Refractory Materials
FUSED SPINEL
Fused Aluminum-Magnesium Spinel is smelted by adopting high purity powdered magnesium and powdered commercial Alumina through large-scale high-temperature electric arc furnace. It is characterized by high density, good appearance and color, strong corrosion resistance, good thermal shock. It is widely used for refractory products, such as steel-making electric furnace roofs, converter and ladle, large cement rotary kiln, cement rotary kiln, and glass regenerator.
