Embodiment 1

[0009] Embodiment 1: with reference to attached figure 1 . An electric arc induction furnace, the lower half of a furnace body 1 is an induction furnace 3, and the upper half is an electric arc furnace 2. The electric arc furnace 2 is connected to a single-phase DC power supply or a three-phase AC power supply. The combination of electric arc furnace 2 and induction furnace 3 is as attached figure 1 As shown, its manufacturing process is the prior art, and will not be described here.

Embodiment 2

[0010] Embodiment 2: On the basis of Embodiment 1, a control method for an electric arc induction furnace, when the electric arc furnace 2 and the induction furnace 3 are working, the current controller instructs the electric arc furnace 2 and the induction furnace 3 to start, and the electric arc furnace 2 and the induction furnace 3 Heating and melting the metal material in the furnace, the temperature sensor transmits the temperature signal of the molten metal in the upper and lower parts of the furnace to the current temperature controller, and the current temperature controller compares the temperature of the molten metal in the upper and lower parts of the furnace. When the temperature difference between the upper and lower parts of the interior is greater than the set temperature error value, the current temperature controller instructs to increase the current input of the induction furnace 3, the power of the electromagnetic induction furnace is increased, and the fluidi...

Abstract

The invention relates to an electric arc induction furnace with not only the function of an electric induction furnace but also the function of an electric arc furnace, and a smelting control method. The bottom half part of the furnace body is the induction furnace, and the top half part is the electric arc furnace, and the input current of the electric arc furnace and the induction furnace is controlled by a current temperature controller. The electric arc induction furnace has the advantages that the induction furnace and the electric arc furnace are organically combined, so that the electric arc induction furnace has the function of the electric induction furnace and the function of the electric arc furnace; the electric arc induction furnace performs the characteristics of the induction furnace and the electric arc furnace and overcomes the defects of the induction furnace and the electric arc furnace so as to perfectly combine the induction furnace with the electric arc furnace; and the quality parameter of smelted special steel can be fully guaranteed under the control of the current temperature controller.

Description

technical field [0001] The invention relates to an electric arc induction furnace and a smelting control method which not only have the functions of an induction electric furnace but also have the functions of an electric arc furnace, and belong to the field of electric heating composite furnace manufacturing. Background technique [0002] Existing equipment used in the metallurgical industry adopts a single electric arc furnace or an induction furnace, both of which have their own advantages and disadvantages, and are mainly used for the production of metal quenched and tempered special alloy steel. Its shortcomings are: although the electric arc furnace has good heating performance, it does not have agitation, and cannot make the molten metal flow well, and its fluidity is poor. Although the induction furnace has good agitation, it cannot quickly transfer The metal on top of it is heated and melted at a slow rate. Contents of the invention [0003] Design purpose: To av...
