摘要
Abstract
Large and medium-sized semi-closed casting has the defects of sand crushing and expansion tank,it analyzed the production process and causes of defects and the corresponding improvement approaches were established.The practice shows box molding was carried out at a tilting 45° angle of the upper mouth plane of semi-closed casting,molding sand was adopted to fill the compaction;the external negative pressure tube was fabricated,the external and internal negative pressure was open at casting period to guarantee pressure balance of the external and internal chamber,the casting qualified rate was improved.关键词
