Description
Technical field
The present invention relates to a kind of metal smelt technology, particularly relate to a kind of dummy electrode docking facilities.
Background technology
The resistance heat that metal electroslag furnace (having another name called resmelting electrode process units) produces when being and utilize electric current by slag carries out a kind of metallurgical equipment of melting as thermal source, its structure mainly includes the entirety crystallizer in oven-like, is positioned at the column of crystallizer side, column is provided above horizontal cantilever, and horizontal cantilever is just being provided with, by electrode bar chuck, the electrode bar extending down into crystallizer to crystallizer.Wherein electrode bar includes being positioned at the dummy electrode of upper end and is positioned at the Electrode for remelting of lower end, and wherein Electrode for remelting uses and is refined material itself and makes, and progressively melts in consumption is flowed into crystallizer and forms steel ingot, therefore be also called consutrode in smelting process.
The conventional preparation method of the consutrode of electroslag refining furnace is to use the Electrode for remelting of cast and the electric welding seam mutually of ready both dummy electrodes, the more difficult accurate control of concentricity both when its difficulty of this technique is to weld, once the two concentricity inaccuracy, under after consutrode suspension at Gravitative Loads, the gap of its tail end distance crystallizer wall is the most uneven, even part touches wall, the position that gap so can be made after power transmission the least is beaten electric current at arc, tactile wall and is directly conducted along crystallizer wall, consequence is to puncture or melt the crystallizer wall at this position, causes leakage accident.After especially adopting atmosphere protection sealing structure, the concentricity to electrode is had higher requirement.It is usually at present when consutrode welds with dummy electrode with the naked eye or uses certain work die clamper to position concentricity, these method positioning precisions are low, regulation is difficult to, and in operation, consutrode is often poor because welding concentricity with dummy electrode, is necessary for cutting down electric welding again, and its operation is wasted time and energy, efficiency is low, seriously restricts production efficiency.
China's patent ZL201310683642.1 once disclosed the melting and welding method the most mutually of a kind of electroslag refining furnace consutrode and dummy electrode.The method specifically includes following steps: it is standby that (1) makes dummy electrode；(2) determine that dummy electrode injects the length in below ingot mould molten steel face, carry out labelling；(3) cast consutrode, when molten steel is poured into away from ingot mould suitable for reading 400～200mm, inserts the above-mentioned dummy electrode prepared, fine setting dummy electrode and ingot mould concentricity the most straight down in ingot mould centre suitable for reading, and meanwhile, pourer takes normal feeding to operate；(4) demoulding.This inventive method is by together with mutual to consutrode and dummy electrode fusion welding, and faying face is big, and firm welding is tight, does not loosens, and the problem that there is not loose contact；But this mutual fusion welding process uses manual operation, still having labor intensity big, safety is low, and efficiency is low, the centering weak effect defect such as cause the electrode axiality for preparing low, affects subsequent smelting safety and quality.
Summary of the invention

As optimization, described electrothermal module is a few heating wire structures that the cone barrel internal chamber wall around dummy electrode sleeve bottom is arranged.
So there is simple in construction, the advantage being heated evenly, it is to avoid inequality of being heated causes molten steel splash and the problem affecting joint quality.
As optimization, described insertion controlling organization includes the vertical adjusting gear rack being fixedly installed on abutment sleeve outer surface, adjusting gear rack can slide up and down to be matched with on dummy electrode sleeve in the regulation breach vertically offered, insert controlling organization and also include one and the regulation gear of adjusting gear rack engagement, extending transversely through at regulation gear axis and be fixedly installed regulation rotating shaft, regulation rotating shaft is installed in rotation in two the rotating shaft mounting seats being fixed on dummy electrode sleeve outer surface.
So, rely on regulation gear and the cooperation of adjusting gear rack, before Electrode for remelting waters mold casting, regulation dummy electrode is upwards positioned at Electrode for remelting and waters above mold casting metal line, after casting, control to adjust dummy electrode again to be inserted downwardly into Electrode for remelting and water in mold casting metal line, the i.e. available required consutrode of the rear demoulding to be solidified.Use this insertion controlling organization to have a simple in construction, easy to adjust fast, reliable and stable, the advantages such as safety is good.
As optimization, regulation rotating shaft one end is provided with regulation handle.So, the carrying out of convenient regulation, improve safety.
As optimization, between regulation handle and regulation roller end, it is provided with worm type of reduction gearing, is used for realizing regulating self-locking.Use the locking function that carries of worm gear screw speed device, can protection device up-down adjustment time will not catastrophic failure, also maintain certain distance with molten steel during this device operative, improve operation safety.
As optimization, dummy electrode sleeve outer surface is positioned at the side of regulation breach and is additionally provided with regulation marking line.So, convenient by observing regulation marking line, it is judged that adjusting position so that regulation is inserted accurately and reliably.
In sum, the present invention has simple in construction, easy to operate, and safety is good, and production efficiency is high, prepares the advantages such as electrode quality is good.
