Description For Ladle Castable

Ladle castable is a kind of refractory materials used for steel ladle, which is made by adding certain amount of binding agent. Ladle castable mainly adopts high alumina and silica refractory materials. Refractory ladle castables can service a long life with safety and stability, which is a relatively ideal refractory material for steel ladle application. Lable castables have good fluidity and heat insulation property, which can service under the high temperature environment with high strength. Through appropriate solidification time, ladle castables can be constructed easily, fast and conveniently for saving time. Ladle castable is suitable for high temperature position of industry kiln and permanent lining of steel ladle, and also can be used for other non-ferrous metal metallurgy.

Properties of Ladle Castable

  • High melting point
  • Low thermal stress
  • Good stability
  • Great slag-corrosion resistance
  • High thermal stability
  • Strong resistance to basic slag erosion
  • Great resistance to all kinds of melt erosion

Application of Ladle Castable

Steel Ladle is used for steel plant, foundry work in open-hearth furnace, electric furnace and converter for receiving molten steel to pouring, and also used for glass kiln, steel furnaces, ceramic tunnel kiln, cement rotary kiln, and iron making furnaces.

Use ladle castable that is not only lower the manufacturing cost but also cam lower workers’ labor intensity, which is mainly performed on using agitator to conduct ladle castables during the construction process and completely takes advantage of mechanical equipment to raise labour productivity. But use magnesia carbon brick that will completely rely on workers’ building by handwork, which is not only very hard but also constructed very slow. Consider steelmaking industry in our nation, steel ladle of converter steelmaking with lower 80 tons steel ladle commonly use refractory ladle castables.
