Induction Furnace Disadvantages

In the past 30 years, the application of induction furnaces in the steel casting industry has developed rapidly, of course, because it has many advantages, but on the other hand, it also has many disadvantages. When choosing it as smelting equipment, it is necessary to carry out comprehensive analysis and research, strives to maximize its strengths and avoid its weaknesses, and must not join in the fun and follow the trend. After the equipment is selected, you should have a comprehensive understanding of its characteristics, and strive to continuously improve the quality of casting products on the basis of energy saving and emission reduction.

Advantages and disadvantages of induction furnace

Advantages of induction furnace

1) Compared with a fuel furnace, it is easy to get high temperatures.

2) It can be heated from the inside of the material to make it warm up.

3) Easy to use in controlled atmosphere furnaces and vacuum furnaces.

4) The electric furnace has no heat loss from the exhaust smoke of the fuel furnace, so the thermal efficiency is high.

5) It is easy to control the temperature, and it is convenient for remote control and fine adjustment.

6) Capable of rapid heating.

7) Good operating performance, no pollution to the environment.

Disadvantages of induction furnace

1) Need to increase the cost of power distribution equipment.

2) High electricity cost.

3) When the resistance heating temperature exceeds 1000 °C, the refractory material may conduct electricity, and insulation problems need to be paid attention to.

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 ...
