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合金薄壁铸件的生产。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 production shows that the technology can be widely used to produce thin-walled parts or easily-hot crack alloy parts.
