| titleOfInvention | Manufacturing method of composite ceramic closed impeller containing metal framework |
| abstract | The invention discloses a method for manufacturing a composite ceramic closed impeller containing a metal framework in the field of application of wear-resistant protective coatings of impellers, which comprises the following operation steps: (1) preparing an impeller framework; (2) preparing an outer diameter mold and a foaming core mold; (3) assembling the impeller mold; (4) connecting injection equipment; (5) preparing a casting material; (6) vacuumizing the casting material; (7) injecting materials; (8) injecting and curing; (9) disassembling the mould; (10) and (5) detail grinding operation. The vacuumizing step in the production process is carried out in the process of mixing the casting materials, and the entrained bubbles in the casting materials are removed before the materials are poured. And two-stage process of heating and curing after material injection is finished is adopted, so that the operation difficulty in the material injection process is reduced, the waste cleaning work of the material is convenient, the reasonable arrangement of the staff shifts in the production section is facilitated, and the comprehensive advantages of simple design, stability, reliability, excellent quality and cost economy are achieved. |
