The induction melting furnace is suitable for melting various types of molten iron, satisfying the molten iron of various compositions and temperatures, and meeting the performance requirements of various molten irons. Has good adaptability. Because the induction melting furnace is relatively easy to adjust the composition, the process requires a narrower range of molten iron composition to make the casting performance more stable. The specific scope can be divided into multiple "brands" according to the type of casting. Or customize special composition requirements for individual castings. Because the power of the induction melting furnace is very large, the heating capacity is also strong, and different temperature ranges can be given to different castings to meet the requirements of the castings.

Induction melting furnace is an industrial heat treatment equipment with intermediate frequency power source as the main power source. So what are the technical characteristics of using intermediate frequency electric furnace equipment?

    1. The control circuit adopts the fourth-generation control board. The main core components are imported integrated circuits. All digital and non-relay control circuits ensure stable and reliable operation of the entire system.

    2. Easy operation and low maintenance cost.

    3. The rectified power factor is greater than or equal to 0.90.

    4. DC voltage is 500V, intermediate frequency voltage is 750V, and maximum rated output power is 750KW.

    5. High startup success rate.

    6, with over-current, over-voltage, under-voltage, phase loss, water pressure and other comprehensive protection to ensure the normal operation of the equipment.

    7, three-phase four-wire system.

    8. Multi-station structure can easily and quickly replace the furnace body according to different heated workpieces.

Compared with industrial frequency induction electric furnaces, induction frequency melting furnaces have high hump due to the large stirring force of the molten metal. This causes the slag in the middle part of the top surface of the molten pool to be pushed up to the crucible wall. Live the entire metal liquid surface, and it is easy to aggravate metal oxidation. Compared with it, the main advantages of an induction melting furnace equipped with a solid-state circuit static frequency converter are:

(1) The stirring force of the molten metal can be flexibly adjusted. From the point of view of metallurgy, different types of steels require different degrees of molten metal melting. For example, alloy cast iron hopes for moderate melt stirring, while ductile iron and malleable cast iron want larger molten stirring.

(2) The power density is large, and no three-phase balancing device is required. Due to the high concentration of energy and the moderate stirring movement of the molten metal in the molten pool, it is not only conducive to deoxidation, degassing, removal of inclusions, and uniformity of temperature and composition, but also due to the overheating of the molten metal, the added alloy melts rapidly, and the element burns less.

(3) It is convenient to melt and smelt the residual liquid, so batch operation method can be performed. This allows the alloy composition of the melt to be easily adjusted without limitation.

(4) It is not necessary to dry the wet or oily metal charge in advance.

(5) The thermal shutdown period does not consume electricity. From a metallurgical point of view, it allows the molten metal to exist only "once overheated", thereby shortening the melting time.
