Aluminum Magnesium Spinel
Product Description
Fused magnesia-alumina spinel is made of high-quality industrial alumina and high-purity light-burned magnesia as the main raw materials, and is melted at a high temperature of more than 2000℃ in an electric arc furnace. It has the characteristics of high bulk density, good thermal stability, good slag resistance, good thermal shock stability, strong erosion resistance, strong corrosion resistance, and high temperature resistance. It is widely used in medium and high-grade shaped and unshaped refractory materials, steel smelting, cement rotary kilns and glass industrial kilns.
