在大跃进形势的推动下,新建或改建的机械化铸工车间不断的创造新的高产记录,正因为这样,造型机的数量及生产率往往到受铸工输送器运送能力的限制,有的工厂把制好的砂型堆积在造型机旁边,阻塞了通道,更重要的是生产能力不能充分发挥. In the wake of the Great Leap Forward, newly built or rebuilt mechanized foundry shops continue to create new high-yield records. Because of this, the number and productivity of molding machines tend to be limited by the capacity of the castor conveyors. Some factories make good Of the sand stacked in the molding machine next to the blockage of the channel, more importantly, the production capacity can not give full play.
