Embodiment 1

[0039] Example 1: Such as Figure 10-Figure 11 As shown, an electrode connection mark positioning method includes the following steps:

[0040] S1: First determine the starting point A of the electrode cone internal thread and the center B of the electrode end surface;

[0041] S2: Then determine the intersection points C and D between the connecting point A and B and the outer circumference of the electrode;

[0042] S3: Finally determine the point close to point A among the two points C and D, and use this point as the vertex to mark the triangle.

Embodiment 2

[0043] Example 2: Such as Figure 1-Figure 9 As shown, an electrode connection marking positioning device includes an elongated fixing plate 1, a triangular marking template 8, a threaded block A2 and a threaded block B3. One end of the fixing plate 1 is provided with a threaded hole 11, and a bolt 9 and a triangular mark are provided The template 8 is connected vertically, the other end of the fixing plate 1 and the threaded block B3 are provided with grooves 7 and threaded holes 11, the fixing plate 1 and the threaded block B3 are detachably connected by bolts 9 and positioning keys 12; A sliding groove 6 is provided in the middle, a sliding key 5 is correspondingly provided in the sliding groove 6 and the two are fixed by a locking ball head bolt 10, and the sliding key 5 and the threaded block A2 are connected by a bolt 9.

Abstract

The present invention discloses an electrode connection mark positioning method and device, belonging to the technical field of graphite electrode connection. The objective of the invention is to solve the technical problem that a current mark method cannot solve the problem that electrode butting is not fixed caused by wearing of a cutter. The method comprises the following steps of: determiningan electrode internal taper thread cutting point A and an electrode end face circle center B; determining intersection points C and D of a ligature of the A and the B and an external circumference surface of the electrode; and finally, determining a point, close to the point A, in the C and the D, and obtaining a connection mark. The device comprises an elongated fixed plate, the fixed plate is provided with a triangular mark template, a screw thread block A and a screw thread block B, an included angle between the triangular mark template and the fixed plate is 90 degrees, and after the screwthread block A and the screw thread block B are screwed, a position where the triangular mark template is located is a position requiring being marked. The electrode connection indication positioningmethod and device are simple in structure and convenient to use, and employ a mark positioner to rapidly complete positioning of a triangular mark, and therefore, the electrode connection indicationpositioning method and device are accurate in positioning and cannot be influenced by wearing of the cutter.

Description

Technical field [0001] The invention relates to the technical field of graphite electrode connection, in particular to an electrode connection marking positioning method and device. Background technique [0002] Graphite electrode products are used in electric furnace steelmaking production. It is not only a conductor, but also a heating medium, which generates arc heat between the electrode and the steel material to achieve the purpose of smelting. In the use of electrode products, there will be phenomena such as joint breakage, tripping, and electrode hole rupture. These unfavorable phenomena occur, and the electrode connection is not fastened as one of the main reasons. [0003] At present, in order to ensure the electrode connection is fastened and prevent the electrode from falling off or breaking due to the loose connection when the electrode is connected, the electrode manufacturer is generally required to draw a drawing on the outer circle of both ends of the electrode. A ...
