Product Description

Standard refractory hollow brick high alumina checker firebricks for hot blast stove

Product Description

Checker Brick is a kind of heat carrier with features of good volume stability, excellent high temperature load creep property, high density and low apparent porosity for application in hot blast stove of blast furnace and flame furnace.

Checker Bricks are mainly used in the hot blast stove. When the hot wind is lower than 900ºC, generally adopt fireclay bricks. When the wind temperature is higher than 900ºC, adopt high alumina refractory bricks, mullite brick, sillimanite brick and silica refractory bricks and etc.

Features of Checker Brick

1.Good volume stability
2.Good high-temperature loading creep property
3.High bulk density
4.Low apparent porosity

Application of Checker Brick

Regenerative chamber in the hot blast stove
Blast furnace flame furnace
