Description
Technical field
The present invention relates to extraordinary metallurgical technology fields, and specifically, the present invention relates to a kind of vacuum arc furnace ignition auxiliary electrode furnaces
Outside weld connection device and its welding method.The vacuum arc furnace ignition auxiliary electrode furnace outside weld connection device and its welding method are used for vacuum
Welding between electric arc furnaces auxiliary electrode and consutrode is able to achieve the cylindric auxiliary electricity of different size (diameter, length)
Between pole and the cylindric consutrode of different size (diameter, length) by certain concentricity requirement outside vacuum arc furnace ignition
(being carried out using semi-automatic metal argon arc welding by welder's hand torch) welding, is welded with substituting original in vacuum arc furnace ignition
The mode connect.
Background technique
Vacuum (consutrode) electric arc furnaces, abbreviation electric arc furnaces are to heat the one of smelting metal using electric arc in a vacuum
Kind stove.Consutrode is made by being melt refining material, it is gradually used up in fusion process, is dripped after fusing and is condensed into crystallizer
Ingot.
According to the cylindric ingot shape of production different size (diameter, length), need using different size (diameter, length)
Cylindric consutrode.And the guide rod in smelting process as transmission consutrode is known as conductive material bar (or for electrode
Bar).There are two the effects of conductive material bar:
1) conductive, supply the high current of electric arc；
2) it clamps and consutrode is driven to move up and down.
In order to realize the conduction and clamping between conductive material bar, consutrode, both between conductive material bar, consutrode
Between be provided with different size (diameter, length) cylindric auxiliary electrode.One end of auxiliary electrode is clamped in by mechanism leads
On electrical materials and appliances bar, the other end is weldingly connected with consutrode.According to the present invention, the welding of auxiliary electrode refers to auxiliary electrode and consumable
Welding between electrode.
Currently, being welded in furnace for vacuum arc furnace ignition auxiliary electrode carries out, the course of work is as follows:
Furnace external application manual type by consutrode on crystallizer pedestal to middle placement, later, put on crystallizer shell
It is allowed to connect with pedestal, then the crystallizer equipped with consutrode is hung in into arc melting station, driving burner is rotated to smelter
At position, by the auxiliary electrode being clamped on conductive material bar and the consutrode levelling, the centering that are placed in melting station, make the two
Between axis it is consistent.
In above process, the levelling, centering of auxiliary electrode are carried out by electric arc furnaces X-Y-direction drive adjusting device, from
Levelling, the centering of power pole are carried out by manual type.Levelling, after centering with wooden wedge along crystallizer port perimeter by consutrode
It is fixed.Later, stove evacuation is closed to specified vacuum degree, and energization plays arc welding between auxiliary electrode and consutrode.Welding knot
Shu Hou, vacuum breaker, blow-on welding quality is checked and is handled abnormal conditions, if welding quality meets the requirements, takes out wood
Again stove evacuation is closed after chock to specified vacuum degree, is powered and is smelted.
However, there are following shortcomings for the welding in above-mentioned auxiliary electrode furnace:
1) accuracy of alignment is poor, and there are product quality hidden danger.
Firstly, consutrode outside furnace on crystallizer pedestal to middle placement, as centering benchmark crystallizer pedestal because
Usually all there is more serious deformation in pyrolytic semlting, and collision and throwing when due to smelting when the etch, crystallizer dismounting of molten steel
Light polishing, keeps the boundary line on crystallizer pedestal as measuring basis smudgy, seriously affects accuracy of alignment as a result,.
2) secondly, consutrode in the crystallizer of melting station in, equally, the crystallizer as centering benchmark is because of high temperature
It smelts and usually all there is deformation, and the crystallizer port shape as measuring basis is usually circular arc chamfering, boundary line is fuzzy not
Clearly, accuracy of alignment is also seriously affected.
In conclusion the accuracy of alignment due to consutrode is difficult to control, will cause between auxiliary electrode and consutrode
Concentricity be difficult to ensure, influence the stability of smelting process, bring hidden danger to product quality；Guarantee certain welding quality compared with
It is difficult.
Because operator cannot obviously observe and weld since being welded in closed furnace for auxiliary electrode carries out
Inevitably there is abnormal conditions (it is too long liquid metal trickling such as occur) in journey, must in order to determine whether welding quality meets the requirements
Must vacuum breaker, blow-on welding quality checked and handled abnormal conditions, thus, it is ensured that certain welding quality difficulty compared with
It is high.
3) energy consumption is high.After auxiliary electrode welds in furnace, in order to take out consutrode positioning wooden wedge, check welding quality
And handle abnormal conditions, it is necessary to which vacuum breaker blow-on carries out, and closes stove evacuation after being disposed again to specified vacuum degree, Fang Nengtong
Electric smelting, this process energy consumption are high.
