Product Details

Wear resistant castable is a kind of super refractories which is on the basis of high level bauxite aggregate, bauxite clinker and alumina powder, pure calcium aluminate cement as binder, ultrafine powder as additive, adding the prescribed number of heat resistant stainless steel fiber. Because of its high strength and integrity, it has been widely used in electric power industry. In the fluidized bed boiler is mainly used in the separator straight segment, inlet and outlet of the separator, cone separator, etc.

Features:

  • High refractoriness, High refractoriness under load. 
  • High density, low porosity.
  • Good slag resistance and corrosion resistance.
  • High strength and wear resistance.
  • Good resistance to flake performance.
  • Good thermal shock stability.
  • Scouring resistance.
  • Good hot strength.

Application:

  • Furnaces of metallurgy industry, heat treatment furnace.
  • Furnaces of incineration of garbage, CFB boiler furnace.
  • Furnaces of chemical industry and construction industry.
