High strength high alumina insulating fire bricks
Our high alumina poly light weight fire bricks use selected raw material of calcined bauxite, fire clay and other additive,adopt new manufacture method of burning up adding polypropylene granular and firing under 1300-1500℃ in tunnel kiln.
Characteristics of our high alumina insulation fire brick (YZHA-IFB):
1)High cold crushing strength
2)High softing temperature under load
3)Accurate dimension
4)Good thermal shock resistance
5)Low thermal conductivity
6)Stable heat capability
7)Small reheating liner change
Application of our high alumina insulation fire brick IFB(YZHA-IFB) :
Widely used in insulating layers of various thermal equipments and linings where no high temperature corrosion and scouring occurs.When direct touch flame, the highest temperature can not over 1350℃.
