Typical Application
Fire 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 Fire Brick
Fire brick is refers to the Al2O3 content is *0% ~ *0% aluminum silicate.Clay brick is made of soft clay and *0% and *0% of hard clay grog, ingredients required by certain granularity, after forming, drying, burning under the high temperature of ***0 ~ ***0 ℃.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.
