Abstract
The utility model discloses a forging-type water-cooled bottom ring, which comprises a water-cooled bottom ring body. A horizontal cooling water channel and a longitudinal cooling water channel are arranged in the water-cooled bottom ring body; and plugs with corresponding aperture are respectively arranged at water inlets and water outlets of the horizontal cooling water channel and the longitudinal cooling water channel. The diameter of the horizontal cooling water channel and the longitudinal cooling water channel is 25mm. In the utility model, the deep hole drilling is replaced for molding after desanding of the original casting bottom ring cooling water channel, so that the service life of the bottom ring is prolonged. As the deep hole drilling is replaced for the pressing molding of the original casting product, the water cooling effect is much better, not only the using temperature of the bottom ring is reduced, but also the electric energy loss of contact members is reduced, the using effect of the bottom ring is improved, and the service life is prolonged.
Description
Technical field
The utility model belongs to the metallurgical electric furnace field, is specifically related to a kind of forging formula water cooling bottom ring, is used for cooling off the conducting heavy current contact element of composite electrode holder.
Background technology
Bottom part ring is the main water-cooled part part of composite electrode holder in the furnace equipment, and this technology is by the exploitation of Norway Ai Ken company, and last century, the nineties China at first introduced this technology on furnace of calcium carbide.Its weak point is: traditional bottom part ring adopts casting technique to make always, so the density of former bottom part ring material copper casting is not high, the water channel desanding not to the utmost; Add that sand holes, defective such as loose can appear during bottom part ring in casting, cellular fault often appears in the bottom part ring surface, has the hidden danger of percolating water at any time, and influence cooling effect, the useful life of reduction electric conductor contact element.Former casting bottom part ring cooling water channel is by the shakeout aftershaping, or in give and bury seamless steel pipe, under big electric current high-intensity magnetic field, can form eddy current, magnetic hysteresis, cause electric energy loss, reduced bottom part ring useful life.
Summary of the invention
The purpose of this utility model is to avoid above-mentioned weak point and provides a kind of electric energy loss that eddy current, magnetic hysteresis cause under the big electric current high-intensity magnetic field of having eliminated, the forging formula water cooling bottom ring that has prolonged bottom part ring useful life.
A kind of forging formula water cooling bottom ring described in the utility model, comprise water cooling bottom ring body, it is characterized in that: be provided with horizontal cooling-water duct and vertical cooling-water duct in water cooling bottom ring body interior, be furnished with the plug of respective aperture respectively at each water inlet and the delivery port of horizontal cooling-water duct and vertical cooling-water duct.
The diameter of above-mentioned horizontal cooling-water duct and vertical cooling-water duct is 25mm.
The utility model has replaced former casting bottom part ring cooling water channel by the shakeout aftershaping to beat deep hole, or in give and bury seamless steel pipe, eradicated the electric energy loss of eddy current, magnetic hysteresis under the big electric current high-intensity magnetic field, prolonged bottom part ring useful life.Because replace compression moulding after the former casting technique to beat deep hole, the cooling effect of Gu Shui is much better, has both reduced the serviceability temperature of bottom part ring, has reduced the electric energy loss of contact element again, has improved the result of use of bottom part ring, has prolonged useful life thereupon.
Description of drawings
Fig. 1 is the bottom part ring artwork,
Fig. 2 is the bottom part ring artwork of forging forming.
Embodiment
Below in conjunction with most preferred embodiment the utility model is further set forth:
With Fig. 1 is example, and forging processing thickness with the T2 red copper is the forging formula water cooling bottom ring body 1 of 142mm, and 339mm is of a size of development size among the figure.Take the least important seat at a square table after around the processing to cooling-water duct 2 and vertical cooling-water duct 3, its diameter is 25mm.Each hole is mixed the plug of respective aperture size welding is shut in the water hole, prevents to leak.
With Fig. 2 is example, forges formula water cooling bottom ring press forging forming among the figure, and the screw thread hole depth 25mm of 8 M10 is arranged on the bottom part ring, is intended to be insulating part and matches, thereby make bottom part ring and protect screen and play insulating effect.After machining, must be through the hydraulic test of 0.8Mpa, voltage stabilizing is after 15 minutes, and the surface must no any seepage phenomenon.
One phase electrode is with 4 or 6 or 8 bottom part ring, and obvolvent is a circumference, protects screen by insulating part and stainless steel and is connected, and plays a protective role, and is connected with 8 groups or 12 groups or 16 groups of core conductive component conducting elements.Avoided high-temperature dust harm, thus long service life, and also the conducting element of wearing and tearing is repeatedly reusable after repairing.Compress because of adopting spring to add bolt between conducting element and the electrode shell, thus the more closely not starting the arc of contact, current stabilization.
Claims (2)
1, a kind of forging formula water cooling bottom ring, comprise water cooling bottom ring body (1), it is characterized in that: be provided with horizontal cooling-water duct (2) and vertical cooling-water duct (3) in water cooling bottom ring body (1) inside, be furnished with the plug of respective aperture respectively at each water inlet and the delivery port of horizontal cooling-water duct (2) and vertical cooling-water duct (3).
2, forging formula water cooling bottom ring according to claim 1 is characterized in that: laterally the diameter of cooling-water duct (2) and vertical cooling-water duct (3) is 25mm.
