1. Clay brick: A refractory material that uses clay as the main raw material, is processed into shapes, and then fired at high temperatures. Clay bricks have excellent fire resistance and thermal insulation properties and are widely used in the linings and doors of various industrial kilns.
2. High alumina brick: A refractory material that uses high alumina bauxite as the main raw material, is processed into shapes, and then fired at high temperature. High alumina bricks have high refractoriness and load softening temperature, good wear resistance and chemical stability, and are important lining materials for industrial kilns.
3. Silica refractory material: A refractory material that uses silica as the main raw material, is processed into shapes, and then fired at high temperatures. Siliceous refractory materials have a high load softening temperature and the ability to resist acidic slag erosion. They are often used in high-temperature equipment such as glass furnaces and cement rotary kilns.
4. Corundum refractory material: Corundum sand is used as the main raw material. A refractory material that is processed into shape and then fired at high temperature. Corundum refractory materials have high hardness and wear resistance, and can withstand strong mechanical wear and chemical corrosion. They are often used in furnace linings and furnace tubes of high-temperature industrial furnaces.
5. Mullite refractory material: A refractory material that uses mullite as the main raw material, is processed into shapes, and then fired at high temperature. Mullite refractory materials have good thermal shock resistance and high temperature creep properties, and can withstand temperature fluctuations and mechanical stress. They are often used in smelting furnaces, heating furnaces and sintering equipment in steel, non-ferrous metals, ceramics and other industries.
