The refractory brick used for kiln car is clay brick and high aluminum brick. The clay brick has high cost performance, and can play its high temperature resistance and thermal shock performance in the pre-heat zone and cooling zone. The high aluminum brick can play the performance of high temperature resistance, corrosion resistance and high temperature volume stability in the firing zone.
Refractory brick for tunnel kiln car needs to be embedded inside the kiln car. When designing the shape of refractory brick, the masonry construction of refractory brick should be taken into account, and the practicability and service life of refractory brick for kiln car should be guaranteed.

3, wear resistance: due to the high hardness and density of refractory brick, its surface is not easy to wear, so it can maintain the surface finish and mechanical strength at high temperature for a long time.
4, good thermal insulation performance: the composition of firebrick often contains some thermal insulation materials, such as expanded perlite, expanded vermiculite, etc., these materials can improve the thermal insulation performance of firebrick, so that it has excellent thermal insulation performance in high temperature environment.
5, good chemical stability: the material composition of firebrick does not contain active metals and oxides, is not easy to be absorbed or dissolved, has good chemical stability, can maintain stable performance in a variety of harsh chemical environments.
Our total annual production capacity is about 100,000 tons of dense-shaped refractory product, and 100,000 tons of monolithic refractory product.
We have three tunnel kilns for silicon-aluminum dense bricks and one new plant for the monolithic refractory.
We're sure our custom-made products and professional services will bring you a stable quality supply and more profit.
