一、概述 攀钢2~#高炉容积为1200m~3,自1971年投产以来,为了提高上料系统的可靠性,先后进行了多次改造。上料系统的控制由继电器、半导体集成电路发展到计算机。1986年8月初,我们又对2~#高炉上料系统作了进一步的改造,采用可编程序控制器(PC)对上料系统进行自动控制,于1986年8月底投入使用,整个系统的可靠性有了较大的改善。
I. Overview Pangang 2 ~ # blast furnace capacity of 1200m ~ 3, put into operation since 1971, in order to improve the reliability of feeding system, has carried out a number of transformation. Feeding system control from the relay, the development of semiconductor integrated circuits to the computer. At the beginning of August, 1986, we made some further reformation on the feeding system of blast furnace 2 ~ #, using the programmable logic controller (PC) to control the feeding system automatically and put it into use at the end of August 1986, the whole system is reliable Sex has been greatly improved.
