Fused Cast Alumina Block

Fused Cast Alumina Block series

Fused and cast alumina products are alumina series fused and cast blocks made of high-purity alumina raw materials, which are melted in an electric arc furnace at a high temperature above 2000 ℃. Due to the use of high-purity raw materials, less impurities and almost no matrix glass phase, it has excellent low contamination performance to the molten glass.

Main Products And Applications

The crystal phase structure of the fused alumina series is composed of α- alumina and β- alumina, which has different composition ratios.The products of different varieties have different properties and can meet different operating conditions.

According to its crystal phase structure, it is divided into a- β corundum brick (RTK-M) β- corundum brick (RTK-H) and a-corundum brick (RTK-A). Further classification shall be made according to the appearance quality specification level and casting method. These classifications can meet the different application requirements of fused cast corundum series in glass furnaces and metallurgical electrolyzers.
