Magnesia Alumina Spinel Important Insulating Castable Refractory As Steelmaking Refractory Material

Description

Magnesia alumina spinel castable used in the ladle is made of superior bauxite, high quality synthetic spinel, additive and binding agent.

Product Characteristic:

1.excellent slag corrosion resistance.

2.high temperature resistance.

3.good thermal shock resistance performance.

4.long service time, safe and stable advantages.

$Magnesia Alumina Spinel Important Insulating Castable Refractory As Steelmaking Refractory Material$

Usage:

The magnesium aluminium spinel castable is the ideal ladle lining material, which can be directly poured into lining and can be made into precast blocks.

Because the magnesia alumina spinel refractory with the characters of strong resistance to slag erosion, excellent thermal shock resistance and high temperature strength, it is more and more used as steelmaking refractory material.
