Abstract
The utility model relates to a bottom anode with a reinforced cooling copper-steel composite type water-cooling AC electric-arc furnace, comprising a conducting bar, a water-cooling electric conductor, a cooling water inlet pipe, a cooling water outlet pipe, a water box, an electrode holder and tightly pushing holder nuts, wherein, the electrode holder is clamped in the lower part of the water-cooling electric conductor. The bottom anode with the characteristics of simple structure, high safety, good cooling effect, long service life and convenient installation and disassembly can be longtime used on the AC electric-arc furnaces with various tonnages.
Description
The utility model band is forced the copper steel combined type water-cooled direct-current arc furnace bottom anode of cooling, and it is a building block of electric furnace arrangement for producing steel.
Utility model CN91206985.6 patent is the direct-current arc furnace bottom anode that band is forced cooling.Constitute by contact rod, heat radiation conducting element, cooling medium input pipe, the advantage that though simple in structure, easy to manufacture, good cooling results is arranged, can on the large-tonnage stove, use, but in use find, because the heat radiation conducting element is thicker than contact rod, during replacing end anode, can't hang out from above, must remove bottom refractory, very trouble is chronic, dismounting inconvenience.Contact rod is welded to connect with the heat radiation conducting element in addition, and during blowing out, because contact rod shrinks, weld ftractures easily, causes conduction bad during blow-on again.
The purpose of this utility model is exactly the end anode that will design a kind of simple in structure, easy to manufacture, good cooling results, remove and install conveniently, can for a long time use on the large-tonnage stove, to satisfy the needs of the continuous direct current electric arc furnace that develops.
The compound water-cooled direct-current arc of the utility model copper steel furnace bottom anode is controlled the device nut by contact rod, water-cooled electric conductor, cooling water inlet pipe, cooling water drainpipe, water box, electrode holde, push-tight and is formed.Contact rod is above the water-cooled electric conductor, and contact rod is cylindrical, adopts ingot iron or low-carbon steel material manufacturing.The water-cooled electric conductor is cylindrical copper sheathing, and external diameter is identical with contact rod, is to be threaded between the two.The outside, water-cooled electric conductor middle part is tapered, the conical surface and electrode holde internal diameter tapering are complementary, can slide up and down as required, there is screw thread in the outside, water-cooled electric conductor lower end, and control device nut coupling with push-tight, along with revolving on this nut, impel electrode holde to move up, make two conical surfaces tightly identical, guarantee that the power supply contact is good.The power supply wiring hole is arranged on the electrode holde.Cooling water inlet pipe and drainpipe and water box are one, are connected with welding manner, and the screw thread on the water box is connected with water-cooled electric conductor lower end screw thread coupling.Cooling water water inlet, drainage pipeline are common steel tube, and cooling water inlet pipe extend into the top of water-cooled electric conductor inner chamber, makes water-cooled electric conductor cavity top keep the best state of cooling.Along with the increase of stove tonnage, in order to satisfy the requirement of industrialization continuous production processes, can increase the quantity of end anode, change the diameter and the length of electrode according to the big I of stove.The profile of contact rod and water-cooled electric conductor also can be done squarely except that circle.
Be described with reference to the accompanying drawings the utility model.
Contact rod (1) and the screw thread on the water-cooled electric conductor (3) are tightened, put electrode holde (8) at tapered position, water-cooled electric conductor (3) middle part, tighten push-tight and control device nut (9), cooling water inlet pipe (4) on the water box (10) is inserted the interior top of chamber of water-cooled electric conductor (3), and tighten with the screw thread of water-cooled electric conductor (3) bottom.End anode is inserted from electrode chuck flange (7) middle part, contact rod (1) is exposed from furnace bottom, load onto felt pad (5), tighten the jackscrew on the electrode chuck flange (7), make anode location, the end.Use amorphous refractory (2) knotting on every side at contact rod (1) and water-cooled electric conductor (3), thereby end anode is fixed on the furnace bottom firmly.During replacing end anode, on the residual molten steel of furnace bottom, place reinforcing bar suspension ring, twist subjacent water box (11) and push-tight and control device nut (9), take off electrode holde (8), unclamp the jackscrew on the electrode chuck flange (7), hook the reinforcing bar suspension ring, end anode can be pulled out with crane, back out old contact rod (1) then, change clean stub.
The characteristics of the compound water-cooled direct-current arc of the utility model copper steel furnace bottom anode be simple in structure, safe and reliable, replacing and dismounting rapidly, the refractory material knotting is feasible easily, the knotting quality can be guaranteed, owing to adopted water cooling, intensity of cooling is big, effective, long service life can be used on the large-tonnage direct current electric arc furnace.
Embodiment 1:
From accompanying drawing as can be seen, get a diameter 80mm, the cylindrical mild steel contact rod of length 200mm (1), one end car of contact rod (1) becomes convex shape and is threaded, and this contact rod (1) and top are that the water-cooled electric conductor (3) of concave shape (there is screw thread the groove inboard) external diameter 80mm is threaded.The bottom that cooling water inlet pipe (4) on the water box (10) passes water-cooled electric conductor (3) extend into the top of the cavity of water-cooled electric conductor (3), water box (10) screw thread is connected with water-cooled electric conductor (3) lower end screw thread, seal washer is equipped with in the junction, and cooling water inlet pipe (4) and drainpipe (11) are welded to connect with water box (10).By the location of the jackscrew on the electrode chuck flange (7), between jackscrew and the water-cooled electric conductor (3) felt pad (5) is arranged between water-cooled electric conductor (3) and the furnace shell, the fastening and insulation with furnace shell, the amorphous refractory (2) of tiing a knot around the end anode.Electrode holde (8) is controlled device nut (9) by push-tight and is closely cooperated with water-cooled electric conductor (3).The utility model water is as cooling medium.On probation having reached can also continue more than 300 stoves to use on 1.5 tons of direct current electric arc furnaces.
Embodiment 2: contact rod (1) is the four-prism of 80 * 80 * 200mm, and water-cooled electric conductor (5) cross section, top is the square of 80 * 80mm, and contact rod (1) is used the ingot iron manufacturing, and other are identical with embodiment 1.
