Do You Know These Advantages of Sunrise corundum bricks?

Corundum brick refers to a refractory product having a content of alumina greater than 90% and a corundum-based crystal phase. Has a very high room temperature compressive strength (up to 340MPa), a high load softening start temperature (greater than 1700 ° C) and good chemical stability, strong for acidic or alkaline slag, metal and glass Resistance. Corundum bricks are divided into sintered corundum bricks and fused corundum bricks. Sintered alumina and fused corundum can be used as raw materials or alumina clinker with high Al2O3/SiO2 ratio and sintered alumina can be prepared by sintering method. Phosphorus or other binders can also be used to make unfired corundum bricks. Mainly used in ironmaking blast furnace and blast furnace hot blast stove, steelmaking furnace outside refining furnace, sliding water, glass melting furnace and petrochemical industrial furnace. The raw material used in corundum brick is a solid solution which is synthesized by a certain ratio of alumina and chrome oxide and melted at a high temperature. The use of special refractory production process to make refractory bricks can improve and improve the intrinsic quality of the products and improve the high temperature performance of the products.

Sunrise refractory corundum brick has been widely used as a lining material in petrochemical thermal equipment with high temperature, high pressure, chemical corrosion and mechanical wear. With the advancement of production technology in the petrochemical industry, many new technologies and new technologies have been adopted in production. In order to achieve the goals of heavy load, long cycle, low energy consumption and low cost, in addition to reforming various thermal equipment, it also puts higher requirements on the lining materials of various thermal equipment. Therefore, a series of chrome corundum products with high temperature resistance and corrosion resistance have been developed to meet the needs of the petrochemical industry.
