Description
Technical field
The present invention relates to electric locomotive technical field, particularly relate to the preparation method of a kind of pantograph carbon draw runner.
Background technology
Development along with railway, bullet train is also going from strength to strength, wherein, the bullet train of electric propulsion be by pantograph carbon slide system incessantly with contact line conducting wire CONTACT WITH FRICTION, electric current on electrical network is guided, is transferred to locomotive electrical system to maintain electric locomotive properly functioning.Therefore, pantograph pan is the important collecting element that electric locomotive obtains power, pantograph carbon slide is a kind of contact material integrating high conductivity, wear resistence and antifriction performance, should there be good electric conductivity and collection power, matching with bow net coupled system again, the pantograph pan being therefore fabricated to by this material constitutes a pair machinery and the special friction of electrical couplings with the relation of contact line conducting wire.
Owing to pantograph carbon slide is chronically exposed in natural environment, often work under dry the humidity even vile weather such as sand and dust and sleet, and, during high-speed cruising, carbon slipper and contact line conducting wire constantly produce surge and wear away with mechanical shock, thus become and electric locomotive is changed most frequent, that consumption is maximum parts.Therefore selecting the pantograph carbon slide with excellent comprehensive performance to become inevitable, the condition possessed needed for it is: good electric conductivity；Excellent abrasion resistance and self lubricity；Mechanical strength is high, is amenable to necessarily vibrate with shock loading and does not damages；Hardness number is less than the hardness of contact wire；Lightweight.And the quality of the carbon bar on slide plate is to affect a key factor by current quality.Carbon bar itself should have certain mechanical strength, the performance of Wear-resistant to be had.
But, existing carbon draw runner preparation method is usually pitch coke and Colophonium kneading at a certain temperature, squeeze out products formed and carry out a roasting, carry out impregnating pitch again, carry out after baking the most again, carbon draw runner that this preparation method produces exists such as wastes time and energy, increase cost, production efficiency is low, and the carbon draw runner toughness difference that manufactures and the more high defects of rupture strength.
Therefore it is necessary to set about from key point, design the preparation method of a kind of pantograph carbon draw runner, manufacture out the high performance pantograph carbon draw runner meeting bullet train, to solve the technical problem of above-mentioned poor performance.
Summary of the invention
For problem present in background technology, it is an object of the present invention to provide the preparation method of a kind of pantograph carbon draw runner, manufacture out high performance pantograph carbon draw runner, production operation is simple, time-consuming, improves efficiency, reduces cost, increases economic efficiency.
The technical scheme is that and be achieved in that: the preparation method of a kind of pantograph carbon draw runner, comprise the following steps: S1, petroleum coke, pitch coke and modified coal tar pitch are pulverized；S2, petroleum coke powder, Colophonium coke powder and modified coal tar pitch powder by ground carry out kneading and become thickener；The thickener that S3, kneading are good carries out rolling sheet after taking the dish out of the pot on flaking machine；S4, carry out pulverizing to rolling sheet；S5, the powder of milled is entered press carry out compacting of heating；S6, the products formed suppressed carry out roasting；S7, until furnace temperature reduce after come out of the stove, pantograph carbon draw runner molding.
In technique scheme, in described step S1, the content of petroleum coke is 95%, and the content of pitch coke is 5%, and the content of modified coal tar pitch is 30%.
In technique scheme, in described step S1, the particle diameter after petroleum coke, pitch coke and modified coal tar pitch being pulverized is 825 mesh.
In technique scheme, in described step S2, the kneading time is 1.5 hours, and kneading temperature is 200～210 DEG C.
In technique scheme, in described step S3, it is 170～180 DEG C that thickener goes out pot temperature.
In technique scheme, in described step S4, it is 625 mesh to rolling the particle diameter after sheet carries out pulverizing.
In technique scheme, in described step S5, pulverizing enter press carry out heating compacting time, pressure is 15MPa.
In technique scheme, in described step S6, the temperature of roasting is 900 DEG C, and roasting time is 360 hours.
In technique scheme, in described step S7, come out of the stove when furnace temperature is reduced to ＜ 200 DEG C.
In technique scheme, in described step S7, the indices of the pantograph carbon draw runner after molding of coming out of the stove is: bulk density is 1.70～1.74g/cm3；Shore hardness is 68～95HS；Resistivity is 34～37.5 μ Ω m；Rupture strength is 35～62MPa；Comprcssive strength is 72～96MPa；Toughness is 0.13～0.18J/cm2。。
The preparation method of the present invention a kind of pantograph carbon draw runner, thickener is become by carrying out kneading after petroleum coke, pitch coke and modified coal tar pitch being pulverized, again the thickener that kneading is good is taken the dish out of the pot and carry out pulverizing to rolling sheet after carrying out rolling sheet on flaking machine, then the powder of milled is entered press carry out heating compressing after carry out roasting, finally come out of the stove after furnace temperature reduces, pantograph carbon draw runner molding.Thus prepared method can produce high performance pantograph carbon draw runner, and material purchases are easy, save dipping process, reach production operation simple, time-consuming, improves efficiency, reduces cost, the beneficial effect increased economic efficiency.
Accompanying drawing explanation
Fig. 1 is the preparation method flow chart of the present invention a kind of pantograph carbon draw runner.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of protection of the invention.
