What is the application of IF power supply in the industrial field?
2, in the application of heat: the workpiece in the heating process, the overall heating of the metal, the workpiece can reach a temperature range inside and outside. Also used in the casting of metal materials, stamping, extrusion, rolling and other heating before processing.
As the IF furnace heating time is short, almost no heating or only a small amount of oxide, so the weight loss caused by the scale of less than 0.5%, while the gas furnace oxide damage caused by weight loss of up to 20%, coupled with the loss of pickling, waste is very big. So the use of IF power, can greatly improve efficiency, and easy maintenance, reduce labor intensity, easy to achieve automation.
Induction heating, due to the high frequency of the skin effect, the density of the induced current is gradually reduced from the surface to the inside. The same material, the higher the frequency, the current density from the outside to the inside to reduce the faster.
4, the application of welding: IF power can be used for welding, with welding speed, the impact of small heat around, no pickling to remove the advantages of scale. Can also be used after welding should be added (tempering), can greatly improve work efficiency.
IF power supply is widely used, some applications are being developed, with the development of thyristor technology and IF power applications continue to accumulate experience, the thyristor IF power supply will have a broader development prospects.
3, in the application of heat treatment, the use of IF current skin effect to improve the mechanical properties of steel, it has a high hardness and fatigue resistance, the steel is concerned, the heating frequency due to the diameter of the pipe, When the thickness of a thin wall, the smaller the diameter of the pipe, the higher the frequency of induction heating.
Quenching load characteristics: the load changes little, overcurrent over-voltage less chance, but the start is very frequent, short operating cycle.
1, smelting furnace metal smelting: This is one of the most widely used aspects of the development of China's thyristor power, began in the smelting, melting all kinds of carbon steel, alloy steel, alloy cast iron, copper and aluminum can also be, and Used to extract high purity zinc and other non-ferrous metals. Smelting load is the worst load of medium frequency power supply, yin anti-change is large, the load is unstable, but the intermediate frequency power supply can be very ideal to complete this task, the most prominent advantage is to save energy, every smelting IT steel power consumption around 500KW.h. Also easy to start, smooth steel, eddy water mixing small, good quality smelting.
