The development of vacuum induction melting furnace benefits from the application of SCR converter. The frequency converter USES electronic equipment to convert the three-phase alternating current frequency to the desired frequency through a dc central loop. Its power is 95-98%. The new generation of frequency converter USES CNC electronic circuit to provide various control scheduling and maintenance functions for the frequency converter. The rated power of frequency converter used in intermediate frequency induction melting furnace is constantly improved. The frequency converter of 9000kW is connected to the furnace of 12T, and the melting rate of molten iron is 18t/h. By increasing the power density of intermediate frequency induction melting furnace to 1000kW/ t, the melting period can be shortened to 35min.

The melting rate of induction melting furnace varies according to the furnace capacity. The melting rate of molten iron in intermediate frequency induction melting furnace is 0.14-35t/h. For example, the melting rate of 2-2.38t/h can be obtained by using a 2T capacity furnace, while the melting rate of 18-21t/ h can be obtained by using a 12T capacity furnace. The melting rate of the cold material is 0.75t/ h for 115T furnace, 1.5t/ h for 3T furnace, 2.5t/ h for 5T furnace and 4t/h for 10T furnace. Visible medium frequency induction furnace melting rate is greater than the power frequency induction melting furnace, it is a when choosing produce cast iron smelting equipment to small generation, using a smaller amount of medium frequency induction melting furnace instead of large capacity power frequency induction melting furnace, reduces the area already, have fallen a capital contribution, also ensure the continued supply of iron liquid, about homework, produce talents was beneficial to produce larger cast iron manufacturers. If the medium frequency induction melting furnace is used for molten iron smelting produced by continuous casting and centrifugal casting ductile iron pipe, it can replace the cupola, or double with blast furnace and cupola, its production ability will be brought into full play.

With the continuous increase of power density of intermediate frequency induction melting furnace, the safety of furnace, lining life and noise requirements are more and more high, the rationality of furnace body structure is more and more people pay attention to, during which heavy steel shell furnace has strong durability, high power and production rate, low noise, easy maintenance and repair and many other benefits.
