一、概况遵照毛主席关于“我们必须打破常规,尽量采用先进技术”的伟大教导,在上级党组织的正确领导下和江苏省计算技术研究所,天津电气传动设计研究所等单位的大力支持下,于七一年,我车间在3~#高炉(255M~3)上料系统的程序系统和布料器上开始采用锗管无触点控制;七二年初1~#高炉(300M~3)大修时,又将程序系统改为锗管无触点控制;这两套无触点装置都使用+12V10A 和-12V10A 锗管稳压电源各一台,控制系统主要由天津电气传动研究所设计的LB1型逻辑元件、开关放大器等140多只及二极管附件等所组成。投
I. General Situation Following the great teachings of Chairman Mao on “We must break the routine and try our best to adopt advanced technology”, under the correct leadership of the superior party organizations and with the strong support from the Institute of Computing Technology of Jiangsu Province and Tianjin Electric Drive Design Institute , In 1981, my workshop began to adopt the germanium tube non-contact control on the system of the feeding system of the 3 ~ # blast furnace (255M ~ 3) and the cloth distributor. In the beginning of 1972, blast furnace (300M ~ 3) overhaul , The program system again to germanium tube non-contact control; these two sets of non-contact devices are used + 12V10A and -12V10A germanium tube power supply each one, the control system is mainly designed by Tianjin Electric Drive Institute LB1 More than 140 logic amplifiers, switching amplifiers and diode accessories. cast
