一、概况我厂大型铸件车间原来的型砂处理非常落后。肩挑人扛,劳动强度大,粉尘密度高,生产环境恶劣。为了改变这种落后状态,72年8月决定建立型砂处理半自动化生产线,9月开始设计施工,广大职工坚持自力更生,大干苦干,自制各项设备,于73年3月胜利完工,经两个月调试,5月正式投入生产,全线建成投产仅用九个月的时间。投产以来,机械设备运转良好,配制的型砂质量、数量都满足了车间生产的要求,而且还有潜力,为今后的大型铸件半自动化生产线上马提供了有利条件。 I. Overview The original sand treatment in the large casting workshop of our factory was very backward. Shoulder picking people, labor intensity, high dust density, poor production environment. In order to change this backward state, in August, 72, it decided to establish a semi-automatic sand production processing line. In September, it began to design and construct. The employees insisted on self-reliance, worked hard, and made various equipment. It was successfully completed in March of 73. Months of debugging, officially put into production in May, the entire line completed and put into production only used nine months. Since it was put into production, the machinery and equipment have been operating well. The quality and quantity of the formulated sand have met the requirements of the workshop production, and they have the potential to provide favorable conditions for the future large-scale casting semi-automatic production line.
