Glass industry furnace use erosion-resistant Alpha Beta fused alumina brick for forehearth
Description of Fused alumina brick
Fused alumina brick is made by melting alumina in an electric arc furnace and casting them into a model of a specified specific shape, annealing and heat preservation, and then processing diamond abrasive tools to obtain the desired product.
Fused alumina brick also called fused corundum blocks mainly refer to fused a, β corundum and fused β corundum blocks. It is mainly composed of 92% to 94% AL2O3 corundum crystal phase, with a density of 2.9 to 3.05g/cm3 . The highest operating temperature is around 1700℃. Fused alumina has very good resistance to glass leakage and hardly pollutes the glass liquid. It is widely used in the working part tank wall, tank bottom, flow channel, working part forehearth tank wall, forehearth tank bottom, etc. of the glass melting furnace that are in contact with the glass liquid and are required to be free of refractory material contamination.
