The cooling methods of medium frequency induction furnace are mainly divided into water cooling and air cooling, among which water cooling is the most widely used cooling method. Water cooling can be divided into internal circulation cooling and external circulation cooling. Cooling methods include pool cooling, open cooling tower and closed cooling tower. Cooling Method of Medium Frequency Induction Furnace Water Cooling: Internal circulation cooling: Use pure water to form a closed cycle inside the induction coil, electrode and other components to take away heat.  External circulation cooling: Through spraying, heat exchange and other methods, the internal circulation cooling water is cooled to reduce the water temperature so that it can be continuously recycled.  Cooling water requirements: There are requirements for the water quality, pressure and temperature of cooling water. For example, the cooling water system of the induction coil and capacitor usually uses industrial pressu...

  The main material of the steelmaking electric arc furnace is scrap steel, which is a low-cost, easily available recycled material and an ideal choice for steel production. Electric arc furnaces for steelmaking can be divided into alkaline method and acid method according to the different lining materials and slag-making materials, of which the alkaline method is the most commonly used. Smelting Materials of Steelmaking Electric Arc Furnace The main materials of steelmaking electric furnaces include: scrap steel, pig iron, direct reduced iron, graphite electrodes, lining materials and metallurgical auxiliary materials. These materials play different roles in the process of industrial furnace steelmaking, and jointly ensure the smooth progress of the steelmaking process and the quality of steel. Main Materials & Functions of EAF Melting Furnace: 1. Scrap steel:   As the main raw material for electric arc furnace steelmaking, it accounts for more than 70% and is the core of...

  Advantages of DC Electric Arc Furnace DC Electric Arc Furnace  is an arc furnace that uses DC power to supply electricity. Like AC Arc Furnace, it also uses the arc generated between the electrode and the charge (or molten pool) to generate heat to achieve the purpose of smelting. The structural difference between DC Arc Furnace and AC Arc Furnace is: Three electrodes that can move up and down are installed on the top of the three-phase AC Arc Furnace, while the DC Furnace only has one electrode that can move up and down on the top of the furnace, and the other electrode is fixed at the bottom of the furnace. The DC Electric Arc Furnace needs DC power supply, so it has one more set of rectifier equipment to convert three-phase AC power into DC power than the three-phase AC Arc Furnace. Compared with the traditional AC arc furnace, the main advantages of the DC arc furnace are: (1) The arc is stable and concentrated, the molten pool is well stirred, the temperature ...

A ferrochrome furnaces (also called a submerged arc furnace or resistance furnace) is an industrial electric furnace used to smelt raw materials such as ore, carbonaceous reducing agent and solvent. It is mainly used to produce ferroalloys such as ferrosilicon, ferromanganese, ferrochrome, ferrotungsten, silicon-manganese alloy, and chemical raw materials such as calcium carbide. The submerged arc furnaces uses the energy of the arc and the resistance heating generated by the current through the charge to melt the metal through the submerged arc operation of the electrode, and gradually adds materials, intermittently discharges iron slag, and operates continuously.  Ferrochrome Furnaces - Submerged Arc Furnace Features Definition: A ferrochrome submerged arc furnace is an industrial electric furnace for smelting ore and ferroalloys. Uses: SAF is mainly used to produce ferroalloys such as ferrosilicon, ferromanganese, ferrochrome, etc., as well as chemical raw materials such as calci...

  1500KW DC Furnace is an electric arc furnace that uses direct current as energy. Like an AC EAF, it uses the arc generated between the electrode and the charge (or molten pool) to generate heat to achieve the purpose of smelting. It can be used to melt steel or alloys and non-ferrous metals. In addition, blast furnace slag is also processed using a DC electric arc furnace. Let us congratulate Sanrui Electric Furnace for having sold its 1500KW DC electric furnace and it is in orderly production. So what are its characteristics and product composition, and part of the supply list, let us understand together. Advantages of DC Electric Arc Furnace Compared with traditional AC electric arc furnaces, the main advantages of DC EAF are: (1) The arc is stable and concentrated, the molten pool is well stirred, the temperature distribution in the furnace is uniform, and the lining erosion is small; (2) The current and voltage fluctuations are small, the impact on the power grid is reduced, ...
