Characteristics of induction melting furnace

Time:2021-02-10   Nums:3050

 At present, the medium frequency electric furnace has been developed rapidly, and it has the potential to replace the cupola as long as the power supply is sufficient. Induction melting furnace can be divided into induction melting furnace, power frequency induction furnace and intermediate frequency induction furnace. At present, the capacity of coreless power frequency induction furnace has reached 110 T, while that of cored power frequency induction furnace has reached 270 T. in recent years, the development of intermediate frequency induction furnace and its advantages have injected new vitality into the production of cast iron.

The frequency induction furnace can make the metal melt and raise the temperature, and the heating is uniform, the burning loss is small, it is convenient to adjust the composition of molten iron, and the pollution is small. However, the frequency induction furnace is usually used for remelting and heating of metals and alloys because of its slow melting speed, unfavorable slagging, need of starting block and inflexible production. In addition, the power factor of power frequency induction furnace is low, and a large number of compensation capacitors are needed, which also increases the floor area and equipment investment.

The medium frequency induction furnace has the advantages of high electrical and thermal efficiency, short melting time, low power consumption, less floor space, low investment, easy to realize process automation and production flexibility. Medium frequency induction furnace is suitable for melting cast iron, especially alloy cast iron, nodular cast iron and vermicular cast iron. It also has strong adaptability to burden, and the variety and lump size of burden can be changed in a wide range. It should be pointed out that although the medium frequency induction furnace has many advantages and develops rapidly, the power frequency induction furnace is still a good equipment in the aspects of liquid iron storage, heat preservation, alloy composition adjustment and overheating, especially the duplex furnace used as blast furnace, cupola and other smelting furnaces.
