Abstract
The invention provides a method for dipping an anode yoke of an anode guide rod assembly into graphite and further provides a graphite dipping device. The method includes adding 100kg of graphite powder into a graphite cuvette, and scrabbling the graphite powder back and forth by a dregs rake to ensure the height of the graphite powder in the graphite cuvette to be 130mm; dragging the guide rod assembly to move above a graphite machine by a suspension chain, and inserting the anode yoke into the graphite cuvette to dip the graphite; after the anode yoke dips the graphite, re-dragging the guide rod assembly by the suspension chain to move and pass through a brush above the graphite cuvette, and evenly smearing the graphite powder attached to the anode yoke by the brush until no visible small graphite blocks remain on the surface of the anode yoke. The adhesion height of the anode yoke is 100-120mm. Compared with the related technology, the method has the advantages that escape performance of iron hoops after casting is good, casting cost and pollution are reduced, and casting quality and efficiency are improved.
Description
[technical field]
The present invention relates to anode technology field, relate in particular to a kind of method that anode guide rod steel claw dips in graphite.
[background technology]
Assembling is to use molten iron to pour into a mould in carbon bowl to form iron hoop, together with the guide rod steel claw of cleaning out is made with charcoal block casting, is last procedure in anode production flow process.After anode uses on electrolytic cell, remaining anode scrap is sent back to composing room the iron hoop on steel pawl is carried out to pressure-off, reclaims guide rod steel claw, iron hoop recycling.For prevent steel pawl and molten iron too bond anode scrap when cleaning iron hoop cannot pressure-off out, will be at the steel pawl head powder of graphiting as the inherent steel pawl of industry, anode casting are last.
The technique of current a kind of steel pawl head graphitization powder: graphite powder is put into kerosene or diesel oil furnishing pasty state, with brush, brush on steel pawl head again, also can directly steel pawl head be put in graphite paste and dip in, in this technique, graphite accounts for ratio that graphite sticks with paste and is generally 25%～40% and just can meets production requirement, in production process mainly there is following problem in this technique: graphite dips in attached inhomogeneous on steel pawl head, during to assembling casting, because steel pawl is subject to washing away of molten iron, part graphite will float over phosphorus molten pig iron surface, even in the middle of the phosphorus pig iron, solidify and increase phosphorus pig iron self-resistance, weaken phosphorus pig iron intensity, this technological design person considers that molten iron can wash away this problem of steel pawl head graphite, and during graphite is stuck with paste, the allocation ratio of graphite is increased to 25%～40% to meet Production requirement, has wasted about 30% graphite in the middle of invisible.
The technique that also has at present a kind of steel pawl head graphitization powder is to adopt air atomization spray gun that the mixture of kerosene and graphite is sprayed on steel pawl head, and can be by particle atomization between 80～100 μ m, therefore the consumption of kerosene and graphite significantly reduces, in production process mainly there is following problem in this technique: be sprayed at that graphite on steel pawl is inhomogeneous causes the pressure-off of the phosphorus pig iron poor, on steel pawl, be with iron quantity to account for 40%, the production efficiency of impact assembling; Casting cycle, because graphite powder can not be dried in time, produces gas during casting, the molten iron bulge that causes casting, impact casting quality and efficiency.
Therefore, the method that anode guide rod steel claw dips in graphite at present, still haves much room for improvement.
[summary of the invention]
The technical problem that the present invention need solve is, a kind of method that provides anode guide rod steel claw that can reduce casting cost, good, the effective raising casting efficiency of phosphorus pig iron pressure-off and casting quality to dip in graphite.
The method that a kind of anode guide rod steel claw of the present invention dips in graphite, a kind of graphite device that dips in is provided, the described graphite device that dips in comprises graphite machine, slag rake, hairbrush, stretched wire, guide rod, described graphite machine comprises graphite cuvette, described hairbrush is suspended at described graphite cuvette top, described guide rod is provided with steel pawl, said method comprising the steps of:
Get graphite powder 100kg and add in described graphite cuvette, with described slag rake, take off back and forth, guarantee that the graphite powder height in described graphite cuvette is 130mm;
Described guide rod is dragged and is moved to described graphite machine top by described stretched wire, and described steel pawl is inserted in described graphite cuvette and dips in graphite;
Described steel pawl has dipped in after graphite, and described guide rod drags operation by described stretched wire again, from the described hairbrush of described graphite cuvette top, passes through, and described hairbrush is smeared evenly dipping in attached graphite powder on described steel pawl, until described steel pawl surface is without visible graphite fritter;
Wherein, the attached height that dips in of described steel pawl is 100-120mm.
Compare with correlation technique, beneficial effect of the present invention is, after casting, the pressure-off of the phosphorus pig iron is good; Do not increase the proportional quantity of graphite, do not use kerosene, reduce casting cost, reduce the generation of a large amount of flue gases, reduce and pollute; After casting, the phosphorus pig iron, without bubble bulge phenomenon, improves casting efficiency and quality; Reduce the iron charcoal pressure drop 5-6 millivolt of anode group.
[specific embodiment]
Describe embodiments of the invention below in detail.The embodiment the following describes is exemplary, only for explaining the present invention, and can not be interpreted as limitation of the present invention.
The present invention proposes a kind of method that anode guide rod steel claw dips in graphite, a kind of graphite device that dips in is provided, the described graphite device that dips in comprises graphite machine, slag rake, hairbrush, stretched wire, guide rod, described graphite machine comprises graphite cuvette, described hairbrush is suspended at described graphite cuvette top, described guide rod is provided with steel pawl, said method comprising the steps of:
Get graphite powder 100kg and add in described graphite cuvette, with described slag rake, take off back and forth, guarantee that the graphite powder height in described graphite cuvette is 130mm;
Described guide rod is dragged and is moved to described graphite machine top by described stretched wire, and described steel pawl is inserted in described graphite cuvette and dips in graphite;
Described steel pawl has dipped in after graphite, and described guide rod drags operation by described stretched wire again, from the described hairbrush of described graphite cuvette top, passes through, and described hairbrush is smeared evenly dipping in attached graphite powder on described steel pawl, until described steel pawl surface is without visible graphite fritter;
Wherein, the attached height that dips in of described steel pawl is 100-120mm.
The present inventor's discovery, traditional anode rod dips in the method for graphite, and the increase of graphite allocation ratio has improved casting cost, and graphite is inhomogeneous causes the pressure-off of the phosphorus pig iron poor, produces the problems such as gases affect casting efficiency and quality during casting.Therefore, there is no in fact at present the method that the anode guide rod steel claw that can effectively solve the problems of the technologies described above dips in graphite.The present inventor is surprised to find, and by method of the present invention, can successfully solve the example existing in prior art technical problem described above.
