Description
Fused magnesia brick use fused magnesia as main raw material, through a reasonable size distribution, high pressure forming, high-temperature sintering to make finished products. The product has strong resistance to slag corrosion ability and high temperature dimensional stability.
Application:
it is mainly applied to the regenerators of glass kilns and other high temperature glass furnaces.
Physical and chemical index:
Fused Magnesia Brick
