Product introduction
1. Product definition:
High alumina firebrick is a kind of alumina silicate refractory whose content of alumina is not less than 55%.By alumina content of bauxite or other alumina
High raw materials are formed by moulding and calcining.
2. Product features:
Thermal stability, high refractoriness in above 1790 ℃, high refractoriness under load can reach above 1480 °, good slag resistance, good thermal shock stability,
Acid and alkali resistance, high temperature creep rate low, high temperature strength characteristics, belong to the high refractory.
3. Product classification:
High-alumina bricks are generally divided into four grades according to different content of alumina
4. Product use:
The first-grade high-alumina firebrick is mainly used for electric furnace cover (top), blast furnace (body), hot air furnace partition wall, steel ladle lining and steel barrel.
The inner lining of various thermal kilns, such as iron water truck, cement kiln, glass kiln, etc.Widely used in ironmaking, steelmaking, chemical industry, cement and other industries.
