620m~3高炉的PLC-115u可编程控制系统,通过对270个开关量的控制,实现主卷扬系统周期料批、布料角度、料线及料钟的自动控制。并用工业控制机DJS—0415自动按照上料顺序记录并打印出入炉烧结矿、焦炭的实际称量值,对每批(车)人炉量称量值及时给予自动补偿和累计计算。消除了原机械称量装置线性差、标校周期短、精度难掌握等原因而造成称量不准引起炉温波动等弊病。正式
620m ~ 3 blast furnace PLC-115u programmable control system, through the control of 270 switches, the realization of the main winch system cycle batch material, cloth angle, material and material clock automatic control. And industrial control machine DJS-0415 automatically according to the order of loading and printing out of the furnace sintering ore, coke actual weighing value, for each batch (car) people weighing value in a timely manner to give automatic compensation and cumulative calculation. Elimination of the original mechanical weighing device linearity poor, standard calibration cycle is short, accuracy is difficult to grasp and other reasons caused by weighing temperature is not allowed to cause fluctuations and other ills. formal
