Description
Technical field
The present invention relates to consumable electrode vacuum furnace melting field, especially a kind of consumable electrode vacuum furnace electrode shove charge servicing unit and molten
Smelting method.
Background technology
Consumable electrode vacuum furnace is a kind of vacuum smelting equipment of melting refractory metal, between consutrode and crystallizer crucible
Thermal source is used as by high temperature caused by arc discharge, will be metal material melting, and carry out in cold-crucible solidifying the mistake of ingot
Journey.Its process characteristic is that melting is carried out in water cooling Cu crystallizer, and fusion process is the electric arc work in DC low-voltage, high current
Carried out under, it is general to obtain final finished ingot using melting twice or three times melting.When shove charge before melting works, welding
In the practical operation of auxiliary electrode and electrode bar, electrode bar due to bottom can not ensure definitely it is smooth, it is relatively heavy in crucible
Force direction, which always has certain angle, causes electrode incline, thus electrode is placed in copper crucible carry out center centering be one very
Important work.Current centering means are bolt, the benefit of chock block in the gap middle pad of crucible and electrode bar
It is simple to operate, processing is convenient, but inferior position is it is also obvious that wooden unit belongs to combustibles, in welding auxiliary electrode and electrode
During be easy to high temperature cabonization, aoxidize, pollution to a certain extent caused to composition atmosphere in stove, while after wooden unit is carbonized
It may fall into crucible, cause internal contamination, increase the melting pollutant of melting titanium zirconium and metallic nickel ingot.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of substitution wood cushion block and polluted so as to reduce in stove, and subtract
The time aligned less, the consumable electrode vacuum furnace electrode shove charge servicing unit of product quality is improved while improving production efficiency and is melted
Smelting method.
The technical solution adopted for the present invention to solve the technical problems is：Consumable electrode vacuum furnace electrode shove charge servicing unit, bag
Include electrode fixing end and the device being fixedly connected with electrode fixing end dress takes end, electrode fixing end periphery is provided with flame retarding construction.
It is further that the flame retarding construction is flame retardant rubber.
It is further that the electrode fixing end is arc-shaped slot structure.
It is further that the arc-shaped slot structure arc range is 90 °~180 °.
It is further that it is titanium or high-strength steel that the electrode fixing end and device dress, which take the material at end,.
It is further consumable electrode vacuum furnace electrode shove charge method of smelting, it is characterised in that comprise the following steps：
A, the electrode bar that compacting is welded is ready to, the then shove charge in crucible by electrode bar；
B, after centering operation being completed in electrode bar bottom, the shove charge servicing unit, is then vacuumized in sealing on card
Afterwards, the welding of auxiliary electrode and electrode bar is carried out, welding terminates vacuum breaker after cooling and checks weld seam；
C, after weld seam ensures firm stable, the shove charge servicing unit is taken out and carries out melting.
The beneficial effects of the invention are as follows：In actual use, due to the presence of the present apparatus, with regard to eliminating traditional wedge naturally
Shape wooden unit.Electrode bar is fixed by electrode fixing end, under allowing whole welding to be in stable, being accurately controlled, from
And the quality of melting is effectively guaranteed, and ensure that final product quality.Present invention is particularly suitable for consumable electrode vacuum furnace to melt
Among sweetening process.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the schematic diagram of arc-shaped slot structure radian of the present invention.
In figure mark for：Device dress takes end 1, electrode fixing end 2, arc-shaped slot structure radian measure alpha.
Embodiment
The present invention is further described below in conjunction with the accompanying drawings.
Consumable electrode vacuum furnace electrode shove charge servicing unit as shown in Figure 1 and Figure 2, including electrode fixing end 2 and fixed with electrode
The device dress that end 2 is fixedly connected takes end 1, and the periphery of electrode fixing end 2 is provided with flame retarding construction.
The actual use method of the present invention is such：A, the electrode bar that compacting is welded is ready to, then by electrode
Rod shove charge in crucible；B, after centering operation being completed in electrode bar bottom, the shove charge servicing unit, is then being sealed on card
After vacuumizing, the welding of auxiliary electrode and electrode bar is carried out, welding terminates vacuum breaker after cooling and checks weld seam；C, weld seam ensures
After firm stable, the shove charge servicing unit is taken out and carries out melting.The present apparatus both can be used for the one of pure titanium TA1 electrode bar
Secondary pure titanium ingot TA1 melting, can be used for the melting of the secondary ingot of titanium alloy TC 4 electrode bar.The electrode fixing end 2 and dress
It is preferably titanium or high-strength steel to put dress and take the material at end 1.
In order to prevent scraping between the present apparatus and crucible and electrode bar etc. from injuring, the resistance of the periphery of electrode fixing end 2 setting
It is preferably flame retardant rubber to fire structure.By the electric shock baton fixed is mostly cylinder, so, the electrode fixing end 2 is preferably
Arc-shaped slot structure.As shown in Fig. 2 wherein, in order to it is stable accommodate and dismantle it is convenient between obtain optimal balance, preferred institute
Arc-shaped slot structure radian (α) scope is stated as 90 °~180 °.
The titanium ingot prepared using present apparatus melting, its titanium ingot composition present stable, composition more uniformly, impurity element more
Few, the metallochrome of more homogeneous and bright is presented in ingot casting, and the competitiveness of product in market is also improved while quality is improved.This dress
Put dress and take the accuracy for conveniently, also improving electrode bar shove charge.
