Feature

Fused Magnesia Brick Features:

Excellent performance of basic slag resistance, high refractoriness, thermal stability, anti-erosion and anti-peeling

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.

Application:

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