Sk*32/34/36/38 Brick, Standard Brick, 230*114*65 or 75mm Brick, Fire Birkc

Brief description of clay brick
1. Good acid stability
2. Good thermal performance
3. Good thermal shrinkage
4. Good resistance to abrasion and corrosion

Typical Application
Clay brick is suitable for secondary parts of coke oven, such as regenerator seal wall, small flue lining brick and regenerator checker brick lining brick, roof, door and rising pipe lining brick, etc. It is one of refractory brick used in blast furnaces, hot blast stove, heating furnace, power boiler, lime kiln, rotary kiln, ceramics.

Advantage of Clay Brick
Clay brick is refers to the Al2O3 content is 30% ~ 40% aluminum silicate. Clay brick is made of soft clay and 50% and 50% of hard clay grog, ingredients required by certain granularity, after forming, drying, burning under the high temperature of 1300 ~ 1400. Clay brick belongs to the weak acid refractory products, can resist acid slag and the erosion of acid gases, the alkali resistance ability is a bit poor. Clay brick has good thermal shrinkage.
