High alumina castable
Introduction:
The high-aluminum refractory castable is a refractory castable prepared by adding high alumina bauxite clinker as aggregate and powder, and adding a binder and dispersant. It can be used to directly cast the monolithic lining, or it can be cast into a pre-formed piece.
Advantages:
1. Good thermal shock resistance
2. Good resistance to wear and corrosion
3. High mechanical strength
Application:
Blast furnace, hot blast stove, tapping tank of electric furnace, rotary kiln, boiler in power plant
