Abstract
The utility model relates to an electric arc induction furnace which not only has the functions of an electric induction furnace, but also has the functions of an arc furnace. The lower half part of the furnace body is an induction furnace, the upper half part of the furnace body is an arc furnace, and the input current of the arc furnace and the induction furnace are controlled by a current temperature controller. The electric arc induction furnace has the following advantages of organically combining the induction furnace with the arc furnace, not only having the functions of the induction furnace, but also having the functions of the arc furnace, not only bringing respective advantages of the two electric furnaces into play, but also overcoming the defects of the two electric furnaces, realizing perfect combination of the induction furnace and the arc furnace, and fully ensuring the quality parameters of special smelted steel by the control of the current temperature controller.
Description
Technical field
The utility model relates to a kind of electric induction furnace function that both had, and a kind of electric arc induction furnace that has the electric arc furnaces function again belongs to the compound stove of electrical heating and makes the field.
Background technology
Existing metallurgy industry equipment adopts single electric arc furnaces or induction furnace, and two kinds of electric furnaces respectively have pluses and minuses, are mainly used in the production of the modified special steel alloy of metal.Its weak point is: though electric arc furnaces has good heating property, but it does not have stirring, can't make good the flowing of molten metal, and it is mobile poor, though and induction furnace has good stirring, it can't be slow with the METAL HEATING PROCESS fusion and the firing rate that are positioned at its top apace.
The utility model content
Purpose of design: avoid the weak point in the background technology, design a kind of electric induction furnace function that both had, a kind of electric arc induction furnace that has the electric arc furnaces function again.
Design: in order to realize above-mentioned purpose of design.1, body of heater the latter half is that induction furnace, the first half are the design of electric arc furnaces, is one of technical characterictic of the present utility model.The purpose of doing like this is: because electric arc furnaces has good heating property, it can be apace with the METAL HEATING PROCESS fusion of upper of furnace body, though and induction furnace has good stirring, it can make the metal liquid behind the heating and melting flow apace, thereby has guaranteed the relative uniformity of body of heater inner metal liquid temperature.Its technical scheme: a kind of electric arc induction furnace, body of heater the latter half are that induction furnace, the first half are electric arc furnaces.2, electric arc furnaces and induction furnace input current size is two of a technical characterictic of the present utility model by the design of current temperature controller control.The purpose of doing like this is: because the main application of electric arc induction furnace is to be used for special steel to smelt, and whether the good temperature with bad and its smelting of special steel smelting back metallographic structure evenly has direct relation, therefore for the arc induction furnace, whether up to standard the uniformity that same burner hearth, different heating source institute melt metal liquid can be kept temperature be to be related to special steel Q factor key.The application adopts the current temperature controller to regulate and control the heating-up temperature of electric arc furnaces, the agitated conditions of regulation and control induction furnace, make the molten metal in the burner hearth can satisfy the required temperature of special steel smelting, can make the temperature of top and the bottom molten metal in the burner hearth reach the value that sets again, thereby realize the automatic control of electric arc induction furnace smelting temperature.
Technical scheme: a kind of electric arc induction furnace, body of heater the latter half are that induction furnace, the first half are that electric arc furnaces and electric arc furnaces and induction furnace input current size are by the control of current temperature controller.
The utility model is compared with background technology, and the one, induction furnace and two kinds of electric furnaces of electric arc furnaces are combined, both had the function of induction furnace, have the function of electric arc furnaces again; The 2nd, not only bring into play speciality separately, and overcome shortcoming separately again, realized the perfect adaptation of induction furnace and electric arc furnaces; The 3rd, by the control of current temperature controller, make the Q factor of the special steel of being smelted arrive sufficient assurance.
Description of drawings
Fig. 1 is a kind of structural representation of electric arc induction furnace.
The specific embodiment
Embodiment 1: with reference to accompanying drawing 1.A kind of electric arc induction furnace, body of heater 1 the latter half are that induction furnace 3, the first half are electric arc furnaces 2.Described electric arc furnaces 2 order phase dc source or three-phase alternating-current supplies.Electric arc furnaces 2 combines as shown in Figure 1 with induction furnace 3, and its manufacture craft is a prior art, is not described herein at this.
A kind of control method of electric arc induction furnace, when electric arc furnaces 2 and induction furnace 3 work, current controller instruction electric arc furnaces 2 and induction furnace 3 start, the metalliferous material that 3 pairs of electric arc furnaces 2 and induction furnaces are positioned at burner hearth carries out heating and melting, temperature sensor passes to the current temperature controller with top and the bottom molten metal liquid temperature signal in the furnace chamber, the current temperature controller compares the temperature of top and the bottom molten metal in the burner hearth, when the difference of top and the bottom temperature value in the burner hearth during greater than the temperature error values that sets, the instruction of current temperature controller increases the electric current input of induction furnace 3, electromagnetic induction furnace power increases, strengthen the flowability of burner hearth inner metal liquid, when the difference of molten metal temperature value in top and the bottom in the burner hearth and temperature value reached the scope that sets, current temperature controller instruction electric arc furnaces 2 and induction furnace 3 quit work.
What need understand is: though the foregoing description is to the mentality of designing of the present utility model detailed text description of contrasting; but these text descriptions; just the simple text of the utility model mentality of designing is described; rather than to the restriction of the utility model mentality of designing; any combination, increase or modification that does not exceed the utility model mentality of designing all falls in the protection domain of the present utility model.
Claims (2)
1. electric arc induction furnace is characterized in that: body of heater the latter half is that induction furnace, the first half are that electric arc furnaces and electric arc furnaces and induction furnace input current size are by the control of current temperature controller.
2. electric arc induction furnace according to claim 1 is characterized in that: described electric arc furnaces order phase dc source or three-phase alternating-current supply.
