塞棒控制自动拉钢控制系统在R9米连铸机的应用

摘要

石横特钢二炼钢车间现有四机四流 R9米连铸机一座，优钢的开发和生产全靠塞棒控制系统提供稳定的液面及恒拉速，从而保证钢水形成钢坯的质量，对提高铸坯质量起到一定的作用，在目前工业自动控制系统中，可编程逻辑微处理器（SC3000- PID）、探测器（HN- DET- D51/290- M2）、驱动器（SCDK- S5）作为常用的成熟现场控制设备，上位机作为数据采集系统已经得到广泛使用。通过检测液面，传输到微处理器进行换算， PLC模块控制驱动器直接控制电动缸微动作，实现闭环控制，从而得到高精度的钢水液面。%There is four machine four flow meters caster R9 in Stone Cross Steel no . 2 steelmaking workshop . The development and production of superior steel depend on steady liquid level control sys-tem and constant speed provided by stopper rod control system , so as to guarantee the quality of formed steel billet and play a role to im-prove casting quality . In current industrial automatic control system , programmable logic microprocessor (SC3000 - PID), detector (HN -DET - D51/290 - M2), driver (SCDK - S5) are commonly used as mature field control equipment , and PC as the data acquisition system has been widely used . By detecting liquid level and transmitting to the microprocessor for conversion , PLC module control drive directly con-trols electric cylinder micro motion , achieves closed-loop control , so as to get high precision of liquid steel surface .
