China high alumina refractory brick manufacturer factory supply 90 aluminium oxide content White Corundum Brick of Glass Furnace
Corundum brick refers to refractory products with alumina content greater than 90% and corundum as the main crystalline phase. Very high temperature compressive strength (up to 340MPa). High initial softening temperature under load (> 1700℃). Good chemical stability, strong resistance to acid or alkaline slag, metal and glass liquid. The stability of thermal shock is related to its structure.
The corrosion resistance of compact products is good, but the stability of thermal shock is poor. It is divided into sintered corundum brick and fused alumina brick. Sintered alumina and fused corundum can be used respectively as raw materials or alumina clinker with high Al2O3/SiO2 ratio and sintered alumina.
Unburned corundum bricks can also be made from phosphoric acid or other adhesives. It is mainly used in blast furnace and blast furnace hot blast furnace, steel furnace outside finishing furnace, sliding water, glass melting furnace and petrochemical industry furnace.
Corundum brick has been widely used in high temperature and high pressure, severe chemical erosion and mechanical wear of petrochemical thermal lining material, with the progress of petrochemical industry production technology, a lot of new technology and new technology is adopted in production, in order to make equipment to large load, long cycle, low energy consumption, low cost, except to modify all sorts of thermal equipment, also for a variety of thermal equipment lining materials is put forward higher requirements.
Therefore, a series of chromium corundum products with better high temperature resistance and erosion resistance were developed to meet the needs of petrochemical industry
