Detailed Product Description
High Alumina Refractory Insulating Brick
Composition
This series of High Alumina Insulating Refractory Brick are made of selected high alumina bauxite, kaolin caly, hollow microsphere as the mian material.By shaping at high pressure and sintering at high temperature
Application
By using the products widely in insulating layers of various thermal equimentsfor example bast furnace,hot blast furnace,coke oven and linings where no high temperatures meltcorrosion
occurs.
Features:
Characterized by low bulk density,maximum service temperature is 1350C., high cold crushing strengh,size precision and hold the most stable and lowest thermal conductivity of all insulating refractory bricks at present.
The total weight of the furnace body and walls thickness can be reduced effectively,thermal efficiency and working condition can be improved,energy consumption can be lowered,produtivity and significant economic results can be achieved.
