Description
Technical field
The present invention relates to electric furnace steelmaking technology field, specifically a kind of electrode fishing device and its Refloatation method.
Background technique
In electric furnace smelting production line, electrode belongs to one of extremely important metallurgical equipment.In electric furnace station, electrode passes through
Iron and steel stock is fused into molten steel by electric arc, while electrode is collapsed by electric arc, shake furnace body, solid iron and steel stock again, slag making materials are exhausted
Phenomena such as edge and the external force generated, the quality of electrode material has the factors such as deviation in addition, be easy to cause electrode fracture, especially
It is to finish the process of melting down in electric furnace steel tapping process or tapping, if it is too fast to shake furnace body, it is easy to by electrode fracture.If in steel
When expecting melting stage electrode fracture, electrode, which is understood uprightly or is tilted a certain angle, to be stood above bell, usually manually by metal
Steel chain does that one end that electrode exposes bell is locked at lock tube, then is hung out chain and electrode together with driving.Such side
The drawbacks of method is that bell overhead gas is hot, and bell tool, there are three electrode hole, personnel's operating process sight is impacted, breathing is tired
It is difficult, be easy to fall into electrode hole and cause to burn.If the stage electrode fracture after the electric furnace thawing phase, the electrode to fracture can be swum in
, manually can not be by metal latch chain case on the electrode above molten steel, electrode can give smelting molten steel carburetting in the case where can not pulling out
Production brings detrimental effect.
In refining station, electrode will push up slag heating by electric arc in ladle, top slag transfers heat to molten steel again.It is refining
Process it sometimes appear that: just into refining the molten steel top of the slag crust, refining furnace cover dropping process be obstructed inclination, carburetting when ladle in blow
Phenomena such as argon flow is bigger than normal, electrode contact quality existing defects, worker operate lack of standardization, equipment there are abnormal accidents, these
It is likely to lead to electrode fracture, the shorter electrode meeting lateral drift to fracture is on the ladle top of the slag, and longer meeting oblique is in steel
In containment wall or steel ladle edge, for longer break electric pole, need manually to do metal steel chain at lock tube, by electrode one end
It is locked, then is hung out chain and electrode together with driving.Because refining electrode does not have the water-spraying control equipment of electric furnace electrode, so electric
Extremely rubescent length is longer than electric furnace electrode, the electrode fallen down that often fractures all be it is rubescent hot, personnel set metal steel
It is difficult when chain, be not easy to entangle firm, it is longer to influence the production time, so influence postorder VD vacuum processing time and
Pulling speed of continuous casting etc..For noncontinuous electrode of the lateral drift on the ladle top of the slag, it can not be entangled firm and be hung out with metal steel chain, salvage time mistake
If length, break electric pole can make molten steel recarburization, cause molten steel carbon component to increase, or change the original sentence to steel grade, or cause carbon component offscale, steel
Liquid is sentenced useless, brings detrimental effect to production.
Through retrieving, Chinese patent, application publication number: 203284060 U of CN, data of publication of application: 2013.11.13, it is open
It is a kind of for electric furnace or the electrode fishing device of ladle refining furnace, the electrode fishing device include two electrodes clamping transverse arms and
Four electrodes clamp vertical arm, and each electrode clamping transverse arm fixes two electrode clamping vertical arm, and electrode clamps the company of being provided in vertical arm
Hole and pin shaft hole are connect, four electrodes are clamped by vertical arm by pin shaft and are linked together and movable, the electrode fishing device is also
Including a main chain and a secondary chain, electrode is clamped vertical arm by connecting hole and is connected to one two-by-two by the main chain and secondary chain
It rises.
Have again, Chinese patent, application publication number: 202687777 U of CN, data of publication of application: 2013.01.23 is disclosed
A kind of ladle refining furnace electrode fishing tool, the fishing tool are equipped with two electrode carrier arms, and two electrode carrier arms are connected with pin shaft,
Electrode carrier arm can be rotated around pin shaft, and one end of two electrode carrier arms connects one end of a steel wire chain respectively, two steel wire chains
For another end cap on same hanging ring, the other end of two electrode carrier arms is respectively equipped with electrode holder, and the end of two electrode holders is set respectively
Set electrode clip tooth.
When salvaging electrode, the folding of clamping limb is difficult to control above two electrode fishing device.Wherein, the first is needed
Two suspension hooks control the folding of clamping limb, operate sufficiently complex, salvage low efficiency, lead to electrode residence time mistake in molten steel
It is long, it can be to smelting molten steel carburetting；Clamping limb can not be opened using suspension hook, therefore practical application can not be carried out for second.
