Abstract
The present invention relates to one and both there is electric induction furnace function, have again a kind of electric arc induction furnace and the smelting control method of electric arc furnaces function, body of heater the latter half is induction furnace, the first half is electric arc furnaces and electric arc furnaces and induction furnace input current size are controlled by current temperature controller.Advantage: one is induction furnace and electric arc furnaces two kinds of electric furnaces are combined, and has both had the function of induction furnace, has had again the function of electric arc furnaces; Two is not only played respective speciality, and overcomes again respective shortcoming, achieves the perfect adaptation of induction furnace and electric arc furnaces; Three is the control by current temperature controller, makes the Q factor of smelted special steel arrive sufficient guarantee.
Description
Technical field
The present invention relates to one and both there is electric induction furnace function, there is again a kind of electric arc induction furnace and the smelting control method of electric arc furnaces function, belong to electrical heating composite furnace and manufacture 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: although electric arc furnaces has good heating property, but it does not have stirring, the flowing that molten metal is good cannot be made, its poor fluidity, and although induction furnace has good stirring, it cannot will be located thereon the METAL HEATING PROCESS melting in portion rapidly and firing rate is slow.
Summary of the invention
Purpose of design: avoid the weak point in background technology, design one had both had electric induction furnace function, had again a kind of electric arc induction furnace and the smelting control method of electric arc furnaces function.
Design: in order to realize above-mentioned purpose of design.1, body of heater the latter half is induction furnace, the first half is the design of electric arc furnaces, is one of technical characteristic of the present invention.The object done like this is: because electric arc furnaces has good heating property, it can rapidly by the METAL HEATING PROCESS melting of upper of furnace body, and although induction furnace has good stirring, metal liquid after it can make heating and melting flows rapidly, thus ensure that 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 is induction furnace, the first half is electric arc furnaces.2, the design that controlled by current temperature controller of electric arc furnaces and induction furnace input current size is technical characteristic two of the present invention.The object done like this is: the main application due to electric arc induction furnace is smelted for special steel, and special steel is smelted the good of rear metallographic structure and badly whether is evenly had direct relation with the temperature of its smelting, therefore for arc induction furnace, the molten metal of same burner hearth, the melting of different heating source institute can be kept the uniformity of temperature, be related to special steel Q factor key whether up to standard.The application adopts 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 burner hearth can meet special steel smelt needed for temperature, the value that the temperature of top and the bottom molten metal in burner hearth reaches set can be made again, thus realize the automatic control of electric arc induction furnace smelting temperature.
Technical scheme 1: a kind of electric arc induction furnace, body of heater the latter half is induction furnace, the first half is electric arc furnaces and electric arc furnaces and induction furnace input current size are controlled by current temperature controller.
Technical scheme 2: a kind of control method of electric arc induction furnace, when electric arc furnaces and induction furnace work, current controller instruction electric arc furnaces and induction furnace start, electric arc furnaces and induction furnace carry out heating and melting to the metalliferous material being positioned at burner hearth, temperature sensor by the molten metal liquid temperature signal transmission of top and the bottom in furnace chamber to current temperature controller, current temperature controller compares the temperature of top and the bottom molten metal in burner hearth, when in burner hearth, the difference of top and the bottom temperature value is greater than set temperature error values, the instruction of current temperature controller increases the electric current input of induction furnace, electromagnetic induction furnace power increases, strengthen the mobility of burner hearth inner metal liquid, when the difference of molten metal temperature value in top and the bottom in burner hearth and temperature value reach set scope, current temperature controller instruction electric arc furnaces and induction furnace quit work.
The present invention is compared with background technology, and one is induction furnace and electric arc furnaces two kinds of electric furnaces are combined, and has both had the function of induction furnace, has had again the function of electric arc furnaces; Two is not only played respective speciality, and overcomes again respective shortcoming, achieves the perfect adaptation of induction furnace and electric arc furnaces; Three is the control by current temperature controller, makes the Q factor of smelted special steel arrive sufficient guarantee.
