摘　　要： 弧形连铸机塞棒自动开浇与液位自动控制系统采用Siemens S7-400PLC作为基础自动化设备,模仿人工开浇过程,设定自动开浇的5步动作,并通过生产试验优化了开浇参数。液位调节时,PLC将检测到的液位信号与设定值比较,通过变增益控制器利用差值来控制塞棒运动,以实现全自动浇钢。从而提高了铸坯质量,并为改造中国现有连铸机和设计现代化新铸机提供依据。 The stopper auto casting and mould level control system of arc continuous caster is introduced. Siemens ST-400PLC are used as first-level automatic facility. Artificial casting process is imitated and the five actions are executed during auto casting. These parameters are optimized in process of pilot production. PLC receives the in formation of liquid level and compares the measured values and given values to control the movement of stopper. In this way, auto continuous casting is fulfilled and product quality is improved. Some beneficial experiences are giv- en for the improvement of present old continuous casters and design of new caster.
