This joint not only reduced the electrode and connect between contact resistance value, improved frictional force moreover, the problem having solved easy scaling loss and breaked.
Description
Technical field
This utility model belongs to graphite electrode connector technical field, is specifically related to a kind of ultrahigh power graphite electricity
Pole joint.
Background technology
Graphite electrode in use can gradually use up, and becomes shorter and shorter.In large scale industry production and application,
Need to use after from beginning to end to two or many electrodes, to reduce the frequency changed that stops production.Conventional method
It is to use Graphite nipple to connect two electrodes.Graphite electrode is used for electric furnace steel making.In leading to that electric furnace steel making produces
In electric process, electrode column electrode is mainly passed through electrode by joint with the electric current of joint connection position, leads to simultaneously
Crossing the electric current density at nipple orifice screw thread to increase, the maximum of this position electric current density is in the maximum of bond diameter
Place, is electric current conduction and the weakest link of heat conduction, the contact surface temperature between electrode and joint in electrode column
Degree raises, and joint is not easy in medium and small heat radiation, and electrode is limited with the coefficient of heat conduction of joint, thus exists
Electrode defines the hot load higher than other positions with the connecting portion of joint, is very easy to make this position produce
Hot-spot, beat arc, scaling loss, coming off even fractures, and causes graphite electrode in electric furnace steel making production process to disappear
Consume higher.
Utility model content
For solving the easy scaling loss that existing graphite electrode nipple exists and the problem interrupted, this utility model carries
Going out a kind of ultrahigh power graphite electrode joint, this joint not only reduces the contact resistance between electrode and joint
Value, and improve frictional force, the problem solving easy scaling loss with interrupting.
The technical solution of the utility model is achieved in that
A kind of ultrahigh power graphite electrode joint, in being positioned at including the first Rotary-table, the second Rotary-table and one
Between cylinder, the big bottom surface of described first Rotary-table and the big bottom surface of described second Rotary-table respectively with institute
Stating the cylindrical involutory connection of upper bottom surface, the axis of three is located on the same line, described cylinder
Diameter and the described cylindrical high length ratio of bottom surface be 6-10:1, right on the described cylindrical face of cylinder
Claiming to be provided with two installing holes, the table top of described first Rotary-table is all provided with on the table top of described second Rotary-table
Being equipped with external screw thread, described externally threaded surface-coated has oildag.
Further, the size of described first Rotary-table and described second Rotary-table is equivalently-sized.
The beneficial effects of the utility model:
1, on the table top of the Rotary-table of ultrahigh power graphite electrode joint of the present utility model, externally threaded surface is coated with
It is covered with oildag, decreases contact resistivity between electrode and joint, also increase the contact friction between them
Power so that contact surface has good electric conductivity, graphite electrode columns is in joint and electrode connecting portion position conduction effect
The best, it is not easy to occur overheated, beat arc, scaling loss, come off even breakage phenomenon, electric furnace steel making produce stone
Electrode ink consumption reduces.
2, it is symmetrically arranged with two installing holes on the face of cylinder to be easy to connect dismounting clamping apparatus, is hardly damaged round table surface
Screw thread.The length ratio that the diameter of cylindrical bottom surface is high with it is 6-10:1, improves the anti-of joint and fractures
Intensity, reduce the probability of electrode fracture loss of sheet.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below by right
In embodiment or description of the prior art, the required accompanying drawing used is briefly described, it should be apparent that below,
Accompanying drawing in description is only embodiments more of the present utility model, for those of ordinary skill in the art,
On the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the cross-sectional view of this utility model ultrahigh power graphite electrode joint.
Accompanying drawing indicates: 1, the first Rotary-table, the 2, second Rotary-table, 3, cylinder, 4, installing hole, 5,
External screw thread.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, to the technical side in this utility model embodiment
Case is clearly and completely described, it is clear that described embodiment is only that this utility model part is real
Execute example rather than whole embodiments.Based on the embodiment in this utility model, ordinary skill people
The every other embodiment that member is obtained under not making creative work premise, broadly falls into this utility model
The scope of protection.
With reference to Fig. 1, a kind of ultrahigh power graphite electrode joint, including first Rotary-table the 1, second Rotary-table 2
With a cylinder 3 being positioned at centre, the size of the first Rotary-table 1 is equivalently-sized with the second Rotary-table 2.
The big bottom surface of the first Rotary-table 1 and the big bottom surface of the second Rotary-table 2 respectively with the upper bottom surface of cylinder 3
Involutory connection, the axis of three is located on the same line.The diameter of the bottom surface of cylinder 3 and cylinder 3
High length ratio be 6-10:1.Two installing holes 4 it are symmetrically arranged with on the face of cylinder of cylinder 3, first
Being provided with external screw thread 5 on the table top of Rotary-table 1 and the table top of the second Rotary-table 2, the surface of external screw thread 5 is coated with
It is covered with oildag.
On the table top of the Rotary-table of ultrahigh power graphite electrode joint of the present utility model, the surface of external screw thread 5 is coated with
It is covered with oildag, decreases contact resistivity between electrode and joint, also increase the contact friction between them
Power so that contact surface has good electric conductivity, graphite electrode columns is in joint and electrode connecting portion position conduction effect
The best, it is not easy to occur overheated, beat arc, scaling loss, come off even breakage phenomenon, electric furnace steel making produce stone
Electrode ink consumption reduces.It is symmetrically arranged with two installing holes 4 on the face of cylinder and is easy to connect dismounting clamping apparatus, no
The screw thread of fragile round table surface.The length ratio that the diameter of cylindrical bottom surface is high with it is 6-10:1, improves
The anti-intensity fractureed of joint, reduces the probability of electrode fracture loss of sheet.
