The manufacturing method of zirconium aluminum composite beads mainly includes the following steps:
- Raw material preparation: Zirconium silicate, α-Al2O3, feldspar, calcined kaolin are used as the main raw materials, which complement each other in chemical and physical properties to provide the basis for the strength and wear resistance of the final product.
- Batching and mixing: According to the proportion of the formula, the raw materials are reasonably batched to ensure that all kinds of raw materials can be mixed evenly, which is the key step to ensure product quality.
- Forming: Zirconium aluminum composite phase ceramic beads are prepared by rolling into balls. This step is to physically form the raw material into a certain shape in preparation for subsequent sintering.
- Sintering: At the adjusted sintering temperature, the mixed raw materials are fully sintered, a process that enhances the toughness and wear resistance of the material. At the same time, the phenomenon of ball and powder, powder and powder adhesion into a clump is eliminated by the method of wet mixed grinding, so that the raw materials with different densities and fineness can be evenly mixed, the fineness of the powder can be appropriately improved, the temperature of sintering can be reduced, as a result, the energy consumption can be reduced.
- Quality inspection and packaging: After the completion of sintering, the quality inspection of the product is carried out to ensure that the product meets the predetermined standards and then packaged and ready to leave the factory.
