消失模铸造生产线中磁选机的改造

Transformation of magnetic separator in lost foam casting production line

消失模铸造是一种近无余量、精确成型的绿色铸造工艺,磁选机是消失模铸造中砂处理生产线实现铸件落砂、杂质筛分、铁豆磁选输送和旧砂输送与冷却自动进行,旧砂回收和再利用的关键设备,与生产成本关系密切,且随着国家铸造行业的发展和智能化制造的推广及自动化生产技术水平的不断提高,其作用将越来越大。本文通过对磁选机结构、性能的改造,大幅降低了设备故障,保证了高效的旧砂回收和再利用,降低了生产成本,提高了企业竞争力。

Lost foam casting is a green casting process with nearly no allowance and precise molding.Magnetic separator is a sand treatment production line in lost foam casting to realize automatically casting falling sand,impurity screening,iron bean magnetic separation conveying and old sand conveying&cooling.The key equipment for the recovery and reuse of old sand is closely related to the production cost and its role will become larger and larger with the development of the national foundry industry,the promotion of intelligent manufacturing and the continuous improvement of the level of automatic production technology.Through the transformation of the structure and performance of the magnetic separator in the text,the equipment failure and the production cost have been greatly reduced,while the efficient recovery and reuse of used sand has been ensured and the enterprise competitiveness has been improved.
