Al-Mg spinel has good corrosion resistance, strong corrosion and peeling ability, good slag resistance, abrasion resistance, thermal shock stability, high temperature resistance and other performance characteristics.
The bauxite-based sintered magnesia-aluminum spinel uses high-quality bauxite with an Al2O3 content of more than 76% and high-quality light-burned magnesium powder with a MgO content of more than 95%. It is sintered at the above high temperature, with high volume density, high mineral phase content, well-developed grains, uniform structure and stable quality. Magnesium-aluminum spinel has good corrosion resistance, strong corrosion and peeling ability, good slag resistance, abrasion resistance, thermal shock stability, high temperature resistance and other performance characteristics. It is an ideal raw material for the production of refractory products such as magnesia-alumina spinel bricks, ladle lining bricks, and ladle castables for high-temperature zones of cement rotary kilns. Magnesium aluminum spinel is widely used in refractory materials, iron and steel smelting, cement rotary kiln and glass industrial kiln.
It has good anti-erosion ability, anti-abrasion ability, and good thermal shock stability. Its main application: firstly, to replace magnesia-chrome sand to make magnesia-aluminum spinel bricks for cement rotary kiln, which not only avoids chromium pollution, but also has good spalling resistance; secondly, it is used to make ladle castables, which greatly improves Corrosion resistance of steel lining. It is widely used in refractory materials for steelmaking. The preparation of high-quality pre-synthesized spinel provides new raw materials for the production of amorphous and shaped high-purity refractory materials.
