Description

1. Magnesia alumina spinel brick Description  

Magnesia alumina spinel bricks are used to improve the thermal stability of magnesia bricks, and alumina is added to the ingredients and produced. Magnesia alumina spinel bricks are made of high-quality magnesia and industrial alumina powder with low calcium content as the main raw materials, which are formed by high-pressure molding and high-temperature firing. It is resistant to quenching and rapid heating, and has good corrosion resistance to solvents such as iron oxide and alkali slag.

2. Magnesia alumina spinel brick Feature   

(1) Good thermal stability,

(2) Its anti-stripping performance is good

(3)long lasting use

(4)It can be directly combined with magnesia chrome bricks.
