Induction Furnace Voltage

Induction Furnace Voltage The induced voltage of the intermediate frequency furnace often exists on the inductor coil, the furnace mouth plate, the water-cooled guide rail, and the furnace body bracket. So, what is the reason for the induction voltage of the induction furnace? Next, we will talk about the induced voltage of the intermediate frequency furnace. When the induction coil of the intermediate frequency furnace is working, when an alternating current passes through the coil, an alternating magnetic field is established in the space around the coil. An induced electromotive force is generated in the metal blank in the alternating magnetic field. We often regard the blank as a closed circuit with only one turn of the coil. When the induced electromotive force is generated, an alternating self-circulating circulating current—eddy current is generated in the circuit. Induction heating is to use the heat energy generated by this eddy current to heat the metal blank. The water-cool...

Troubleshooting of Medium Frequency Furnace

Troubleshooting of Medium Frequency Furnace This article introduces the faults and solutions of medium frequency furnace. 1. Fault phenomenon: large DC current, low DC voltage, and if the voltage, dull equipment sound, over-current protection. Analysis and treatment: the thyristor with one arm of the inverter bridge may be short-circuited or open-circuited, resulting in the operation of the three-arm inverter bridge. Use an oscilloscope to observe the voltage drop waveform of the thyristor on the four bridge arms of the inverter bridge. If the voltage drop waveform of the thyristor on one bridge arm is a line, the thyristor has been through; if it is a sine wave, the thyristor has not been through. Replace the through thyristor; find out the reason why the thyristor is not turned on. 2. Fault phenomenon: when the heavy load cold furnace is started, all electrical parameters and sounds are normal, but the power cannot be raised, and overcurrent protection. Analysis and ...
