Magnesia-Alumina-Spinel bricks were considered as state of the art for chrome-free kiln linings in the cement industry.

Available standard MA-spinel bricks differ mainly in the type of magnesia and in the amount and type of their alumina carrier (sintered and fused MA-spinel, calc. alumina, white fused alumina, etc.

In the past, Magnesia-Alumina-Spinel bricks were considered as state of the art for chrome-free kiln linings in the cement industry. 

We developed alumina - magnesia spinel car-bon bricks.This product possesses such anvantages as high load softening point ,low porosity,slag-resis-tance and erosion-resistance,When used in the working linings of lable,its effect is evidently raised ,so it is very popular Inmetallurgicol enterprises
