| 摘 要： | 由于Al-Mg合金金属型铸造易产生热裂,在生产食品机械外壳大型薄壁铸件时,多以湿砂型或半金属型-半湿砂型方式生产.针对金属型工艺生产大型薄壁铸件比较困难的问题,提出一种倾转式重力铸造工艺,结合模具设计、浇注参数的调整,实现了全金属型大型Al-Mg台金薄壁铸件的生产.实践证明,本工艺可广泛应用于薄壁铸件或易产生热裂合金铸件的生产.

| Abstract: | Large thin-walled Al-Mg alloy housing for food machinery was usually produced by green sand casting or semi-permanent mold integrating with semi-green sand mold casting because of the easy occurrence of hot crack of Al-Mg alloy in permanent mold.A tilting gravity casting was presented to eliminate the problems in permanent mold casting.Considering mould design and adjusting the pouring parameters,large thin-walled Al-Mg alloy housing was produced successfully by permanent mold gravity casting.The practical ... |
