分析了连铸生产基本工艺和液面加压控制的基本方案,从PLC组成及控制、涡流检测两个方面对控制系统的硬件进行分析。根据控制方案和要求,对液面模糊PID控制流程进行设计,实现连铸的稳定。
The basic scheme of continuous casting production process and liquid pressure control is analyzed. The hardware of control system is analyzed from two aspects of PLC composition and control and eddy current testing. According to the control scheme and requirements, the liquid level fuzzy PID control process is designed to achieve the stability of continuous casting.
