The induction heating equipment uses medium frequency online metal induction heating equipment to replace the traditional reheating furnace for secondary heating of steel pipe. Metal induction heating equipment adopts two advanced computer network control, namely: basic automation and process control. Let's learn about induction heating equipment!
Induction heating equipment is a kind of three-phase power frequency alternating current, which is converted into direct current after rectification, and then the direct current is converted into adjustable current to supply the alternating current flowing through the capacitor and induction coil. High density magnetic lines of force are generated in the induction coil of induction heating equipment, and the metal materials in the induction coil are cut, resulting in large eddy current in the metal materials. The induction heating equipment puts a metal cylinder in the induction coil with alternating medium frequency current. The metal cylinder does not directly contact with the induction coil. The temperature of the coil itself is very low, but the surface of the cylinder is heated to reddening or even melting. Moreover, the speed of reddening and melting can be achieved by adjusting the frequency and the strength of the current. If the cylinder of induction heating equipment is placed on the coil, then the temperature around the cylinder is the same, and the cylinder heating and melting does not produce harmful gas and strong light pollution to the environment.
Application of induction heating equipment:
Induction heating equipment is mainly used for smelting steel, iron, copper, aluminum and alloy. It has the characteristics of high melting efficiency, good power saving effect, uniform metal composition, less burning loss, fast temperature rise and easy temperature control. It is suitable for various metal smelting occasions.
Features of induction heating equipment:
The induction heating equipment has constant power output, faster melting speed and more obvious power saving effect. Induction heating equipment zero pressure sweep frequency software start, can adapt to the requirements of frequent start. Comprehensive protection measures for induction heating equipment, such as over-current, over-voltage, current limit, pressure limit, water shortage, lack of protection, ensure the reliable operation of the equipment under the premise of ensuring the smelting speed. The induction heating equipment is easy to operate and suitable for various casting processes.
