnace heating chambers.
