Description
Alumina insulation brick is usually made of high alumina bauxite clinker and a small amount of clay. After being pulverized, it is poured and formed in the form of mud by gas generation method or foam method, and fired at 1300-1500℃. Occasionally, alumina can be used instead of alumina clinker. Alumina insulation brick is light weight shaped refractory material, it is used for lining and insulation layer of kilns, and for parts without strong high temperature molten material erosion and scouring effect. It can not use as a load bearing part. When in direct contact with the flame, the surface contact temperature should not be higher than 1350℃. The higher alumina content, the better product performance.
Characters:
1.Light in weight and high in porosity
2.Good thermal shock resistance
3.Low thermal conductivity and energy saving
4.Good thermal insulation effect
