摘要
详细介绍了4105Z球铁主轴承盖的铁模覆砂造型生产工艺，发现采用覆砂造型生产主轴承盖，可以明显改善原挤压造型生产时存在的皮下气孔、缩松、缩孔等铸造缺陷，大大提高工艺出品率，降低生产成本。
The permanent mold with sand lining process was used to produce bearing holder cover ductile casting. The defects, porosity, shrinkage and others, were reduced comparing to original compacting sand process.
