Medium Frequency Furnace Leakage Furnace, Cause and Prevention  When a safety accident occurs, it should be reported to the leader or accident emergency team immediately. The medium frequency furnace body is leaking in a common accident. If no accident occurs, the coil copper tube will be broken, and the molten iron will contact with the coolant to cause an explosion. Therefore, the cause of the accident may be caused. Precautionary measures and plans for emergency measures should be given after the accident. Causes of Leakage and Furnace Accidents 1. The cooling time of the molten iron is too long and the cover is closed, and it is thermally expanded again. The extrusion lining causes cracks in the lining. During the melting process, the molten iron passes through the crack, causing the furnace to pass through, or ejecting from the knot, causing the furnace accident. 2. As the medium frequency furnace age increases, the volume of the lining becomes larger, ...

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 unifor...

The Core Principle of the Intermediate Frequency Melting Furnace The working principle of the intermediate frequency melting furnace is that the three-phase AC power supply provided by the State Grid forms a voltage-adjustable pulsating DC current through a three-phase full-controlled rectifier bridge (the device uses a thyristor). The DC current is filtered by the reactor LD and sent to a single-phase inverter bridge (the device uses a thyristor). The output of the inverter bridge is several tens to hundreds of times higher than the power supply frequency. The load adopts LC series-parallel oscillating circuit composed of the induction coil (including heating furnace charge) and intermediate frequency power capacitor, which has strong adaptability to load and reliable operation. By adjusting the control angle of the rectification trigger pulse, the rated power can be changed to achieve the purpose of power adjustment; the output frequency is the resonant frequency of the LC pa...

Medium Frequency Induction Melting Furnace Advantages The medium frequency induction melting furnace has the advantages of small size, lightweight, high efficiency, and favorable environment, which makes it a rapid replacement for coal-fired furnaces, gas furnaces, oil-fired furnaces, and ordinary resistance furnaces. It is a new generation of metal heating equipment. The medium frequency induction melting furnace has advantages over the power frequency induction melting furnace because of its high electrical efficiency and thermal efficiency, short melting time, less power consumption, less land occupation, lower investment, flexible production and easy implementation of process automation. The medium frequency induction melting furnace has the advantages that other cast iron melting furnaces do not have, and has been attracting remarkable development in recent years and is widely used in cast iron production. When the molten iron in the furnace reaches the pre-programmed t...
