Applications of refractory

1. It is used to produce cast steel slide gate, lining (wall and tube) of smelting rare metal, special alloys, ceramics, iron blast furnace, spark plug, heat resistant and oxidation resistant coating.
2. Corundum insulation materials, such as corundum lightweight bricks, corundum bubble alumina bricks and fiber products, it is widely used in furnace walls and furnace roofs of various high-temperature furnaces, which are resistant to high temperature and heat preservation.

Application of abrasives

1. Grinding metal, such as a variety of common steel, malleable iron and hard bronze, etc.
2. Grinding media, sandblasting media; surface cleaning, sandblasting, polishing, grinding, etching, wet and dry blasting, mineral skin abrasion materials.
3. Metal finishing & surface preparation, ceramics, coatings, bonded & coated abrasives.
