Producing pcessing of AZS blocks ER-1681/1691/1711
1. Sand mold making:
The sand mold is made of silica sand and water glass as a binding agent according to the shape of AZS blocks ER-1681/1691/1711.
2. Raw material processing and proportioning by computer:
Raw materials such as alumina powder, zircon sand and desiliconized zirconium and other raw materials shall be put into storage for use or sent to raw materials for pretreatment after acceptance.
3. Melting process:
Mainly in accordance with the requirements of the production plan, the matched fused zirconium corundum raw materials are added to the automatically controlled electric arc furnace and melted under the best conditions.
4. Casting process:
Pour the molten material into a specially designed product mold. T
5. Heat preservation and annealing process:
The cast bricks are slowly cooled, so that the crystals of the prepared fused zirconia corundum bricks grow and form the best structure.
6. Demoulding process:
The annealed fused cast zirconium corundum bricks are taken out of the cavity using equipment for product inspection.
7. Machining rocessing:
Check the appearance defects, carry out high-precision grinding according to the requirements of users to ensure the size and surface accuracy of the bricks.
8. Pre-assembling and packing:
After Machining processing, it is pre-assembled to ensure that the product size is packaged and shipped.
Casting method of fused cast AZS bricks
AZS blocks ER-1681/1691/1711 are made by completely melting the raw materials and casting it in a casting mold, which is cooled and solidified. The shrinkage caused by the volume shrinkage of this product during condensation is a matter of special attention when using it. The casting methods of fused zirconium corundum bricks are ordinary casting (PT), inclined casting (QX), non-shrinkage casting (WS) and quasi-shrinkless casting (ZWS).
