Abstract
The process of dipping graphite onto anode steel pawl for aluminum electrolysis features that the anode steel pawl is inserted vertically into graphite powder to make the four pawl ends coated with graphite powder. The process without kerosene added into graphite makes the subsequent anode casting process no burning of kerosene, environment friendly and simple.
Description
Technical field
A kind of method of dipping graphite onto anode steel pawl relates to the method for the dipping graphite onto anode steel pawl in a kind of aluminium electrolysis process.
Background technology
In aluminium electrolysis process, each cycle all will carry out dipping in the operation of covering graphite on anode steel jaw.It is with kerosene fusion Graphite Powder 99 that traditional anode steel jaw dips in graphite method, anode steel jaw is immersed in the mixture of kerosene and Graphite Powder 99, carries out promptly that graphite is wet to dip in operation.Overlay on dipping in of anode steel jaw and contain kerosene in the coating owing to dip in, during anode casting, the kerosene burning can be produced flare a large amount of black smokes of emerging, operating environment is worsened, cause environmental pollution problems, the wet graphite that dips in each cycle is operated, carry out sand washing steel pawl, dip in and cover the process operation complexity.
Summary of the invention
The objective of the invention is the deficiency that exists at above-mentioned prior art, provide a kind of can effectively solve on anode steel jaw, to dip in cover graphite and produce the operating environment deterioration problem, and the method for the simple dipping graphite onto anode steel pawl of operating process.
The objective of the invention is to be achieved through the following technical solutions.
A kind of method of dipping graphite onto anode steel pawl, it dips in the process of covering is that anode claw is vertically inserted in the Graphite Powder 99, four pawl heads is dipped in be covered with Graphite Powder 99; It is characterized in that dipping in that to cover Graphite Powder 99 be that density is 1.2～1.35g/cm
3, carbon weight percentage greater than 98.5%, the percentage composition of moisture content less than 0.5%, ash and fugitive constituent less than 1%, granularity is the Graphite Powder 99 less than 0.05mm.
Adopt method of the present invention,, do not adopt kerosene fusion Graphite Powder 99 owing to dip in the process of covering Graphite Powder 99, when having eliminated anode casting, the kerosene burning can be produced flare a large amount of black smokes of emerging, and has solved the operating environment deterioration, cause environmental pollution problems, operating process is simple, and is effective.
Embodiment
A kind of method of dipping graphite onto anode steel pawl, it dips in the process of covering is that anode claw is vertically inserted in the Graphite Powder 99, four pawl heads is dipped in be covered with Graphite Powder 99; Dip in that to cover Graphite Powder 99 be that density is 1.2～1.35g/cm
3, carbon weight percentage greater than 98.5%, the percentage composition of moisture content less than 0.5%, ash and fugitive constituent less than 1%, granularity is the Graphite Powder 99 less than 0.05mm.
Embodiment 1
With density is 1.2g/cm
3, carbon content is 98.5%, moisture content is 0.5%, ash and fugitive constituent are 1%, granularity is put into graphite boxes and shakeout for-the Graphite Powder 99 of 0.05mm, highly be 10cm, the anode joint surface phosphorus pig iron and face-piece are cleaned out, slowly vertically put into graphite boxes with overhead traveling crane handling steel pawl group, make four pawl heads evenly dip in Graphite Powder 99, requiring to dip highly is 10cm.The big and over-emitting black exhaust of kerosene burning flare makes the operating environment variation when having eliminated anode casting, causes the certain environment pollution problems.
Because the dried graphite method effect of dipping in is better, can dip in once every one-period, anode steel jaw is sand washing no longer, and pressure drop of aluminium charcoal and former technology remain basically stable.
Embodiment 2
With density is 1.35g/cm
3, the carbon weight content is 98.8%, moisture content 0.49%, ash and fugitive constituent are 0.8%, granularity is put into graphite boxes and shakeout for-the Graphite Powder 99 of 0.05mm, highly be not less than 10cm, the anode joint surface phosphorus pig iron and face-piece are cleaned out, slowly vertically put into graphite boxes with overhead traveling crane handling steel pawl group, make four pawl heads evenly dip in Graphite Powder 99, requiring to dip highly is 12cm.The big and over-emitting black exhaust of kerosene burning flare makes the operating environment variation when having eliminated anode casting, causes the certain environment pollution problems.Because the dried graphite new technology effect of dipping in is better, dips in once every one-period, pressure drop of aluminium charcoal and former technology remain basically stable.
