High alumina brick manufacturer

Ordinary high alumina bricks are divided into LZ-75, LZ-65, LZ-55, LZ-48 grades according to physical and chemical indicators. High alumina refractory bricks have high refractoriness, high load softening temperature, good thermal shock stability, acid resistance, Anti-alkali, anti-erosion and other characteristics.

2. Application and corresponding indicators of high alumina bricks in various industries:

1. High alumina bricks for general purpose: Generally, high alumina bricks are made of bauxite clinker, supplemented by combined clay and additives.

2. High alumina bricks for blast furnace: High alumina bricks for blast furnace use selected bauxite clinker as the main raw material, formed by high pressure molding and high temperature sintering. The main mineral composition is mullite and corundum.

3. High-alumina bricks for steel-making electric furnace roofs: High-alumina bricks for steel-making electric furnace roofs are made of specially selected special grade bauxite clinker as the main raw material, which is formed by high-pressure forming and high-temperature sintering.

4. High alumina bricks for steel drums: High alumina bricks for steel drums are made of selected Yangquan bauxite as the main raw material, formed by high-pressure forming and high-temperature sintering. The main mineral composition is corundum and mullite phases. Good high temperature mechanical properties and chemical resistance.

5. Low creep series high alumina bricks for hot blast stoves: Low creep series high alumina bricks for hot blast stoves are made of corundum mullite and selected bauxite clinker as the main raw materials, through high pressure forming and high temperature sintering.

6. Low creep andalusite bricks for hot blast stoves: Raw materials and technology: low creep andalusite bricks for hot blast stoves use selected andalusite, corundum, and mullite as the main raw materials, and are formed by high-pressure molding and high-temperature sintering.

7. Mullite bricks for blast furnace:

8. a. Mullite bricks:

Raw materials and technology: Mullite bricks for blast furnace use artificial fused or sintered mullite raw materials as the main raw materials, which are formed by high-pressure molding and high-temperature sintering. The main mineral composition is mullite.

8. Corundum mullite brick for blast furnace: composite brown corundum brick
