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.

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