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.

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. High-frequency hardened crank pins, sprockets, camshafts, valves, various rocker arms, rocker shafts for various auto parts and motorcycle parts; various gears, spline shafts, transmission axles, High-frequ

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.
