Abstract
The utility model relates to a vacuum self-consuming arc kish furnace for coaxial power supply. The vacuum self-consuming arc kish furnace comprises a red copper crucible component and coaxial conducting rod components, wherein two sets of conducting lugs, supporting lugs and spring mechanisms are symmetrically mounted on the end face flanges of a red copper crucible; two sets of coaxial conducting rod components act under the driving of two sets of external cylinders; each conducting rod component consists of a supporting rod, a conducting rod, a water-cooling steel jacket and a conducting rod control cylinder; conducting flanges of two sets of conducting rods are compressed with the flange surface of the crucible to form certain extrusion stress. The previous power supply mode of a kish furnace crucible in our country is changed, and symmetrical power supply is adopted, so that the magnetic field around a smelting arc is uniform, the problems of water leakage since the red copper crucible is punctured by arc, steam generation and hydrogen detonation caused by bias magnet are solved, and the crucible can go out of a furnace chamber integrally; the vacuum self-consuming arc kish furnace is extremely convenient to mount, clean and maintain.

Detailed description of the invention
As Figure 1-3, specifically, the utility model supply power coaxially skull crucible structure comprises crucible assembly and coaxial conductive bar assembly.Crucible assembly is mainly made up of red copper crucible, cooling jacket and water proof cover; Be symmetrically installed with two groups of crucible conductions ear, support ear and spring mechanisms at the end face flange of red copper crucible.Coaxial conductive bar assembly comprises two groups of symmetrical conducting rod assemblies of installing, and these two groups of conducting rod assemblies move under the effect of two stove outside cylinders; Conducting rod assembly comprises support bar, spherical shell, steel ball, fairlead, crane, lift cylinder, guide post, conducting rod, water-cooled steel bushing, conduction flange, water-cooled cable, compression cylinder.Described coaxial conductive bar assembly by and spring mechanism form; Conducting rod assembly is made up of support bar, conducting rod, water-cooled steel bushing and conducting rod control cylinder; Conducting rod modular construction is inside and outside nesting type structure.Conducting rod is exterior is furnished with a stainless steel water jacket.The conduction flange of two groups of conducting rods and crucible flange face compress and produce certain extrusion stress.Lift cylinder is arranged on vacuum melting outdoor, is connected by crane with bracing frame, and the action of crane is limited by guide post.
Crucible arrives assigned address, under the driving of lift cylinder, two groups of conducting rod assemblies move downward, after arriving stroke, compression cylinder drives conducting rod to move downward, fairlead is to steel ball effect, steel ball blocks connecting rod, crucible is produced to lifting force upwards simultaneously, conduction flange and the crucible flange face conduction of combining closely; Conducting rod overcoat one stainless steel water-cooled cover, the outer one end of conducting rod stove is connected with water-cooled cable.In the time that the fusing of titanium liquid reaches fusing amount, cut off fusing power supply, compression cylinder piston moves up and drives conducting rod to promote simultaneously, connecting rod is subject to spring action, steel ball is pushed back to initial position, and coaxial conductive bar assembly, by lift cylinder fast lifting, makes crucible overturn in time, pour into a mould.
Vacuum consumable electric arc skull crucible fusing operating mode process is: under vacuum environment, the titanium consutrode being melted is connect to negative pole, crucible connects positive pole, through a DC source, make two interpolars produce arc discharge, cation is got to negative electrode (consutrode), and electronics is got to (crucible) on anode, electric energy is transformed into heat energy and makes material melting, as shown in Figure 1.When fusing, liquid titanium is with the form of molten drop, by the high-temperature electric arc district of approximately 4700 DEG C, drop onto in crucible molten bath, when molten drop keeps liquid in the process of drippage and in water jacketed copper crucible, a series of physical-chemical reaction occurs, under the effect of high arc temperature heating, the continuous fusing consumption of consutrode, constantly rising in molten bath, then pours motlten metal liquid into be condensed into foundry goods in mould process.
