Principle of temperature closed-loop control system for 1 ton intermediate frequency heating furnace
By the company developed the KX-2010 tons IF furnace temperature type 1 loop control system closed loop temperature control board is designed with a control interface, an intermediate frequency used in Japan conductive furnace temperature controller with PID regulator SR93 meter, far infrared fiber optic temperature The instrument uses a femtosecond TW series thermometer, measuring temperature 0-1500 °C.Firstly, the heating temperature is set in the temperature control instrument. After the power is turned on, the thermometer measures the heating temperature in real time and feeds back to the temperature control instrument. The temperature control instrument compares the measured temperature with the set heating temperature and outputs an analog signal to the intermediate frequency main control board. The main control board automatically adjusts the thyristor firing angle according to the level of the signal, so that the power output power is adjusted according to the level of the analog signal, and the temperature closed-loop control is achieved. Because the temperature measurement system uses the imported steel special thermometer, the temperature measurement is accurate. Optical fiber signal transmission ensures the stability of the collapse control, which is realized by online automation. The user-friendly design of the temperature control table operation interface is convenient for adjustment and easy to observe. The entire system is highly automated and responsive, designed for steel testing.
