Description of Alumina Magnesia Spinel Castable
Alumina Magnesia Spinel Castable is a kind of unshaped bulk refractory material which is used to make a certain amount of binder.The steel ladle refractory castable is made of high quality bauxite, corundum and high quality magnesia as the main material, and the composite micro powder and some additives are added to make it, an amorphous refractory material.
Alumina Magnesia Spinel Castable Characteristic
1.High temperature resistance, high strength, good volume stability.
2.Good thermal insulation performance, reasonable solidification time.
3.Resistance to erosion, erosion resistance and thermal shock resistance.
