Description
Technical field
This utility model relates to graphite electrode technical field, especially a kind of novel graphite resistor rod.
Background technology
Graphite electrode development time is the longest, and it is disadvantageous in that high-temperature oxidation resistance is poor, is using
Cheng Zhong, graphite electrode oxygen easily and in air reacts and consumes in vain, simultaneously as graphite electrode exists
During use, it is common that directly use with bolt overlap joint copper bar, assemble complex and reliability is the best,
Need to improve.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, it is provided that a kind of novel graphite resistor rod,
Assembling is simple, and non-oxidizability and thermal diffusivity are preferable.
For reaching above-mentioned purpose, the technical solution of the utility model is: a kind of novel graphite resistor rod, including circle
The body of cylindricality, described body central is provided with the through hole run through up and down, the circumferential uniform circular groove in described through hole periphery,
The arc groove of the outer rim uniform connection of circumference of described body and outer arcuate groove, in described arc groove outside grafting
Copper bar, the upper end of described outer copper line exceeds top the connecting lead wire dish of arc groove, under described lead wire tray
Being provided with the center copper bar that laminating through hole extends downwards at centre of surface, the bottom of described center copper bar is provided with outwards
Extend and the flange of body bottom portion of fitting, be filled with carbon black filler in described circular groove, described carbon black filler sets
The copper cash extending to lead wire tray upper end, the outer surface of described body is had to be provided with anti oxidation layer.
The length of described arc groove is more than the length of outer arcuate groove.
The both sides of described outer arcuate groove form internal arcuate groove and carry out the block edge of semi-surrounding.
Described anti oxidation layer is silicon nitride ceramics layer.
The beneficial effects of the utility model are: assembling is simple, by silicon nitride ceramics layer as anti oxidation layer,
Graphite electrode is difficult to react with the oxygen in air and consume；Carbon black filler and the setting of its internal copper cash,
Both can strengthen the intensity of body, the drawback that in graphite electrode, CURRENT DISTRIBUTION is uneven can have been improved again；Graphite electrode
Perfect heat-dissipating, stable and reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 be in Fig. 1 A-A to sectional view.
In figure: body 1, through hole 11, circular groove 12, arc groove 13, outer arcuate groove 14, block edge 15,
Outer copper line 2, lead wire tray 3, center copper bar 4, flange 41, carbon black filler 5, copper cash 6, anti oxidation layer 7.
Detailed description of the invention
Below by embodiment, and combine accompanying drawing, the technical solution of the utility model is made the most concrete
Explanation.
As shown in Figure 1 and Figure 2, a kind of novel graphite resistor rod, including cylindrical body 1, described body 1
Center is provided with the through hole 11 run through up and down, the peripheral circumferential uniform circular groove 12 of described through hole 11, described body 1
The outer rim circumference arc groove 13 of uniform connection and outer arcuate groove 14, circular groove 12 is positioned at through hole 11 and inner arc
Between shape groove 13, the length of described arc groove 13 is more than the length of outer arcuate groove 14, described outer arcuate groove
The both sides of 14 form internal arcuate groove 13 and carry out the block edge 15 of semi-surrounding, and outer arcuate groove 14 is positioned at arc groove
The middle of 13, grafting outer copper line 2 in described arc groove 13, outer copper line 2 is plugged into arc groove always
The bottom surface of 13, outer copper line 2 cross section is the circular arc consistent with arc groove 13, it is not necessary to bolt is fixed, assembling
Convenient.
The upper end of described outer copper line 2 exceeds top connecting lead wire dish 3, outer copper line 2 He of arc groove 13
Lead wire tray 3 can be welded and fixed, and lead wire tray 3 can not move down, the lower surface center of described lead wire tray 3
Place is provided with the center copper bar 4 that laminating through hole 11 extends downwards, and center copper bar 4 inner hollow defines body 1
Louvre so that this utility model perfect heat-dissipating, stable and reliable.
The bottom of described center copper bar 4 is provided with the flange 41 bottom the body 1 that stretches out and fit, flange 41
Lead wire tray 3 can be made not will be shifted up.
It is filled with carbon black filler 5 in described circular groove 12, described carbon black filler 5 is provided with and extends to lead wire tray 3
The copper cash 6 of upper end, the copper cash 6 passing lead wire tray 3 upper end is welded and fixed with lead wire tray 3, described body 1
Outer surface is provided with anti oxidation layer 7, and described anti oxidation layer 7 is silicon nitride ceramics layer, carbon black filler 5 and copper cash 6
Setting both strengthened the intensity of body 1, the drawback that in graphite electrode, CURRENT DISTRIBUTION is uneven can be improved again.
