矿用圆环链淬火温度控制系统

矿用圆环链的热处理是决定其产品质量和生产效率的关键所在. 但由于控制方法和稳定性等原因，目前国内矿用圆环链热处理中所使用的中频感应加热系统往往达不到工艺要求. 本设计在对淬火工艺进行深入分析后确定了高质量圆环链淬火前最合理的温度. 通过非接触式红外测温传感器对圆环链的淬火温度进行实时检测，结合积分分离PID算法，以PLC为控制核心，利用D/A模块对中频电源控制模块进行控制，A/D模块对系统反馈量进行采集，并通过触摸屏对系统参数进行设置. 最终实现对淬火过程的高精度闭环控制. 针对工业现场的复杂环境进行了系统控制温度的稳定性分析，从实际投入使用结果来看该系统对中频感应加热设备温度控制精度较高且操作简单方便，人机界面友好，长期运行稳定可靠.

Mining Round Link Chain of Quenching Temperature Control

Heat treatment of mining round link chainis is the key to the product quality and production efficiency. But because the control method and stability and other reasons, the medium frequency induction heating system used at presentdomestic chain in mining circular heat treatment often do not meet process requirements. The design determines the high quality chain before quenchingthe most reasonable temperature in deep analysis on the quenching process. The non-contact infrared sensor quenching temperature on the chain for real-time detection, integral separation PID algorithm, using PLC as the control core, control of the intermediate frequency power supply control module uses the D/A module, A/D module to collect feedback of the system, and through the touch screen to set the parameters of the system. The final realization of high precisionto is the closed-loop control of quenching process. In view of the complex environment of the industrial site stability analysis of the temperature control system, from the actual results of the system was put into use in intermediate frequency induction heating equipment temperature control accuracy is high and the operation is simple and convenient, friendly man-machine interface, the long-term stable and reliable operation.
