Description

Technical Field

[0001] The utility model relates to the technical field of preparation of zirconium corundum composite casting material, in particular to a mixing and stirring device for preparing light-weight wear-resistant zirconium corundum composite casting material. Background Art

[0002] Zirconia corundum has good resistance to melt erosion. As a high-grade abrasive, it can be used to manufacture high-performance heavy-duty grinding wheels, and has a good grinding effect on steel parts, cast iron parts, heat-resistant steel, and various alloy materials. In addition, zirconium corundum is also a high-grade refractory raw material. It is an ideal material for making high-performance sliding nozzles and immersed nozzles. It can also be used to make zirconium corundum bricks for glass melting furnaces. When processing zirconium corundum, it is necessary to mix and stir a variety of raw materials, so mixing equipment is required. The mixing equipment generally uses a single stirring paddle to rotate and stir the raw materials in the same direction. Under the action of the rotating centrifugal force, the added multiple raw materials are prone to stratification, and the raw materials are mainly stirred and mixed at the bottom, making it difficult for the raw materials on the upper part to mix with the raw materials on the bottom layer, resulting in uneven mixing of the raw materials. For this reason, we propose a mixing and stirring device for preparing lightweight and wear-resistant zirconium corundum composite castables. Utility Model Content
