基于PLC的重型H型钢连铸坯火焰切割系统设计

Design of Flame Cutting System for Heavy H-beam Continuous Casting Billet Based on PLC

为解决大型钢铁企业对连续重型H型热坯切断的生产需求,设计一种基于可编程逻辑控制器的重型H型钢连铸坯火焰切割生产系统。该系统以西门子S7-1500PLC为控制核心,火焰切割机为执行机构,采用红外摄像定尺技术测量切割长度,使用Wincc7.4设计上位机画面对整条生产线进行实时的监测和控制,实现了对连续异形坯的自动切割,具有较高的切割控制水平和尺寸测量精度。

In order to meet the production demand of continuous heavy H-shaped hot billet cutting by large steel enterprises,a heavy H-shaped steel continuous casting billet flame cutting production system based on programmable logic controller was designed.With Siemens S7-1500 PLC as the control core and flame cutting machine as the actuator of the system,infrared camera was used to measure cutting length,and Wincc7.4 was adoted to design upper computer screen to monitor and control the entire production line in real time.With the system,the automatic cutting of continuous special-shaped blanks was realized with high level of cutting control and high accuracy of dimensional measurement.
