▶ 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.
