Abstract
The invention relates to the technical field of manufacturing of smelting equipment and discloses an electrode clamping device for an electric arc furnace. The electrode clamping device comprises a clamping support and the electrode, an annular air bag is disposed in the clamping support and is connected with a compressed air source through a pipeline and an air valve, and the electrode penetrates through a ring in the annular air bag. The clamping support is hinged with a piston rod of a driving cylinder, and the body of the driving cylinder is fixed on a base of the electric arc furnace. Compared with the prior art, the electrode clamping device for the electric arc furnace has the advantages of uniform clamping force, convenience to clamp or unclamp and reliability in electrode clamping.
Description
Technical field
The present invention relates to smelting equipment manufacturing technology field, especially a kind of device that is used for gripping on the hot stove in ore deposit electrode.
Background technology
The hot stove in ore deposit is claimed the electric arc electric furnace again, is the huge industrial furnace of a kind of power consumption, and it comes the metal smelting ore with carbon as reducing agent, is mainly used in the production ferrosilicon, ferromanganese, and ferroalloys such as ferrochrome, ferrotungsten, silicomangan are a kind of visual plants commonly used in the metallurgical industry.The hot stove in ore deposit is lacked net, water-cooling system, smoke evacuation system, loading and unloading system, brasses, compositions such as ore heat furnace transformer and various electric equipments mainly by cupola well, electrode.When having mine heat furnace smelting now, from the electric current of ore heat furnace transformer output, through electric furnace conducting systems such as too short net, brasses; Get into molten bath in the cupola well through electrode at last; Produce arc heat and resistance heat, electrode is the terminal of electric energy conversion thermal energy, is the critical component of electric furnace; In smelting production process, along with the continuous rising of bath surface in the cupola well and constantly staying of furnace charge, electrode can move axially up and down under the driving of drive unit, the furnace charge that the insertion cupola well is interior and in furnace charge, withdrawing from.For the operation that guarantees that electrode is safe and reliable aborning; Particularly along with specification, the capacity of the hot stove in ore deposit are increasing; Under the situation of its electrode weight corresponding also more and more heavier (in the load of 31500KVA stove, every electrode about about 70 tons), must carry out effective clamping to electrode; Being used for electrodes in mine hot stove at present controls electrodes in mine hot stove grip device in the system lever, taper ring type, circular cone formula and straight top hydraulic cylinder type is generally arranged.The device of these forms all exists the pressure of hold-down mechanism in the device relatively all smaller, and when the circularity inaccuracy of electrode periphery, its resultant direction can not keep pointing to the center of circle of electrode effectively; Cause the poor effect of clamping; And damage electrode easily, cause repair rate high, the time is long; Have a strong impact on metallurgical output, even also can cause other accident; In addition the device of these forms also exist compress and break away from electrode comparatively the difficulty shortcoming.
Summary of the invention
Technical problem to be solved by this invention provide a kind of to electrode exert pressure chucking power more evenly, clamping is reliable more and discharge electrode electrodes in mine hot stove grip device comparatively easily.
In order to address the above problem, technical scheme of the present invention is: this electrodes in mine hot stove grip device includes clamping bracing frame and electrode, in said clamping bracing frame, is mounted with annular air-pocket; Said annular air-pocket is connected with compressed gas source through pipeline and air valve, and said electrode passes the ring in the said annular air-pocket, and the piston rod of said clamping bracing frame and driving cylinder is hinged, and the cylinder body of said driving cylinder is fixed on the pedestal of the hot stove in ore deposit.
Owing to adopted technique scheme, the present invention compared with prior art has following beneficial effect:
1, is that the rubber-like annular air-pocket comes holding electrode owing to what adopt, is not easy to cause electrode damage, also can avoid causing the uneven situation of electrode all directions pressure because of the circularity inaccuracy of electrode periphery;
2, just can conveniently be held in electrode on the clamping bracing frame or let electrode discharge through inflation in annular air-pocket or venting from the clamping bracing frame.
Description of drawings
Fig. 1 is that master of the present invention looks generalized section;
Fig. 2 is a schematic top plan view of the present invention.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further specified:
Electrodes in mine hot stove grip device illustrated in figures 1 and 2 includes clamping bracing frame 1, is placed in the annular air-pocket 2 in the clamping bracing frame 1; Annular air-pocket 2 is connected with compressed gas source with air valve through pipeline down in working order, and electrode 4 is installed in the ring of annular air-pocket 2 and the through hole in the clamping bracing frame 1; Clamping bracing frame 1 is hinged with the piston rod of driving cylinder 3, and the cylinder body of driving cylinder 3 is fixedly connected on the pedestal of the hot stove in ore deposit.Annular air-pocket 2 is the rubber annular air-pocket; When needs clamping electrode 4, the Compressed Gas in the compressed gas source is inflated to annular air-pocket 2 through Air Valve Control; When the clip position that will change electrode 4 need move or change electrode 4, gas in the venting annular air-pocket 2, thus make electrode 4 unclamp disengaging.
