Application Range of Medium Frequency Induction Furnace

  Application Range of Medium Frequency Induction Furnace (1) Intermediate frequency induction furnace is used for forging and rolling 1. Wheel forgings, ring forgings, shaft forgings, cylinder forgings, gear forgings, stainless steel forgings, and large flanges. 2. Hot heading of standard parts and fasteners, such as heating for tempering, forging, and extrusion of high tools. 4. Quenching and tempering of bar materials (2) Intermediate frequency induction furnaces are used for smelting 　 Including the smelting of steel, gold, silver, copper, and aluminum, especially in the foundry industry (3) Intermediate frequency induction furnace is used for heat treatment 1. Heat treatment of various hardware tools and hand tools. Such as pliers, wrenches, screwdrivers, hammers, axes, etc. 2.

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

Advantages and Disadvantages of Electric Arc Furnace and Induction Furnace Steelmaking

Electric Arc Furnace VS Induction Furnace Steelmaking Comparison of advantages and disadvantages of electric arc furnace and induction  furnace steelmaking 1. The induction furnace heats up quickly and has high thermal efficiency. The heat is generated inside the charge (steel liquid), so the heating is fast. In the arc furnace, the heat of the arc after the material is cleared must be transferred to the molten steel through the slag, which is indirect heating. Thermal efficiency is poor. The furnace is in the shape of a basin, and a large part of the heat of the arc is lost through the furnace cover and the furnace wall. 2. The oxidative burning loss of elements in induction furnace steelmaking is less. Because there is no ultra-high temperature action of the arc in the induction furnace steelmaking, the burning rate of the elements in the steel is low. 3. In the induction furnace steelmaking, the composition and temperature of the molten steel are relatively uniform.
