Fused Zircon Corundum Blocks For Glass Melting Furnace - China

price: contact company for price

Fused cast AZS block is also named as the fused zirconia corundum

blocks, it was made by the melting of mixtures of high purity of alumina

powder and zircon sand containing 65% of zirconia and 34% of silica in

the electric furnace. The molten mixture in the furnace would be poured

into the mould already prepared, after the cooling and demould, the

machining process will be followed. The final products is white colored

solid block.

Our products will use the industry alumina powder from local and the zircon sand from Australia as the raw materials, which will be made into the refractories containing the ZrO2 range from 33%---45%.

Our company’s innovation technique: Vacuum Casting Technology for Fused cast AZS blocks, already published

Our new production technique – the Vacuum Casting has been applied in the normal production, the relative paper: Vacuum Casting Technology for Fused Cast AZS Blocks--- an Energy—saving and Environment –friendly New Technology was published on the Germany magazine – Refractories World Forum, on the second phase in April, 2013.

Specifications were achieved by the testing to the specimens selected from the densified parts.
