In addition, because the inductor copper pipe is pipe, the inductor copper pipe number of turn of work section that is positioned at the casting furnace middle part is more; Impedance is big, work area is less; Therefore intermediate frequency power supply is difficult to increase to the power output of inductor copper pipe, and work area causes the reactive power proportion bigger for a short time, causes the diameter of treating the founding bar to be difficult to increase; Founding speed is difficult to improve, and production efficiency is relatively low.
Summary of the invention
The technical problem that the utility model will solve provides that a kind of resistance to elevated temperatures is good, long service life, but founding magnetic conduction and non-magnet material, the multi-functional founding stove of electric induction applied widely.
The utility model is achieved in that it has a body of heater; Described body of heater be by the inspection microscope base of arranging up and down and base, is connected the insulation stove tube of inspection microscope base and base and in the shape of a spiral the inductor copper pipe that is preset in the stove tube that insulate of shape constitute; The two ends of described inductor copper pipe are drawn by the upper and lower part of insulation stove tube respectively; The inductor copper pipe is positioned at a section of workspace, body of heater middle part and draws two terminals by insulation stove tube; Below body of heater, be provided with pallet through a reciprocal elevating mechanism; Its special character is: the inwall at insulation stove tube is installed with corundum furnace liner, and the two ends of corundum furnace liner are affixed with inspection microscope base and base respectively, is preset with by the metal tantalum furnace lining of tantalum at the corresponding body of heater of corundum furnace liner inner chamber middle part.
The multi-functional founding stove of above-mentioned electric induction; The described cross section that is positioned at the inductor copper pipe of workspace, body of heater middle part is ellipse, to reduce the inductor copper pipe number of turn of work section, reduces impedance; Increase work area; Reduce reactive power, thereby can increase the power output and the diameter of treating the founding bar of intermediate frequency power supply, improve founding speed and production efficiency.
The multi-functional founding stove of above-mentioned electric induction is respectively equipped with the rectangular coil groove in inspection microscope base bottom and base top, and the upper and lower part of described inductor copper pipe is wrapped in respectively on the helicla flute of inspecting microscope base bottom and base top, to improve the intensity of casting furnace.
The utility model has the advantages that: owing to be installed with corundum furnace liner at the inwall of insulation stove tube; The two ends of corundum furnace liner are affixed with inspection microscope base and base respectively; And the fusing point of corundum material up to 2000 ℃ and hardness very high; Therefore can effectively protect insulation stove tube, the direct collision that receives bar when avoiding charging during with work exposed at high temperature, improve the resistance to elevated temperatures and the service life of insulation stove tube and whole body of heater; Owing to be preset with by the metal tantalum furnace lining of tantalum at the corresponding body of heater of corundum furnace liner inner chamber middle part; And the fusing point of tantalum metal is up to 3000 ℃; But therefore pass through, and permeability magnetic material directly utilizes the principle founding of kelvin effect by tantalum furnace lining founding non-magnet material and little permeability magnetic material of the heating of inductor copper pipe, applied widely; But the various fusing points of founding are lower than the non-ferrous metal and the nonmetallic materials of tantalum metal, also can be used to accomplish the sintering process and the Technology for Heating Processing of metal material.
