Product Description

High Alumina castables are mixed by high quality bauxite, mullite, andalusite or Corundum as aggregate, Silica Powder, α-alumina powder as micro powder, refractory cement as binder, also some additive to make better performance. Formulas are changed according to different applications.
Comparing to conventional dense castables, high alumina castables can be used in the area that have more higher temperature and also have higher cold crushing strength.


Applications

Steel Industrial (Ladle, Tundish, Induction Furnace,etc)
Incinerators
Aluminium
Cement Industrial

Features
Excellent abrasion resistance
Excellent high-temperature resistance
