AZS fused casting block is also called fused casting block, which is abbreviated as AZS because it contains Al2O3－ZrO2－SiO2. The fused casting AZS block is made of pure alumina powder and zircon sand (composed of 65% zirconium oxide and 34% SiO2). The fused casting AZS 33# block has a dense microstructure, which ensures that it has strong resistance in the glass liquid, so you don't have to worry about solidification and other problems. It is widely used in the upper structure of glass melting furnace, working pool side wall, paving bricks, feeding channel, trough bottom, C-shaped bricks, hopper top, etc.
