The fused cast azs block also called zirconia corundum brick is a white solid formed by pure alumina powder and zircon sand containing 65% zirconia and about 34% silica in the electric furnace after being melted and injected into the model for cooling. Fused zirconia corundum brick is commonly known as white iron brick, also known as corundum-oblique zircon brick. The main chemical components are Al2O3 45%-50%, ZrO2 32%-44%, and SiO2 12-16%. The main mineral composition is oblique zircon (ZrO2), corundum (α-Al2O3) and glass phase. Oblique zircon crystals form the backbone of the brick, ZrO2 has a high melting point (2715°C), good chemical stability, and strong resistance to acidic and alkaline media, especially glass liquid.
Fused cast azs block advantage
Fused cast azs block advantages:
1. Raw material is corundum and baddeleyite eutecticum, high compression strength
2.Top high-temperature capablility.
3.Excellent thermal stability.
4.Low thermal conductivity
5.Powerful penetrating-proof capability.
6.Good erosion-resistance.
7.Strong resistant erosion stability to the glass liquid.
