Brief description of fire clay brick
1. High refractoriness.
2. Good spalling resistance and wear resistance.
3. Good corrosion resistance.
4. Good thermal shock resistance.
5. High mechanical strength.
6. High-temperature creep rate is low.
7. Good volume stability at high temperature.
8. Low bulk density, low thermal conductivity, good thermal insulation performance. 9. Refractory category allow direct contact of fire, suitable ofr various atmosphere *0. Good integrity with furnace lining, long service life, easy operation, could be shaped freely

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.
