摘　　要： 介绍了弧形连铸机塞棒自动开浇与液位自动控制系统,该系统采用SiemensS7-400PLC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,利用差值控制塞棒运动,实现全自动浇钢,从而提高铸坯质量,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 liquid level control system of arc continuous steel caster is introduced. The Siemens S7-400PLC is used as the first-level automatic facility. Artificial casting process is imitated and the five actions are set during the auto casting. These parameters are also optimized in the process of pilot production. PLC receives the information of liquid level and compares the difference between the measured values and given values to control the movement of stopper. Consequently, fulfill the auto continuous casting and improve the product quality, and provide the reference for the improvement of those existing old continuous casters and the design of new caster.
