Abstract
The vacuum consumable electric arc skull crucible of supply power coaxially, comprises red copper crucible assembly and coaxial conductive bar assembly; Red copper crucible end flanges is symmetrically installed with two cover conduction ear, support ear and spring mechanisms; Two groups of coaxial conductive bar assembly actions under the driving of two groups of stove outside cylinders; Electric conduction rod component is made up of support bar, conducting rod, water-cooled steel bushing and conducting rod control cylinder; The conduction flange of two groups of conducting rods and crucible flange face compress and produce certain extrusion stress.The power supply mode of domestic skull crucible crucible before the present invention changes, adopt symmetrical powering, make melting electric arc surrounding magnetic field even, eliminate the red copper crucible caused because of magnetic bias to be leaked by arc through, produce the problem of steam and hydrogen detonation, simultaneously crucible entirety can output furnace chamber, installs, cleaning, maintenance be all very convenient.
Description
Technical field
The invention belongs to the improvement of the vacuum consumable electric arc skull crucible in the casting technology field of the rare metal such as titanium, zirconium.
Background technology
Vacuum consumable electric arc skull crucible outside Present Domestic has plenty of in power supply mode is powered by crucible water jacket both sides tipping pitman; Have plenty of and powered by crucible water jacket tipping pitman side.Tipping pitman should give crucible water flowing, power again, also want carry-over moment, and will repeatedly dismantle, these structures above-mentioned and power supply mode all also exist stove internal magnetic field skewness phenomenon, cause Distribution of Magnetic Field in fusion process uneven, the impact that electric arc is subject to magnetic field force produces arc blow, and cold-crucible is easily by arc through, and then there is steam and hydrogen detonation, very dangerous, and affect manufacturing schedule, for enterprise causes very large economic loss.
Summary of the invention
The object of this invention is to provide a kind of vacuum consumable electric arc skull crucible of supply power coaxially.
The vacuum consumable electric arc skull crucible of supply power coaxially, there is crucible, it is symmetrically installed with crucible conduction ear, support ear at crucible both sides end flanges, support ear is connected with crucible end flanges, conduction ear is positioned at support ear top and by connecting rod through being connected as a single entity, between connecting rod bottom and support ear, spring mechanism is housed, one group two coaxial conductive bar assemblies are positioned at connecting rod top and move up and down under the driving of two groups of stove outside cylinders and realize connecting with connecting rod or being separated.
Electric conduction rod component comprises support bar, spherical shell, steel ball, fairlead, crane, lift cylinder, conductive anode rod, water-cooled steel bushing, conduction flange, water-cooled cable, compression cylinder formation; Support bar is positioned at the support of center as whole assembly, and conductive anode rod is enclosed within outside support bar, and compression cylinder is housed on support bar top and compression cylinder is connected with conducting rod upper end, and water cooled steel is sleeved on conductive anode rod outside; Connecting rod upper end is connected with conductive anode rod lower end by spherical shell, steel ball, fairlead, pneumatic dop.
The present invention adopts rational crucible power supply mode, i.e. supply power coaxially, makes the outer stove internal magnetic field of stove be evenly distributed, thus reaches and to eliminate in vacuum consumable electric arc skull crucible fusion process electric arc by the impact of surrounding magnetic field, easily puncture the drawbacks such as crucible, and in production process operate, easy to maintenance.

Detailed description of the invention
As Figure 1-3, specifically, supply power coaxially skull crucible structure of the present invention comprises crucible assembly and coaxial conductive bar assembly.Crucible assembly is primarily of red copper crucible, cooling jacket and water proof cover composition; Two groups of crucible conductions ear, support ear and spring mechanisms are symmetrically installed with at the end flanges of red copper crucible.Coaxial conductive bar assembly comprises two groups of symmetrical electric conduction rod component of installing, this two groups of electric conduction rod component action under the effect of two stove outside cylinders; Electric conduction rod component 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; Electric conduction rod component is made up of support bar, conducting rod, water-cooled steel bushing and conducting rod control cylinder; Electric conduction rod component structure 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 limits by guide post.
Crucible arrives assigned address, under the driving of lift cylinder, two groups of electric conduction rod component move downward, after arriving stroke, compression cylinder drives conducting rod to move downward, fairlead is to steel ball effect, connecting rod blocks by steel ball, and simultaneously to crucible generation lifting force upwards, conduction flange and crucible flange face are combined closely and conducted electricity; Conducting rod overcoat one stainless steel water collar, the outer one end of conducting rod stove is connected with water-cooled cable.When 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 by spring action, steel ball is pushed back initial position, and coaxial conductive bar assembly is lifting cylinder fast lifting, crucible is overturn in time, pours into a mould.
Vacuum consumable electric arc skull crucible fusing operating mode process is: under vacuum conditions, the titanium consutrode be melted is connect negative pole, crucible connects positive pole, through a DC source, make two interpolars produce arc discharge, cation gets to negative electrode (consutrode), and electronics gets to (crucible) on anode, heat energy is become to make material melting converting electric energy, as shown in Figure 1.During fusing, liquid titanium is with the form of molten drop, by the high-temperature electric arc district of about 4700 DEG C, dropping onto in crucible molten bath, in the process of dripping and when keeping liquid in water jacketed copper crucible, there is a series of physical-chemical reaction in molten drop, under the effect of high arc temperature heating, the continuous fusing of consutrode consumes, and constantly rising in molten bath, then motlten metal liquid is poured in mould into the process being condensed into foundry goods.
