What is an intermediate frequency heating furnace What are the advantages of a steel pipe intermediate frequency heating furnace

At present, many metallurgical casting enterprises in China are using intermediate frequency heating furnaces, which can greatly improve work efficiency. Next, Kehua will take you to understand what is an intermediate frequency heating furnace and what are the advantages of a steel pipe intermediate frequency heating furnace? What is an intermediate frequency heating furnace 300HZ or above to 20K HZ) power supply device, this eddy current also has some properties of intermediate frequency current, that is, the free electrons of the metal itself flow in the metal body with resistance to generate heat. For example, if a metal cylinder is placed in an induction coil with alternating intermediate frequency current, the metal cylinder is not in direct contact with the induction coil. Melting, and the speed of this redness and melting can be achieved as long as the frequency and the strength of the current are adjusted. Steel pipe intermediate frequency heating furnace What are the advantages of steel pipe intermediate frequency heating furnace? Convert the direct current into an adjustable intermediate frequency current, supply the intermediate frequency alternating current flowing through the capacitor and the induction coil, generate high-density magnetic lines of force in the induction coil, and cut the metal material contained in the induction coil, in the metal material Generates a large eddy current. Due to the fast heating rate of this heating method, there is very little oxidation. The oxidation burning loss of the intermediate frequency heating forging is only 0.5%, the oxidation burning loss of the gas furnace heating is 2%, and the coal burning furnace reaches 3%. Compared with a coal-fired furnace, a ton of forgings can save at least 20-50 kilograms of steel raw materials. After reading Kehua's introduction, everyone must already know what an intermediate frequency heating furnace is. The biggest advantage of the steel pipe intermediate frequency heating furnace is that the heating speed is fast, which can greatly improve the work efficiency.
