在毛主席“鞍钢宪法”的指引下,兰州铁路配件厂闸瓦铸造自动线于73年建成并投入试生产。该自动线控制系统采用了射流控制。通过半年多试生产发现射流控制系流故障较多,影响自动线正常运行。74年我们通过射流短训班并与兰大同志一起对该控制系统作了改进,运行三年多来效果良好,提高了运转的稳定性和劳动生产率。 一、射流控制线路在设计方面的改进 全自动线有六个射流控制台,分别控制全线九台机械设备,如图1所示。
Under Chairman Mao’s “Anshan Iron and Steel Constitution,” Lanzhou Railway Parts Factory brake tile casting automatic line was completed in 73 and put into trial production. The automatic line control system uses a jet control. After more than six months of trial production, it was found that there are many faults in the jet flow control system, affecting the normal operation of the automatic line. In the year of 74, we improved our control system by jetting a short course and working with Comrade Lan, running well for more than three years and improving the stability of operation and labor productivity. First, the jet control circuit in the design of improvements Fully automatic line has six jet console, respectively, to control nine machines across the board, shown in Figure 1.
