Application of PLC in Induction Heating Equipment

Application of PLC in Induction Heating Equipment

PLC intelligent programmable controllers have been widely used in the field of industrial control due to their simplicity, reliability, and ease of control. In the medium frequency induction heating industry, with the improvement of automation and the increase of automatic production lines, PLC is being increasingly applied in this industry.

The electrical control function system mainly consists of three parts: intermediate frequency induction heating power supply, sensors, and PLC controller cabinet. Medium frequency power supply is a device that converts three-phase AC power into single-phase AC power; The sensor is the main body that heats the workpiece. Various display operation buttons and process displays are installed on the PLC controller cabinet. The main functions are as follows:

(1) The rhythm controller is a production rhythm determined by productivity, and for each rhythm, the feeding cylinder pushes a piece of material towards the sensor. The rhythm of this system is 30S;

(2) The manual automatic conversion function debugging and fault maintenance should be in manual working mode, and should work in automatic mode normally;

(3) The pre stop function system is for sequential feeding control;

(4) The emergency stop function is equipped with emergency stop buttons on both the power cabinet and control cabinet. When an emergency fault occurs, the entire line will stop working unconditionally;

(5) When the device malfunctions, the reset function first triggers an audible and visual alarm. After troubleshooting, the reset button must be pressed to restart the system; (6) The protection function system is designed with various protections, mainly including water pressure protection, phase failure protection, and over temperature protection.
