Technical field
The present invention relates to graphite electrode interconnection technique fields, and in particular to a kind of electrode connection mark localization method and dress
It puts.
Background technology
Graphite electrode product produces for electric furnace steel making, it is electric conductor and thermophore, between electrode and steel material
Arc heat is generated, to achieve the purpose that melting.Electrode product is present with phenomena such as joint breaking, dropout, electrode hole rupture in,
The generation of these bad phenomenons, it is one of main cause that electrode connection, which does not fasten,.
At present, domestic and international electric-arc furnace steelmaking factory fastens in order to ensure electrode connects, avoids because connecting not in electrode continued access
Electrode delamination or breakage phenomenon caused by tightly, common demands electrode production producer draw connection mark at the outer circle of electrode both ends
Show（Generally equilateral triangle）, electrode attended operation work to be instructed to apply science torque, reach mark docking, electrode connection fastening
Purpose.
It is existing mark way be：Daily before electrode normal process, first process two electrodes and do connection experiment, fastening
Two electrode tips outer circles at, spray two equilateral triangles of picture, and make its tip to tip, two electrodes are then unscrewed, in outer circle
Place measures two equilateral triangles point and the relative arc length of hole internal thread cutting point, after finally determining will machined electrode connection
Marker location.But as face cutter is worn, equilateral triangle point and the relative arc length of screw thread cutting point can change, and
This gradual variation is such as unable to synchronous adjustment, then connection mark is often caused intact cannot to dock, can not the normal company of guidance
It connects operation or even not tight and electrode delamination the accident of connection is caused to occur.

90 °, the threaded block A and threaded block B are equipped with circular cone external screw thread corresponding with electrode conical inner screw thread and on whole circle
After a part is so that threaded block A and threaded block B be tightened, warning triangle template position and electrode internal thread cutting point pair
The outer circle position consistency answered.
Preferably, the arc-shaped plate of the warning triangle template and internal diameter size and electrode outer diameter are in the same size；The triangle
Template is marked to be equipped with tri-angle-holed.
Preferably, the central angle corresponding to the warning triangle template is 28 °.
Preferably, the one end of the fixed plate away from the warning triangle template is connected with threaded block B by screw and key connects
It connects.
Preferably, sliding shoe is equipped between the fixed plate and the threaded block A, the slide key is consolidated with the threaded block A
Fixed connection and with the fixed plate dismantling connection.
Preferably, the fixed plate is equipped with and the corresponding sliding groove of the sliding shoe.
Preferably, the whole circle number of turns is enclosed for 2-3.
Preferably, the central angle corresponding to the threaded block A and threaded block B is 30 °.
Inventor is by the discovery that studies for a long period of time：Two electrodes have been reached by transition joint to be fastenedly connected, and two spiral shell of connector
The line conical surface is snapped through by centre to be crossed, and essence has become a complete helix；And two electrode sheets being connected by screw thread
Body, their two helixes are a complete helix also by whole helix drop-over of connector, as long as so finding
The screw thread cutting point of each electrode hole in the corresponding outer circle position spraying connection mark of this cutting point, will be overcome because cutter is ground
Deviation is indicated caused by damage.
Compared with prior art, the method have the benefit that：
1st, localization method accurate positioning of the invention, accuracy are high, tool wear can be overcome to cause existing marker method completely
Error, suitable for large-scale promotion application.
2nd, the device of the invention is simple in structure, easy to use, can be rapidly completed what triangle indicated using this mark locator
Positioning, and accurate positioning, from the influence of tool wear.
3rd, in the present invention, threaded block A and threaded block B are the part on whole N circles, so spiral shell on threaded block A and threaded block B
Line screw thread cutting point starts to screw in electrode internal thread cutting point, after rotating whole N circles fixation, warning triangle template institute fixed position
It is exactly the corresponding outer circle position of electrode internal thread cutting point, that is, marker location.
4th, it is detachable between the warning triangle template of present invention mark locator, threaded block A and threaded block B and fixed plate
Mode is fixedly connected with, warning triangle template, threaded block A and the threaded block B of different size parameter can be adjusted according to actual demand.
5th, matched slide key and sliding groove in the present invention can change threaded block A and threaded block B according to actual demand
Spacing, to adapt to Different electrodes threaded hole.
