Excellent strength of pressure bending, abrasion proof
Excellent performance of high-temperature firing, high rates of associative property, anti-erosion ability
Excellent thermal shock resistance and spalling resistance
Excellent ability of high refractoriness, anti-erosion of alkaline residue;
High temperature load of refractoriness under load. High mechanical strength
High temperature resistance excellent corrosion resistance
Resistance to spalling

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 mainly applied to the regenerators of glass kilns and other high temperature glass furnaces.
