Temperature control of steel plate induction heating equipment

Working principle of temperature control

The temperature control principle of steel plate induction hardening machine is based on feedback control system. The temperature sensor monitors the temperature of the workpiece in real time and transmits the signal to the temperature controller. The thermostat adjusts the heating power or cooling rate based on the difference between the set target temperature and the actual temperature to maintain the workpiece within the desired temperature range.

Temperature control is the core technology of steel plate induction heating furnace , which directly affects the accuracy, efficiency, and final product quality of the heating process. Accurate temperature control can ensure that the workpiece reaches the expected temperature distribution during the heating process, thereby achieving ideal heat treatment effects or processing requirements.

Composition of temperature control system

The temperature control system of steel plate induction hardening equipment usually consists of the following parts:

Temperature sensor:

Thermocouple: commonly used to directly measure the temperature on the surface or inside of workpieces, suitable for high temperature conditions.

Infrared thermometer: a non-contact measuring device that determines temperature by detecting the infrared energy emitted by the workpiece, suitable for difficult to contact high-temperature workpieces or moving workpieces.

thermostat:

The thermostat receives signals from the temperature sensor and compares them with the preset target temperature. If the detected temperature deviates significantly from the set value, the thermostat will adjust the heating power or heating time to ensure that the temperature remains within the set range.

Heating power adjustment device:

Inverter: By changing the power frequency to regulate the heating power, the rate of temperature rise and fall can be controlled. Power control module: It can accurately adjust the heating current to precisely control the temperature during the heating process. Cooling system:

Temperature control not only includes the heating part, but also involves the cooling process. After reaching the set temperature, the cooling system (such as water-cooled or air-cooled) promptly removes excess heat to prevent overheating.
