Abstract
The utility model relates to the manufacture technique field of smelting equipment, and discloses an electrode holding device of a submerged arc furnace. The electrode holding device comprises a clamping support frame and an electrode, wherein an annular airbag is arranged in the clamping support frame; and the annular airbag is connected with a compressed air source through a pipeline and an air valve, the electrode penetrates through a ring in the annular airbag, the clamping support frame is hinged with a piston rod of a driving cylinder, and a cylinder body of the driving cylinder is fixed on a pedestal of the submerged arc furnace. Compared with the prior art, the electrode holding device has the advantages that the clamping force is uniform, clamping or releasing is convenient, and the electrode holding is reliable.
Description
Technical field
The utility model relates to smelting equipment manufacturing technology field, especially a kind of device for gripping electrode on the mineral hot furnace.
Background technology
Mineral hot furnace claims again the electric arc electric furnace, is the huge industrial furnace of a kind of power consumption, and it comes the metal smelting ore with carbon as reducing agent, mainly for the production of ferrosilicon, and ferromanganese, the ferroalloys such as ferrochrome, ferrotungsten, silicomangan are a kind of visual plants commonly used in the metallurgical industry.Mineral hot furnace is mainly by cupola well, electrode, short net, water-cooling system, smoke evacuation system, loading and unloading system, brasses, the compositions such as ore heat furnace transformer and various electric equipments.During existing mine heat furnace smelting, from the electric current of ore heat furnace transformer output, through electric furnace conducting systems such as too short net, brasses, enter molten bath in the cupola well by 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, inserts the furnace charge in the cupola well and withdraws from furnace charge.In order to guarantee aborning safe and reliable operation of electrode, particularly along with specification, the capacity of mineral hot furnace are increasing, in the situation of its electrode weight corresponding also more and more heavier (in the load of 31500KVA stove, every electrode is approximately about 70 tons), must carry out effective clamping to electrode; The electrodes in mine hot stove grip device of controlling in the system for electrodes in mine hot stove at present generally has lever, taper ring type, circular cone formula and straight top hydraulic cylinder type.The device of these forms all exists the pressure of hold-down mechanism in the device relatively all smaller, 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 easily damage electrode, cause repair rate high, the time is long, have a strong impact on metallurgical output, even also can cause other accident; Also there is compression in the device of these forms and breaks away from the comparatively shortcoming of difficulty of electrode in addition.
The utility model content
Technical problem to be solved in the utility model provide a kind of to electrode exert pressure chucking power more evenly, clamping is more reliable and discharge comparatively easily electrodes in mine hot stove grip device of electrode.
In order to address the above problem, the technical solution of the utility model is: this electrodes in mine hot stove grip device includes clamping bracing frame and electrode, is mounted with annular air-pocket in described clamping bracing frame; Described annular air-pocket is connected with compressed gas source by pipeline and air valve, and described electrode passes the ring in the described annular air-pocket, and the piston rod of described clamping bracing frame and driving cylinder is hinged, and the cylinder body of described driving cylinder is fixed on the pedestal of mineral hot furnace.
Owing to having adopted technique scheme, the utility model compared with prior art has following beneficial effect:
1, is to have flexible annular air-pocket to come holding electrode owing to what adopt, is not easy to cause electrode damage, also can avoid causing the inhomogeneous situation of electrode all directions pressure because of the circularity inaccuracy of electrode periphery;
2, just can conveniently electrode be held on the clamping bracing frame or allow electrode discharge from the clamping bracing frame by inflation in annular air-pocket or venting.
Description of drawings
Fig. 1 is that master of the present utility model looks generalized section;
Fig. 2 is schematic top plan view of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model 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 lower in working order to be connected with compressed gas source with air valve by pipeline, 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 mineral hot furnace.Annular air-pocket 2 is the rubber annular air bag; When needs clamping electrode 4, by Air Valve Control the Compressed Gas in the compressed gas source is inflated to annular air-pocket 2; When the clip position that will change electrode 4 need to move or change electrode 4, venting annular air-pocket 2 interior gases, thus make electrode 4 unclamp disengaging.
