我厂过去几年对吊车电磁盘定量控制作了一些试验,取得了一定成绩。四年多来的事实证明,根据电动称量车上工人的指挥,吊车工人用断续控制电磁盘办法控制电磁盘放料数量,基本上能满足生产需要,起到定量加料的作用。我厂3～15吨冲天炉采用了这种定量加料方法,效果很好。工作情况如图1所示。 Over the past few years I plant on the quantitative control of the crane disk made some tests and achieved some success. The fact that more than four years have passed shows that under the command of workers on electric weighing vehicles, crane operators control the discharge quantity of electromagnets with intermittent control electromagnetism to basically meet the production needs and play the role of quantitative feeding. I plant 3 to 15 tons cupola used this quantitative feeding method, the effect is very good. The work shown in Figure 1.
