The automation control system of IF furnace mainly consists of two parts: hardware system and software system. The hardware system mainly includes sensors, actuators, controllers and so on, which are used to collect parameters such as temperature, power and current in the heating process, and realize the regulation and control of heating power through the controller.
I. Overview of automation control system
The automation control system of IF furnace is mainly composed of two parts: hardware system and software system. The hardware system mainly includes sensors, actuators, controllers and so on, which are used to collect parameters such as temperature, power and current in the heating process, and realize the regulation and control of heating power through the controller. And the software system refers to the control program of the automatic control system, which includes the setting of the heating process parameters, the establishment and optimization of the control model, data acquisition and analysis, and other functions.
Second, the sensor module
The automation control system of IF furnace firstly needs to collect various process parameters and convert them into numerical signals to be sent to the controller for processing. In order to achieve this function, the system needs to install various types of sensors, including temperature sensors, current sensors, power sensors and so on.
Among them, temperature sensors are ZUI common type of sensors, commonly used to measure the temperature of metal materials. There are mainly thermocouple, RTD and IR thermometer types, which are installed inside and outside the furnace to measure the temperature of the surface of the workpiece. By collecting temperature data from various locations, the automated control system can achieve precise regulation of the heating power and prevent problems such as overheating or uneven temperature during the heating process.
The current sensor is mainly used to measure the current of the workpiece and is usually installed in the induction coil to monitor the magnitude and direction of the current. The current data collected can help the control system determine whether the heating power reaches the preset value, and adjust and control the heating power according to the real-time data.
The power sensor is used to measure the output power of the IF furnace and is usually installed at the output port of the IF power supply. By monitoring the output power and comparing it with the preset value, the automation control system can adjust and control the heating power according to the actual situation.
Third, the actuator module
Actuator module mainly refers to the equipment that controls the heating power of IF furnace, which mainly includes IF power supply, induction coil and so on. By controlling the output voltage and frequency of the power supply, as well as the size and position of the control coil and other parameters, the precise control of the heating power can be realized.
Medium frequency power supply is the ZUI important actuator in the automatic control system of medium frequency furnace, which is mainly used to control the heating power in the process of induction heating. Its control principle is to control the size and direction of the magnetic field generated in the induction coil by changing the voltage and frequency of the power output, so as to realize the precise heating of the workpiece.
The induction coil is also one of the important actuators in the automatic control system of the medium frequency furnace, mainly used to generate the heating magnetic field. By changing the size and position of the coil, the size and position of the magnetic field can be controlled so as to achieve precise heating of the workpiece.
Four, controller module
The controller module is the core component in the automatic control system of medium frequency furnace, which is mainly responsible for receiving the data collected by the sensors and sending control signals to the actuators after processing by the control model to realize the precise control of heating power.
The controller module includes two parts: controller and computer. The controller is mainly responsible for collecting and processing the sensor signals, while the computer is responsible for writing and running the automation control program.
The controller usually adopts PID control algorithm to realize the control of heating power, which is an error feedback based control method that can regulate and control the heating power according to the real-time data collected and the parameters set by the user. At the same time, the controller can also adjust and optimize the control model according to the real-time data to achieve more accurate control results.
The computer is responsible for writing and running the automated control program, including the user interface, control algorithms and other elements. By writing the control program, precise control and monitoring of the heating process can be realized, and the heating process parameters can be adjusted and optimized to achieve the ZUI best heating effect.
To sum up, the automatic control system of medium frequency furnace mainly consists of sensors, actuators, controllers and computers, etc. It can realize the precise control and monitoring of heating power, improve the automation of heating process, and provide strong technical support for enterprises to improve production efficiency, ensure product quality and reduce manual operation.
