    Electric furnace technical information

    1)     Rugged and elegant, especially for large-capacity furnaces, it requires a strong rigid structure. From the safety point of the tilting furnace, try to use steel shell intermediate frequency furnace .

    2)     The yoke made of silicon steel sheet shields and emits magnetic lines of force generated by the induction coil, reduces magnetic leakage, improves thermal efficiency, increases production, and saves energy by about 5%-8% .

    3)     The presence of the furnace cover reduces heat loss and increases the safety of the equipment.

    4)     Long service life, steel shell medium frequency furnace due to less magnetic leakage, equipment life is much higher than aluminum shell furnace. The normal service life is generally more than 10 years.

    5)     IF steel furnace safety performance much better than the aluminum furnace, aluminum melting furnace in the time due to high temperature, weight, aluminum is easily deformed, poor security. The steel shell intermediate frequency furnace uses a hydraulic tilting furnace, which is safe and reliable.

    5. What are the main uses of steel shell intermediate frequency furnaces ?

    IF steel melting furnace is mainly applied to steel, iron, copper, aluminum and alloys, having a high melting efficiency, energy-saving effect, a uniform metal composition, burning small, quick temperature rise, easy to control temperature, etc., suitable for all melting metals.

    6. What is the role of the yoke in the steel shell intermediate frequency furnace ?

    The yoke is a yoke made of a stack of silicon steel sheets. It is uniformly and symmetrically divided around the induction coil. Its function is to constrain the magnetic flux leakage of the induction coil to improve the efficiency of the induction and increase the magnetic shielding. The heat generation of metal members such as the hob also serves to reinforce the inductor.

      The steel shell medium frequency furnace body has a built-in yoke, and the yoke shield can reduce the magnetic flux leakage, prevent the furnace body from heating and improve the efficiency. At the same time, the yoke acts as a support for fixing the induction coil, so that the furnace body achieves high strength and low noise.

    Seven, intermediate frequency furnace steel yoke temperature is too high what is the reason?

    The yoke redness is a common failure phenomenon in the operation of the intermediate frequency power supply. First check if there is any problem with the cooling water system, check whether the red yoke inlet and outlet water is normal, and whether the pipeline is aging or leaking. If it is normal, check the following aspects.

    (1) The yoke of the intermediate frequency power supply is aging, and the interlayer insulating coating is severely corroded. For this, the silicon steel sheet can be opened for surface coating treatment.

    (2) The yoke is adhered to the molten steel (iron filings), and the yoke can be polished to remove the adhered iron filings.

    (3) Check the thickness of the bottom of the furnace. If the bottom of the furnace is too thick, it will cause the yoke to heat up and become red.

    (4) The temperature of the circulating water inlet water is too high, and the water temperature inside the yoke circulation system is too high to generate gas. Since the gas cannot be discharged, the circulating water cannot circulate, causing the temperature to rise.

    ( 5 ) The circulating water pressure becomes smaller, or after the waterway is changed, the waterway becomes more or the water pipe becomes larger, and the water flow of the other circuits becomes larger, causing the yoke water flow to become smaller.
