| 摘 要： | 在粘土砂湿型、手工造型条件下，通过厚壁大型G-AlSi10Mg铸件的工艺试验与改进，对浇注系统进行了工艺优化。实践表明，运用大孔出流底注式浇注系统、冒口与冷铁配合的工艺，可以实现厚大件的均衡凝固，消除缩孔（松）缺陷，提高工艺出品率，浇出合格铸件。

| Abstract: | Under the condition of hand-molding with green clay sand,improvements in process for large thick-walled G-AlSi10Mg alloy frame castings was conducted to optimize the gating system.The experiment indicates that using bottom gating system with large orifice discharge in conjunction with installing cold iron and riser-head can realize the proportional solidification and then avoid shrinkage porosity (hole),so that qualified frame castings is poured and the production rate is improved. |
