Fused Cast AZS Blocks S3 S4 S5 for Glass Making High Refractoriness and Al2O3 Content

China high quality refractory brick manufacturer fused cast azs blocks S3 S4 S5 for glass making industries

Henan Hongtai Kiln refractory Co., Ltd. is the main fused cast azs blocks manufacturer for glass making industry in China.

Fused cast azs blocks 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 cast azs 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 blocks are also called fused cast zirconia corundum brick, the English abbreviation is AZS, which is arranged according to the three chemical components of the Al2O3-ZrO2-SiO2 ternary system phase diagram, according to the order of their content, Al2O3 is A, ZrO2 is Z, SiO2 is taken as S. National standards use this abbreviation. For example, S3 No. 33 fused cast zirconia corundum brick is abbreviated as AZS—33#, S4 No. 36 fused cast zirconia corundum brick is abbreviated as AZS—36#, S5 No. 41 fused cast zirconia corundum brick is abbreviated as AZS— 41#.

Fused cast AZS blocks technical data:

Advantage of fused cast AZS blocks:

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.

Fused cast AZS blocks production:

Fused cast azs bricks for glass melting furnace are made of the zirconite and industry alumina as the mainly mixed raw material, melting in the electric furnace,casting, annealing, machining, then finished.

The manufacturing process of fused cast azs bricks is to mix selected zircon sand and industrial alumina powder at a ratio of 1:1, plus a small amount of NaZO (added in the form of sodium carbonate), B2O (added in the form of boric acid or borax) flux, Mix evenly, melt at 1900~2000℃, and then cast into shape, to produce fused cast bricks containing 33% ZrO2. On this basis, using partially desiliconized zircon sand as raw material, fused cast azs bricks containing 36% to 41% ZrO2 can be produced.

Fused cast AZS blocks usage:

Henan Hongtai high quality fused cast azs blocks are applied for the top and bottom structure of melting chamber of the glass.Such as melting tank, the tank wall brick, the paving brick,the forehearths and so on.The high corrosion part shall be AZS 41#, such as the feeding part, the throat,the bubble brick, the furnace weir, the burner block, the tongue brick and the discharging part and so on.

AZS-33

AZS-33 blocks are excellent in preventing the pollution of glass liquids. The possibility of causing glass stones, bubbles and basic glass phase precipitation is quite slim. Fused cast azs blocks 33 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 blocks are the standard Fused Cast AZS 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. Fused cast azs blcoks 36 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 blocks 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. Fused cast azs blocks 41 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.
