Description
Sintered zirconium corundum bricks are made of imported high-purity raw materials, fused raw materials, ultra-fine powder and composite admixtures through high pressure forming and high temperature sintering. The glass liquid has the characteristics of strong erosiveness, high temperature resistance, good thermal shock stability, excellent high temperature creep resistance, strong corrosion resistance to slag and glass liquid, etc., and is used in glass furnace lattices, small furnaces, working pools, domes and forehearths and other parts.
Features
Compared with fused zirconium corundum bricks, the chemical composition of sintered zirconium corundum bricks is similar. But it has the advantages of no carbon, low glass phase content, uniform structure, no shrinkage cavity, good thermal shock stability and corrosion resistance.
