When middle graphite electrode heating power, operative employee position, hair dryer (cooling) position are as shown in fig. 1, and hair dryer is to operation
Work cooling, hair dryer wind direction F can take away graphite electrode surface oxide against graphite electrode, weld 10 times or so, it may appear that figure
Graphite electrode surface shown in 3 has the oxide regions S of pit phenomenon, and graphite electrode surface pit can be deeper and deeper, until most deep
Point reaches and welds in contact surface same vertical line, it is impossible to continue to use, need replacing new graphite electrode.
Every piece of graphite electrode, which can only use 10 times, just needs replacing new graphite electrode, to guarantee subsequent lasting welding production
To go down, graphite electrode loss is very big, and it is at high cost, while replacing frequently influence production efficiency.
Summary of the invention
Technical problem to be solved in the utility model is in view of the deficiency of the prior art, and to provide one kind and mention
High graphite electrode service life reduces the welding graphite electrode structure of the replacement frequency.
In order to solve the above technical problems, the utility model adopts the following technical solution:
A kind of welding graphite electrode structure with long service life, includes pedestal and the graphite being fixed on the base electricity
Pole, the graphite electrode include bottom plate, electrode plate and welding end, and the bottom plate and welding end are connected to the electrode plate
Both ends, the bottom plate is located in the pedestal, it is characterised in that: the section that the electrode plate stretches out susceptor surface part is to become
The width in section, variable cross-section is gradually reduced from bottom plate direction to welding end direction.
The two sides side that the electrode plate stretches out susceptor surface part is cambered surface.
The two sides side that the electrode plate stretches out susceptor surface part is the first inclined-plane.
The two sides side that the electrode plate stretches out susceptor surface part is symmetrical.
The welding end includes welding end surface and two the second inclined-planes positioned at welding end surface two sides, and described two
Two inclined-planes are connect with first inclined-plane respectively, and ipsilateral first inclined-plane is identical as the inclined direction on second inclined-plane, the
The inclination angle on two inclined-planes is greater than the inclination angle on the first inclined-plane.
Angle a between first inclined-plane and base plate plane is 100-120 °.
Angle a between first inclined-plane and base plate plane is 105 °.
Card slot there are two also setting up on the electrode plate, first inclined-plane is located at card slot upper end；The electrode plate is logical
Cross card slot connection on the base.
Compared with prior art, it is variable cross-section, variable cross-section that the utility model electrode plate, which stretches out the section of susceptor surface part,
Width from bottom plate direction to welding end direction be gradually reduced.Thicker area is formed in the root that electrode plate is connect with pedestal
Domain, when graphite electrode becomes smaller because thickness occurs in oxidation reaction, thicker root slows down the speed of oxidation reaction loss, solves
Access times are few in air for welding graphite electrode, service life short problem.Mainly reach following effect:
1) one piece of graphite electrode by before can only use 10 times, improve about 13-16 times till now, graphite access times
Increase about 0.5 times.
2) reduce about 50% time of number that operative employee replaces graphite electrode.
3) shorten the change graphite time, increase production capacity.
4) equipment downtime is reduced, equipment mobility is improved.
