The control system of a steel bar heating furnace is mainly composed of several commonly used instruments and meters. These instruments and meters not only measure the important parameters of the furnace, but also help to control the temperature of the furnace.
1、Temperature controller：
Temperature controllers are widely used in the heating furnace control system. It is mainly used to control the temperature of the furnace and to detect the total heat of the furnace. Temperature controllers are typically composed of two parts: a temperature measuring element, such as a thermocouple; and a signal processing unit, such as a microprocessor. The signal processing unit receives the signal from the temperature measuring element, then processes it and turns it into a signal that can be used to control the furnace temperature. In addition, when the temperature exceeds the set value, it will send out an alarm signal.
2、Pressure Detector：
Pressure detectors are also important instruments in the furnace control system. It is mainly used to measure the pressure of the furnace and the pressure of the combustible gas. According to the pressure change, the alarm signal will be sent out if the pressure is too high or too low.
3、Flow Meter：
Flow meters are an important instrument used in furnace control systems. It is mainly used to measure the air flow rate of the furnace, the fuel flow rate and other parameters. In addition, it can also display the data in real time on the display screen and give an alarm when the flow rate is out of the set range.
4、Vibration Detector：
Vibration detectors are also important for furnace control systems. It is mainly used to measure the vibration intensity of the furnace, and can detect whether the furnace is running normally or not.
5、Gauge：
Gauges are used to measure the pressure of the furnace in furnace control systems. It is mainly used to detect the pressure of the furnace oil.
In addition to the above instruments and meters, there are still many instruments and meters used in the control system of a steel bar heating furnace. Such as thermal protection, frequency converter, temperature recorder and so on. All these instruments and meters play an important role in the safety and efficiency of a steel bar heating furnace.
