High Wear Resistance High Alumina Brick For Lime Shaft Kiln ISO9001 Compliant
Description
The first-grade high-alumina brick (the aluminum content is not less than 75% refractory brick) is formed by pressing and calcining a high-quality raw material such as high-quality bauxite and alumina. The high-aluminum brick has a refractoriness of over 1790 °C. The load softening temperature is above 1510 °C, the thermal shock stability is good, and the slag resistance is good.

Application
High-aluminum bricks are mainly used for masonry blast furnaces, hot blast stoves, electric furnace tops, blast furnaces, reverberatory furnaces, and rotary kiln linings. In addition, high-aluminum bricks are also widely used as open-hearth regenerative lattice bricks, plugs for gating systems, and shingles.
