Abstract
The invention discloses a processing method of graphite electrodes. The method adopts the mode of leading large current into a closed loop formed through tandem connection of graphite electrodes of two adjacent furnaces. The method is characterized in that furnace head electrodes adopt a mobile transformer car power supply mode, and furnace tail parts adopt mobile hydraulic current-conducting plate short-circuit electrodes; graphite electrode surface cracks caused by local temperature non-uniformity during discharge are removed by adopting a discharge resistance adjusting method between the graphite electrodes; a furnace body leakage preventing separation wall is adopted as the furnace body separation wall, thus eliminating leakage of the two adjacent furnaces.
Description
Technical field
The present invention relates to a kind of working method of graphitized electrode, this graphitized electrode is widely used in metallurgy industry.
Background technology
Graphite Electrodes is widely used in metallurgy industry, calculates one ton of steel of every refining need to consume 150kg Graphite Electrodes according to industry, and therefore, Graphite Electrodes belongs to the running stores of metallurgy industry, and consumption is very large.The conventional working method of Graphite Electrodes is that former graphite base is placed in cascade graphitizing furnaces and is formed by large current flow heats.At present, power supply mode is to adopt aluminium mining to be screwed on Graphite Electrodes, then adds D.C. high-current.At the beginning of energising, because electric current is large, the heat of generation is not dispersed in time, causes and on graphite electrode surface, very easily occurs crackle; In addition, the characteristic of expanding with heat and contract with cold due to furnace wall, must on isolation furnace wall, stay an expansion joint every a segment distance, but due to the existence at expansion joint, coke powder in adjacent two furnace chambers exchanges, make the electric current short circuit that leaks electricity in body of heater, cause a large amount of power consumptions, also affected whole production process simultaneously.Therefore, graphitizing furnace is produced the problem that production efficiency is low, power consumption large, Graphite Electrodes product surface quality is low that exists at present.
Summary of the invention
Technical problem to be solved by this invention is that China inkization stove is produced the problem that production efficiency is low, power consumption large, Graphite Electrodes product surface quality is low that exists at present.
[0004]in order to solve the problems of the technologies described above, the invention provides a kind of working method of graphitized electrode, the method adopts the mode that passes into large electric current in adjacent two hearthstone electrode ink serial connections form loop line to process, furnace end electrode power supply adopts transportable transformer car power supply mode, and stove portion adopts movable hydraulic conducting plates short circuit electrode; Between Graphite Electrodes, adopt local non-uniform temperature when just stove resistance adjustment method is eliminated first stove to cause graphite electrode surface seminess; Body of heater divider wall adopts the anticreep divider wall of body of heater to eliminate adjacent two stove leakies.
Further, described first stove resistance adjustment method is: the graphite annulus pad that bonds between described each Graphite Electrodes end, and in this graphite annulus pad, hollow parts is filled insulation carbonaceous material.
Further, described body of heater divider wall is made up of refractory brick, some vertical pores that are equally spaced on the axis of this divider wall, some vertical pores respectively to divider wall both sides unidirectional expansion joint of opening be "
" shape distribution, expansion joint, both sides does not overlap mutually.
Further again, the thickness of described graphite annulus pad is 0.5 ~ 1.5cm.
Further again, described expansion joint is equally spaced.
As a preferred embodiment of the present invention, described divider wall top has a communicating pores to connect all vertical pore, and two openings of this communicating pores are at top, described divider wall two ends.
Beneficial effect of the present invention is:
1, the phase shifting transformer car electric supply installation in technical solution of the present invention, due to every burning-out one stove, only need move to transformer car next stove position, becomes common power supply device, can be the cost that enterprise saves more than 200 ten thousand yuan, has also improved production efficiency simultaneously;
2, the hydraulic pressure electrode device of technical solution of the present invention, has saved the fixing aluminium row's of every stove mounting screw technique, has saved a large amount of fixing aluminium row's time, has improved production efficiency;
3, the first stove resistance adjustment device of technical solution of the present invention has been eliminated graphite electrode surface crackle, has improved the quality of product;
4, the anticreep divider wall of the body of heater of technical solution of the present invention has cut off the path of adjacent two oven coke powder traffic, has cut off leakage current path, has saved a large amount of electric energy, has also improved the quality of product simultaneously.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.

Fig. 2 is the structural representation of the anticreep divider wall of body of heater in technical solution of the present invention.
Embodiment
Fig. 1 is the furnace binding schematic diagram of technical solution of the present invention.As shown in Figure 1, the negative pole of the positive pole of the furnace end electrode 7 of stove I and the body of heater electrode of stove II is moved bus copper coin 8 short circuits of transformer car, in stove I, each Graphite Electrodes 4 is connected in series, the positive pole of the negative pole of the furnace rear electrode 3 of stove I and the furnace rear electrode of stove II is moved hydraulic pressure conductive copper plate 2 short circuits, now, between stove I and stove II, form series connection loop line, phase shifting transformer car is supplied with series connection loop line D.C. high-current through rectifies, and the Graphite Electrodes in body of heater generates heat and greying under the effect of large electric current.
Fig. 2 is the structural representation of the anticreep divider wall of body of heater in technical solution of the present invention.As shown in Figure 2, this divider wall 6 is to be made up of refractory brick, some vertical pores 12 that are equally spaced on the axis of this divider wall 6, some vertical pores 12 be equidistantly to the unidirectional expansion joint of opening 11, divider wall 61 both sides respectively "
" shape distribution, expansion joint, both sides 11 does not overlap mutually.These divider wall 6 tops have a communicating pores to connect all vertical pore 12, and two openings of this communicating pores are at top, described divider wall two ends.On the one hand, the expansion joint 11Hu Bu UNICOM of these divider wall 1 both sides, makes the impossible intercommunication of body of heater both sides coke powder, has cut off the root of electric leakage; On the other hand, ventilating pit 12 makes to be delivered to the heat Quick diffusing on divider wall 6, has reduced the pressure that expands with heat and contract with cold to body of wall, has extended the work-ing life of body of wall.
Technical solution of the present invention is not limited by above-described embodiment, and every technology distortion of doing according to the technology of the present invention principle, within all falling into protection scope of the present invention.
