Series one to two medium frequency induction furnace
The series one to two intermediate frequency induction furnace has high power factor and saves energy. The operating frequency range of 150 to 10,000 Hz induction furnace called medium frequency induction furnace, mainly in the frequency range 150 to 2500 hertz. The medium frequency induction furnace is a special equipment suitable for smelting various metals such as steel, copper, aluminum, silver, alloy, etc., and has the following advantages:
1. Fast melting speed and high production efficiency. Medium frequency induction furnace power density, power per ton of molten steel is disposed about a 20 to 30% large than the other induction furnace. Therefore, under the same conditions, the medium frequency induction furnace has a high melting speed and high production efficiency.
2 , adaptability, flexible use. In the medium frequency induction furnace, the molten steel can be completely cleaned, and it is convenient to replace the steel.
3 , electromagnetic stirring effect is better. Since the electromagnetic force of the molten steel is inversely proportional to the square root of the power supply frequency, the stirring power of the intermediate frequency power supply is smaller than that of the commercial frequency power supply. For the removal of impurities and uniform chemical composition in steel, uniform temperature, the stirring effect of the intermediate frequency power supply is better.
4 , easy to start and operate. Since the skin effect of the intermediate frequency current is much larger than the power frequency current flow, the medium frequency induction furnace has no special requirements for the charge when starting, and can be heated quickly after charging; therefore, the intermediate frequency induction furnace is mostly used under the condition of periodic operation. . Another advantage of easy start-up is that it saves power during cycle operations.
Due to the above advantages, the medium frequency induction furnace has not only been widely used in the production of steel and alloys in recent years, but also in the production of cast iron, especially in the casting workshop of the cycle operation.
