    Industrial electric furnace technical information

    Safe use of the core components of the intermediate frequency furnace

    The thyristor is the core of the IF power supply, and its accurate use is critical to the operation of the equipment. It is normal for a medium-frequency furnace to damage a few thyristors in one year. If the thyristor is burned frequently and the intermediate frequency furnace is shut down, affecting the production, it is necessary to be alert. The operating current of the thyristor ranges from a few hundred amps to several thousand amps, and the voltage is usually one to two kilovolts. Good main control board protection and good water cooling conditions are necessary.

    Overload characteristics of thyristors: Damage to thyristors is called breakdown. Under normal water cooling conditions, the current overload capacity can reach more than 110%; no voltage overload capacity, that is, the thyristor is definitely damaged under overpressure conditions. Taking into account the surge voltage, manufacturers often choose thyristor components at 3-4 times the operating voltage when manufacturing facilities.

    The exact installation pressure of the thyristor: 150-200KG/cm2. When the facility is shipped from the factory, it is usually press-fitted with a hydraulic press. Manual use of ordinary wrenches can not reach this value with maximum strength. Therefore, when manually pressing, there is no need to worry that the thyristor will be crushed; if it is loosened, it will burn the thyristor due to poor heat dissipation.

    SCR radiator structure: water-cooled cavity + multi-copper column support. If the circulating water is too hard, it will foul inside the water chamber, causing poor heat dissipation; if the water chamber enters the leaves and other debris, it will also cause poor water flow.
