Corundum brick is a refractory product with alumina content over 90% and corundum as the main crystal phase. Corundum bricks advantages outstanding, strong chemical stability and strong resistance to acid or alkaline slag, metal and liquid glass, both have strong capacity for resistance.
The corundum brick is divided into sintered corundum brick and fused corundum brick. Sintered alumina and fused corundum can be used as raw materials respectively, or bauxite clinker of Al2O3/SiO2 can be combined with sintered alumina to be made by sintering method. Also can use phosphoric acid or other binder to make unburned corundum brick. This series of refractory bricks is mainly used in ironmaking blast furnace and blast furnace hot blast furnace, outside steel smelting furnace, sliding water heater, glass melting furnace and petrochemical industry furnace etc.
Corundum bricks advantages remarkable，and has been widely used as lining material in petrochemical thermal equipment with high temperature, high pressure, chemical erosion and severe mechanical wear. With the progress of production technology in petrochemical industry, many new processes and technologies have been adopted in production to achieve the purpose of large load, long cycle, low energy consumption and low cost. In addition to the transformation of various thermal equipment, the lining material of various thermal equipment also put forward higher requirements.
Corundum bricks advantages：
1. Excellent fire resistance and high wear resistance;
2. High strength and good chemical stability;
3. Good thermal shock stability and corrosion resistance;
4. Widely used in petrochemical, metallurgy, coal gasifier, residue gasifier, pulp waste gasifier, carbon black reaction furnace and other industrial furnace lining.
