Corundum brick sales refers to alumina content more than 90%, and corundum as the main crystal phase of refractory products. It has a high compressive strength at room temperature, can reach 340MPa, has a good chemical stability, acid slag or alkaline slag, metal and glass liquid have a strong resistance.
This series of refractory bricks can be divided into two types: sintered corundum brick and electrofused corundum brick. Used as sintered alumina and electrofused corundum as raw material or alumina clinker with high Al2O3/SiO2 ratio with sintered alumina, made by sintering method. Phosphate or other binder can also be used to make unburned corundum bricks. Mainly used in ironmaking blast furnace and blast furnace hot blast furnace, outside refining furnace, sliding water, glass melting furnace and petrochemical industrial furnace etc.
For now, corundum brick sales has been widely used in high temperature, high pressure and chemical erosion and mechanical wear of severe petrochemical thermal lining materials, and with the progress of petrochemical industry production technology, a lot of new technology and new technology is adopted in refractory production, in order to make equipment to large load, long cycle, low energy consumption and low cost. In addition to the transformation of various thermal equipment, we also put forward higher requirements for the lining materials of various thermal equipment. For this reason, we have also developed a series of chrome corundum products with better high temperature resistance and corrosion resistance to meet the needs of the petrochemical industry.
The raw material used in the corundum brick sales is a kind of solid solution synthesized by the melting of alumina and chromium oxide in a certain proportion. It can improve the inner quality and the high temperature performance of products by using special refractory production technology to make refractory brick. I plant professional production of all kinds of refractory products, welcome to consult and purchase.
