The medium frequency induction furnace mainly comprises a power supply, an induction coil and a crucible built by refractory materials in the induction coil. The crucible is filled with metal furnace charge, when the induction coil is connected with an alternating current power supply, an alternating magnetic field is generated in the induction coil, magnetic lines of force cut the metal furnace charge in the crucible, induced current is generated in the furnace charge, and the furnace charge is heated to be melted.
The charging link in the smelting process of the medium-frequency induction furnace is an important safe production process, and improper charging easily causes the bridging phenomenon of furnace burden, so that the risk of furnace penetration can be caused when the ultra-high temperature smelting of metal liquid under the bridge in the furnace corrodes the furnace lining seriously. The intermediate frequency furnace is mainly added with recycled raw materials such as scrap steel and the like for smelting, the raw materials have different shapes, and the raw materials are generally required to be treated to meet the smelting process. However, the mechanically-added residual flocculent waste is large in volume and fluffy and cannot be directly fed into a furnace, and due to the fact that the mechanically-added residual flocculent waste contains a large amount of alloy elements, the added value is high, the mechanically-added flocculent waste can be utilized only by a mechanical briquetting treatment mode, and the briquetting volume cannot be too large to be fed into the furnace. This treatment method is long in cycle and high in processing cost.
