What are the applications of intermediate frequency power supply in industrial field?
In the application of heating the workpiece in the heating process, heating of the metal, the workpiece can be reached inside and outside a temperature range. The utility model is also used for heating, casting, stamping, extruding, rolling, etc. of metal materials before processing.Because if furnace short heating time, heating almost no or only a small amount of oxide skin, so the skin caused by oxidation of weight loss is less than 0.5%, while the oxide gas caused by weight loss is as high as 20%, coupled with the loss and waste pickling is great. Therefore, the use of medium frequency power supply can greatly improve efficiency, and easy maintenance, reduce labor intensity, and facilitate the realization of automation.Due to the high skin effect, the density of the induced current decreases gradually from the surface to the interior. With the same material, the higher the frequency, the faster the current density drops from the outer surface to the interior.
Application in welding: intermediate frequency power supply can be used for welding, with fast welding speed, little influence on the surrounding heat, no pickling to remove the advantages of oxidation skin. The utility model can also be used for the after welding and adding (tempering) aspects, so as to greatly improve the work efficiency.The application of intermediate frequency power supply is widespread, and some applications are being developed. With the development of thyristor technology and the continuous accumulation of application experience of intermediate frequency power supply, thyristor medium frequency power supply will have a broader prospect of development
In the application of heat treatment, to improve the mechanical properties of steel by the skin effect of intermediate frequency current. It has high hardness and fatigue resistance of steel pipe, heating frequency, because of thick walled pipe diameter, pipe when the pipe diameter is smaller, the frequency of induction heating the higher.Characteristics of quenching load: little change in load, less over flow and over voltage, but very frequent start-up and short operation cycle.
Metal smelting furnace smelting: This is one of the most widely used in the development of our country, the thyristor power supply can be started in the smelting, smelting various carbon steel, alloy steel, cast iron, alloy, copper and aluminum can, as well as for the refining of high purity zinc and other non-ferrous metals. Melting is the worst load load of intermediate frequency power supply, high anti Yin changes, load is not stable, but if power can be very ideal to complete this task, is the most prominent advantages of energy saving, power consumption in each smelting IT steel 500KW.h. In addition, the utility model has the advantages of convenient starting, stable steel level, low eddy current agitation and good smelting quality.
