Light Weight High Alumina Insulation Refractory Brick
The Description:
It is usually made of high bauxite clinker with a small amount of clay, which is poured and formed in the form of mud by gas generation or foam method after grinding, and is fired at 1300 ~ 1500ºC. Sometimes industrial alumina can be used to replace part of the alumina clinker. It is used for lining and insulating layer of masonry kiln, as well as parts without erosion and scouring of strong high-temperature molten material. When directly in contact with the flame, the surface contact temperature shall not be higher than 1350ºC.

Product feature:
Light Weight High Alumina Insulation Refractory Brick is made by foam quick-setting technique,which is characterized by small bulk density,high CCS,hrul,small dimension tolerance and good thermal shock resistance.It has the lowest and most stable thermal conductivity in all the types of insulating refractory bricks,which is widely used in insulating layers of all kinds of thermal equiment.It reduces the total weight of furnace body and thickness of furnace wall effectively,improve heat efficiency,lower energy consumption,improve work conditions,improve production efficiency and considerable economic benefit can be obtained.
