摘要
大型铝铸件，采用湿砂型低压铸造工艺，投资少、速度快、金属利用率高、铸件质量良好，取得了较好的经济效益．经过反复实践，确定了合理的工艺参数。
The heavy aluminum casting produced by green sand mold low_pressure casting process have many advantages,such as low investment,rapid production speed,high utility ratio of metal and good casting quality Better economic profit has been obtained in our factory The Castings can meet the technoloy standard
