Abstract
The utility model relates to a new structure for mounting a graphite electrode and a copper chuck. The new structure comprises the vertically arranged graphite electrode, a horizontally arranged electrode cross arm, the copper chuck arranged between the graphite electrode and the electrode cross arm, and a U-shaped clamp ring for connecting the graphite electrode and the electrode cross arm in a fastening manner, wherein a concave face of a half slot of the copper chuck is in matched connection with an external circumferential surface of the graphite electrode, an end part of the electrode cross arm, close to the copper chuck, is vertically provided with a flat plate, four corners on the surface of the copper chuck, close to the graphite electrode, are respectively provided with a concave step, and the concave steps of the copper chuck are detachably connected with the flat plate through horizontally arranged screws. By adoption of the technical scheme, because the screws for fixedly connecting the copper chuck and the electrode cross arm are far away from a contact face between the graphite electrode and the copper chuck, and holes are bored in the concave steps arranged on the four corners of the copper chuck for fixation, so that a firmer property is achieved. According to the utility model, the screws cannot be scorched due to electric arcs, better convenience is brought to maintenance and detachment, and the service life of the copper chuck is prolonged.
Description
Technical field
The utility model belongs to the refractory material production technical field, and particularly a kind of graphite electrode and copper chuck are installed new construction.
Background technology
The original-pack copper dop of the electric furnace shop of refractory material is rectangular shape, copper dop and graphite electrode contact-making surface are the half slot shape, another opposite face of copper dop is the plane, this plane contacts and is fixed on the electric-pole horizontal arm front end face with the electric-pole horizontal arm front end face, is fastenedly connected by U-shaped snap ring between graphite electrode and the electric-pole horizontal arm.Six side's screws entered and utmost point transverse arm front end face built-in nut secure bond from the half slot concave surface in the fixed form of copper dop and electric-pole horizontal arm front end face adopted 4, and interior six side's screw terminals get deeply stuck in the half slot concave surface of copper dop.
In actual use, the half slot concave surface of copper dop contacts with graphite electrode and badly often can produce electric arc.Electric arc can burn the copper in the copper dop, flows into the screw place and clings screw, and electric arc directly crumples screw sometimes.The copper dop is loosening, and is very difficult when causing dismounting, maintenance and polishing dop.Also often because maintenance is inconvenient, not in place, monoblock copper dop is scrapped, caused the wasting of resources, what also impact was produced carries out continuously.
The utility model content
The utility model provides a kind of graphite electrode and copper chuck of being convenient to dismounting and maintenance that new construction is installed in order to solve weak point of the prior art.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: graphite electrode and copper chuck are installed new construction, the graphite electrode that comprises vertical setting, horizontally disposed electric-pole horizontal arm, the U-shaped snap ring that is located at the copper chuck between graphite electrode and the electric-pole horizontal arm and graphite electrode and electric-pole horizontal arm are fastenedly connected, half slot concave surface and the graphite electrode external peripheral surface of copper chuck are connected, described electric-pole horizontal arm vertically is provided with one flat plate in the end of closing on the copper chuck, the copper chuck is respectively equipped with the concave station rank in the position at four angles, surface of closing on graphite electrode, and the copper chuck removably connects by horizontally disposed screw and flat board at place, concave station rank.
Adopt technique scheme, the screw that is used for the copper dop is fixedly connected with electric-pole horizontal arm is away from the contact-making surface between graphite electrode and the copper chuck, and is fixing, more firm in the concave station rank boring that four jiaos of copper chucks arrange.Can be because of electric arc the calcination screw, repair demolition is more convenient, has prolonged copper dop service life.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view of Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2, graphite electrode of the present utility model and copper chuck are installed new construction, the graphite electrode 1 that comprises vertical setting, horizontally disposed electric-pole horizontal arm 2, the U-shaped snap ring 4 that is located at the copper chuck 3 between graphite electrode 1 and the electric-pole horizontal arm 2 and graphite electrode 1 and electric-pole horizontal arm 2 are fastenedly connected, the half slot concave surface of copper chuck 3 and graphite electrode 1 external peripheral surface are connected, electric-pole horizontal arm 2 vertically is provided with one flat plate 5 in the end of closing on copper chuck 3, copper chuck 3 is respectively equipped with concave station rank 6 in the position at four angles, surface of closing on graphite electrode 1, and copper chuck 3 removably connects with dull and stereotyped 5 by horizontally disposed screw 7 at 6 places, concave station rank.Flat board 5 is made into integration with electric-pole horizontal arm 2, lengthens up and down respectively in electric-pole horizontal arm 2 ends to get final product.
The screw 7 that is used for copper dop 3 is fixedly connected with electric-pole horizontal arm 2 is worn screw 7 in 6 borings of 3 four jiaos of concave station rank that arrange of copper chuck fixing, more firm away from the contact-making surface between graphite electrode 1 and the copper chuck 3.Can be because of electric arc calcination screw 7, repair demolition is more convenient, has prolonged 3 service lifes of copper dop.
