Second hand Fused Electrocast zircon corundum used bottom plate for glass melting 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.
Second hand Fused Electrocast zircon corundum used bottom plate for glass melting 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.
used azs refractory bricks/ reprocessed azs refractory bricks for glass furnace:
AZS-33
AZS-33 bricks are excellent in preventing the pollution of glass liquids. The possibility of causing glass stones, bubbles and basic glass phase precipitation is quite slim. It can be applied to the upper structure of melting pool, the tank wall corner tiles,paving bricks and other approaches as well.
AZS-36
AZS-36 bricks are the standard Fused Cast AZS Refractory bricks brick which boasts of the quality of particularly high corrosion resistance of glass liquids and low pollution. More than that, it has a balanced performance in the above two aspects. It can be applied to the direct access of glass furnace and glass liquids, such as melting tank wall corner tiles, paving bricks and charging door.
AZS-41
AZS-41 bricks are the best oxidated zircon corundum brick which possesses the quality of highest corrosion resistance of glass liquids and excellent low pollution of glass liquids. It can be applied to the locations of glass furnace which requires particularly high corrosion endurance, such as full-fused furnace, liquid pumps, furnace ridge, bubbling brick and bricks of charging door corners.
Advantage of used azs bottom plate 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.
