Induction melting inject new vitality for casting production

Medium frequency induction furnace is the main equipment in the foundry, stability, reliability and security of its work is flow process of casting production line ensure normal and stable work. At present, the induction melting furnace has been developed rapidly, has gradually replaced the cupola.
Induction furnace except to smelting in the atmosphere, can also in a vacuum and argon and helium protection atmosphere such as smelting, to meet the requirements of special quality. Compared with other melting furnace, in addition to the melting principle, have the following features:
(1) using electromagnetic induction heat the material directly, high thermal efficiency.
(2) due to the melting is not used in the air, burning less elements, less impurities mixed with.
(3) the operation is simple, composition adjustment, easy to add trace elements and temperature control.
(4) around the furnace heat and less smoke generates low, improve the working environment, good for the environment protection.
(5) cover an area of an area small.
(6) current density is high, suitable for high temperature melting.
(7) easy to realize automatic control, especially can use computer to process control.
(8) frequency magnetic field of molten metal has magnetic stirring effect, beneficial ingredients evenly, and dross, uniform composition and temperature of liquid metal.
The application of the induction heating technology in China, originated in the 1950 s, the technique of inductive heating almost entirely from the former Soviet union and the Czech republic and other countries, is mainly used in machine tools, textile machinery, automobile, tractor and other manufacturing industries. Induction heating power supply amount applied to industrial production is in the 1980 s.
