Rebonded Magnesite-Chrome Brick for Electric Arc

Rebonded Magnesite-Chrome Brick for Electric Arc

The products are fused magnesia as main raw material, after a reasonable size distribution, high pressure forming, high-temperature sintering. The product has strong resistance to slag corrosion ability and high temperature dimensional stability. Mainly used in glass furnace regenerator, the upper part.

It is a kind of alkaline refractory product with perriclase as main phase magnesia alumina spinel clinker as basic material .The product has such characteristics as good temperature vibration, good strength and volume stability in high temperature.
