The clssification of corundum brick

According to the refractory raw materials, corundum brick can be divided into sintered, rebond sintered, fused and rebond fused corundum bricks.
The first is made from sintered corundum clinker, while the third is made from light burning corundum powder particles and fine corundum powder.
The second is fused corundum refractories, including fused cast corundum refractories. Fused cast corundum refractory or fused cast alumina refractory is made by casting molten glass into a mold and then cooling it into a solid. The refractory raw materials are always melted in an electric arc furnace.
Rebond fused corundum brick is made of fused corundum clinker and fine fused corundum powder or sintered corundum powder as the matrix. The key to its production is the processing of fused corundum materials. when fused gray or white corundum used as the main refractory raw materials, the frits should be smashed first and then seleted to remove silicon iron alloy. Silicon iron alloy may cause the burst of refractory products.
