36×117型磁选机轴承端盘在生产中主要用来密封。原来的铸件生产采用砂型造型工艺,但工艺上的缺陷导致产品的合格率低,密度差,且存在气孔质量缺陷。经过技术攻关,变原来的砂型造型为砂型、金属型混合造型。造型工艺改进后,产品合格率大幅度提升,气孔质量缺陷得以改善,确保了产品的工期及后续加工。
36 × 117 type magnetic separator bearing end plate in the production of mainly used to seal. The original casting production using sand molding process, but the process of defects lead to low pass rate, poor density, and the existence of stomatal defects. After technical research, change the original sand shape for the sand, metal hybrid shape. Improved molding process, a substantial increase in product yield, porosity defects can be improved to ensure that the product duration and follow-up processing.
