Description
Magnesia alumina spinel brick is a kind of alkaline refractory product with periclase as main phase and magnesia-alumina spinel clinker as basic material. The product is of good temperature vibration, good strength and volume stability in high temperature environment.
Magnesia-aluminum spinel brick is a new type of refractory material made by replacing magnesia-chrome spinel in magnesia-chrome brick with magnesia-alumina spinel. It is a series of crystals with the same structure as magnesia-alumina spinel MA. Magnesia-aluminum spinel bricks have excellent characteristics such as low porosity, high strength, good thermal shock stability, and erosion resistance. This product enables the simultaneous consumption of materials in the transition zone and the firing zone, and improves the service life of the rotary kiln lining.
Low ASR, strong alkali resistance, strong resistance to alkali salt penetration, chromium-free and low iron, can effectively solve the common chemical damage of cement kilns, ensure the efficient and safe operation of cement kilns, and achieve the purpose of saving energy, reducing consumption and saving costs.
We can provide different types of magnesia alumina spinel bricks to meet the needs of different cement kilns.
