Refractory castables for iron ladle
规格：25kg/袋
At present, the materials used in domestic refractory masonry of iron ladle are clay bricks, three-level high alum bricks, aluminum-silicon carbide refractory casting material, corundum silicon carbide refractory casting material. The casting material used by Japanese B company for 300t iron water ladle is muscovite-corundum-silicon carbide, and the service life of iron water ladle more than 600 times; the casting material used by Japanese Dagong refractory for 200t iron water ladle is aluminum carbon and the service life of iron water ladle is 600-700 times. The casting material used by Japanese Kawasaki refractory for 50t iron water ladle is high alumina-silicon carbide, and the service life of iron water ladle is more than 600.
The refractory casting material of iron ladle is made of aluminum-silicon carbide, which is made of raw materials such as alumina fused alumina and silicon carbide; high-performance refractory casting material of iron ladle is made of corundum, silicon carbide and anti-osion agent as the main raw materials. This product has the advantages of good anti-falling, corrosion resistance, and iron slag scouring resistance.
product is widely used in: iron water ladle, solution transfer ladle, silicomanganese iron alloy furnace transfer ladle, chute and other high- industrial furnaces in the foundry and ironmaking industry.
