33% ZrO2 Content AZS Blocks for Glass Furnace Fused Cast Refractory 's Used Electrocast
China fused cast refractory manufacturer the second hand Electrocast used AZS blocks used for glass furnace
The main refractory material used in the glass industry is fused cast azs refractory bricks. Henan Hongtai Kiln Refractory Co., Ltd. produces a large amount of fused zirconia corundum bricks, closely controls the process of batch composition, melting, pouring, annealing and other processes to ensure the production quality of each brick.
used azs refractory bricks/ reprocessed azs refractory bricks for glass furnace 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.
Advantage of used azs refractory bricks/ reprocessed azs refractory bricks for glass furnac:
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.
