失重秤控制系统的改造及应用
|
摘要
金隆公司闪速炉精矿投入计量采用的是全套引进铜精矿失重计量设备,该设备的在线监视、控制和操作原由一套WB930控制系统实现。2015年该公司对失重控制系统进行优化改良,将其替换为PLC控制系统。改造后,可视化功能增强,流态化抑制功能得以实现,适合FF工况,使闪速炉运行更加稳定。
The imported copper concentrate weight-loss metering equipment is used in the flash furnace concentrate input measurement of Jinlong Company. The on-line monitoring, control and operation of the equipment are originally realized by a set of WB930 control system. The company optimized and improved the loss-in-weight control system and replaced it with PLC control system in 2015. After the modification, the visualization function is enhanced and the fluidization suppression function is realized,which is suitable for FF working condition and makes the flash furnace run more stable.
