CBN abrasive grit Fused corundum brick

Fused corundum brick [fused castiong alumina bricks] fused alumina bricks are melted in electric arc furnaces in the aluminum casting to a specific model of a certain shape by the annealing, and then processed by diamond abrasive to give the desired products. The crystalline form of aluminum products CBN abrasive grit‍ according to which the number of how many different and is divided into three kinds, the first one is mainly α-Al2O3 crystal phase, called α corundum brick; second is α-Al2O3 and β-Al2O3 crystalline phase mainly basic content is 1:1, α-phase content is slightly higher, called α, β corundum brick; third crystalline phase to β-Al2O3-based, called β corundum bricks. 

The product α-Al2O3 crystal phase and the β-Al2O3 based, the content of about 50%, the product crystallized dense below 1350 degrees, the corrosion resistance of the glass is excellent fused zirconia mullite‍ in after it is widely used in glass tank furnace, and the work site, the site is usually chute, lip brick, tile and other gates. Internationally fused alumina brick with Japan's Toshiba to do the most good
