摘　　要：针对铝合金结构大盘(以下简称"大盘")浇铸成型后出现海绵状疏松,导致抗拉强度不满足设计要求。通过分析,找出铸模和铸造工艺上存在的问题,运用纠错技术改进铸造工艺方式,严格过程质量控制,从而保证最终铝合金铸件内外部质量和强度满足图纸提出的技术要求。Large disk with aluminum alloy structure appears spongy loose after casting molding,which leads to tensile strength can’t meet the design requirements. Through analysis,the problems existing in the mould and casting process were found out,and the casting process was improved by error correction technology. The process quality is strictly controlled to ensure that the internal and external quality of aluminium alloy castings and strength meet the technical requirements of the drawings.
