原材料

 White fused alumina / White Corundum is high grade refractory material, which made from high quality alumina powder by melting above 2000 ℃ in the electric arc furnace and cooling, classified into different grain sizes.

Processing 

描述
WFA是生产不定形和定形耐火材料的主要原料。 
Commonly used in ladle castables, iron runner materials, refractory gunning mix materials and other monolithic refractory products; 
成型耐火材料主要用于刚玉砖,刚玉莫来石,精炼钢多孔塞砖,整体喷枪,炼钢,连铸等优质原料。 
It also can be used as materials for polishing, precision casting, spraying and coating, special ceramics and high-grade refractory materials,etc.
