Synthetic spinel adopts two production processes: sintering method and electrofusion method. The raw materials are mainly magnesite and industrial aluminum oxide powder or bauxite. The indicators of magnesium oxide and alumina are different, which are divided into magnesium rich spinel and aluminum rich spinel, and are used in different fields. The characteristics of synthetic spinel materials: because the raw materials of spinel contain industrial aluminum oxide powder or bauxite, therefore, The characteristics of spinel stone must be above aluminum oxide powder and bauxite. Spinel stone has good corrosion resistance, corrosion resistance, peeling resistance, slag resistance, strong wear resistance, good thermal stability and high temperature resistance
Application: sintered spinel stone is commonly used in cement rotary kiln, ladle castable and refractory for steelmaking. Fused spinel is an ideal material for manufacturing sliding plate, nozzle brick and open hearth brick. It is the basic raw material for large-scale cement kiln filter belt, high-grade castable and high-grade kiln furniture
