High alumina brick

High alumina brick is a refractory material, the main component of this refractory brick is Al2O3. Mainly used for masonry blast furnace, hot stove, electric stove roof, blast furnace, reflector furnace, rotary kiln lining. In addition, high alumina bricks are also widely used as hearth regenerative lattice bricks, plugs used in casting systems, nozzle bricks and the like. 

There are many types of high alumina bricks, they serve different purposes in their respective fields.

Raw materials and technology: Generally use high-alumina brick high-quality bauxite cer, combined with clay and additives made.

Features: Products with high refractoriness, good resistance to acid and alkali erosion, high temperature strength, good thermal shock stability and so on.

Uses: Widely used in llurgy, petroleum, chemical, building materials, machinery, processing and other industries thermal equipment.

High alumina brick blast furnace Raw materials and process: The high alumina brick for blast furnace is made of high-quality bauxite cer as the main raw material. After high-pressure forming and high temperature sintering, the main mineral composition is mullite and corundum.

Features: The product has excellent high temperature mechanical properties and chemical resistance to corrosion.

Uses: used in various parts of the blast furnace lining.

High-temperature furnace with low creep high-alumina brick

Raw materials and technology: Low-creep high-alumina brick for hot-blast stove is mainly made of corundum-mullite and Yangquan high quality bauxite cer, which is made by high-pressure forming and high temperature sintering.

Features: Product load softening temperature, high temperature creep resistance, good thermal shock resistance.

Uses: medium-sized stove is the preferred material.
