Alumina bubble brick is a high-quality thermal insulation material, which can be used as a kiln lining as an insulation layer, which can reduce the weight of the furnace body and optimize the kiln structure. The refractoriness of alumina bubble brick can reach more than 1750 degrees, and the thermal stability is good.

Benefits of using alumina bubble brick

From the perspective of cost, the price of heavy bricks and hollow ball bricks is similar, and the price of alumina hollow ball bricks for particular areas may be slightly higher than that of heavy bricks. Still, in terms of weight, the use of hollow ball bricks can reduce the cost per cubic meter. 1-2 tons. Moreover, there is no need to make an insulation layer, which reduces the amount used and saves fuel. Not only is the use effect good but the cost is also reduced.

Application of alumina bubble brick

Alumina bubble brick is a commonly used thermal insulation material in the kiln, which plays a vital role in kiln construction and production. The volume density of alumina bubble brick is small, which can reduce the weight of the furnace body well, and has a good Insulation effect, which can save energy and raw material costs.
