Detailed Product Description

High Alumina high temperature insulation Kiln Refractory Bricks Lightweight for Rotary Kiln

Application

By using the products widely in insulating layers of various thermal equipments for example blast furnace, hot blast furnace, coke oven and linings where no high temperatures melt corrosion occurs.

 

Features:

Characterized by low bulk density, maximum service temperature is 1350C., high cold crushing strength, 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, and productivity and significant economic results can be achieved.

 

 

 

Composition

This series of High Alumina Insulating Refractory Brick are made of selected high alumina bauxite, kaolin clay, and hollow microsphere. By shaping at high pressure and sintering at high temperature
