The Introduction of High Aluminum Heat Insulation Brick
Also known as high aluminium heat insulating brick. A lightweight refractory material having an alumina content of more than 48%, mainly composed of mullite and a glass phase or corundum. The bulk density is 0.4 to 1.35 g/cm3. The porosity is 66% to 73%, and the pressure resistance is 1 to 8 MPa. Better thermal shock resistance.
High alumina heat insulating brick use: high aluminum poly light brick has reached various international technical indicators of similar products, and is a must select new material in industrial furnace design. It is widely used in kiln lining (not eroded by solution) and insulation layer in metallurgy, machinery, ceramics and chemical industries. It is an ideal energy saving product. Its use temperature is below 1350 ℃.
