The production process for manufacturing Ordinary refractory materials generally includes calcination of raw materials, selection of raw materials, crushing, batching, mixing, trapping, forming, drying, firing and other processes.
Refractories are generally used in metallurgy, glass, cement, ceramics, mechanical thermal processing, petrochemical industry, power and national defense.
Common refractories commonly used include silica brick, semi silica brick, clay brick, high alumina brick, magnesia brick, etc.
Special refractories commonly used include AZS brick, corundum brick, directly bonded magnesium chromium brick, silicon carbide brick, silicon nitride bonded silicon carbide brick, nitride, silicide, sulfide, boride, carbide and other non oxide refractories; Calcium oxide, chromium oxide, alumina, magnesium oxide, beryllium oxide and other refractory materials.
The frequently used thermal insulation and refractory materials include diatomite products, asbestos products, thermal insulation board, etc.
The frequently used amorphous refractory materials include furnace mending materials, refractory ramming materials, refractory castables, refractory plastics, refractory mud, refractory gunning materials, refractory projectiles, refractory coatings, light refractory castables, gun mud, etc.
