Technical field
The invention belongs to aluminium cell technical fields, and in particular to a kind of aluminium electrolysis cathode carbon block phosphorus pig iron casting unit and
Casting method.
Background technique
Cathode carbon pieces assembling is the technical process that cathode carbon pieces and cathode steel bar are closely linked.Cathode carbon pieces
There are mainly three types of methods for assembling: it is the gap that filling rod iron two sides are pasted with charcoal that charcoal paste, which makes construction from part firm by ramming, then will with pneumatic tools
It makes compacting firm by ramming；Phosphorus pig iron casting method is the gap using the phosphorus pig iron casting of thawing between them, makes one after condensation
The method of body；Mull technique is the method that cathode carbon pieces and rod iron are bonded together with adhesive or charcoal glue.It is domestic at present universal
Construction from part is fiddled with using charcoal paste, mull technique uses less.However phosphorus pig iron casting method is because of spies such as its secured, electrical efficiency height of assembling
Point is greatly paid close attention to.But this method finds problem easy to crack, qualification rate is low of casting after test of many times, it is difficult to practical
It promotes.For the assembling of the phosphorus pig iron, 1320 DEG C are up in the temperature of casting process medium phosphoric iron, and the temperature of carbon block and rod iron
Spend it is relatively low so that cracking phenomena can occur for carbon block, to influence the normal use of carbon block.And the cracking of carbon block, it increases
The production cost of electrolytic aluminium, while also reducing the service life of electrolytic cell.Therefore, this technical problem how is solved, is phosphorus
The key that pig iron casting method promotes and applies.
Summary of the invention

Position, one is cooling station；
Step 2: when the heating temperature of certain heating station reaches requirement, phosphorus pig iron casting unit receives instruction, then drives
Dynamic locomotive proceeds to the heating station；Hoisting mechanism declines four suspension centres for catching on heating mantles, and heating mantles are lifted beyond
Cathode carbon pieces upper surface；The heating station becomes station to be cast at this time；
Step 3: heating mantles are transported to assembling station by phosphorus pig iron casting unit, are put down heating mantles and are covered assembled cathode
Carbon block and cathode steel bar, heating mantles start to heat it；The assembling station becomes the station of heating at this time；
Step 4: phosphorus pig iron casting unit is gone at coreless induction furnace, is added phosphorus pig iron molten iron in packet system toward pouring, is then return to step
Being cast in rapid 2 by the station to be cast that heating station becomes；Casting process: hoisting mechanism drives cast gate separate system
Decline, pour afterwards in place packet system internally translate then rotate start to cast；Molten iron is four by one point, and four points are 16, casting
It completes；Cooling station should be become by the station to be cast that heating station becomes again at this time；
Step 5: on the contrary then continue in repetition if phosphorus pig iron casting unit there are also the waiting time, returns to waiting station
Movement is stated, the period carries out.
Compared with the prior art, the beneficial effects of the present invention are full hydraulic system is used, power cost is reduced, is made simultaneously
The ordinary start and stop for obtaining locomotive are more steady, prolong the service life.Beneficial effects of the present invention are also resided in be driven by a pair of of oil cylinder,
Realize heating mantles, cast gate separate system, finished product carbon cathode blocks elevating control.Beneficial effects of the present invention, which also reside in, utilizes 6+1
Station form, realize the automatic casting of beat-type.

Specific embodiment
The present invention is described in further detail with reference to the accompanying drawings and examples.
As Figure 1-Figure 4, phosphorus pig iron casting unit of the invention composition is by locomotive 1, pours packet system 2, door frame system
System 3, hoisting mechanism 4, cast gate separate system 5, control cabinet 6, heating mantles 7, hydraulic station 8, track 9, cathode steel bar 10, cathode carbon pieces
11, the components such as workbench 12 form.
The institute of whole system is dynamic all to be provided by hydraulic station 8.Four pieces of cathode carbon pieces 11 are placed in one heating mantles 7,
One piece of cathode carbon pieces 11 needs four cathode steel bars 10 to assemble, the corresponding cast gate of every cathode steel bar 10.
Cast gate separate system 5 has four groups, and every group there are four cast gates, just corresponding with cathode steel bar 10.Cast gate separate system 5
It can be realized lifting by the driving of lifting device 4.
Pouring packet system 2 has the function of moving horizontally and rotate and topple over, while there are four diffluence pass, pass through the appearance of four chambers
The equal flow to guarantee four diffluence pass of product.
Hoisting mechanism 4 be responsible for all vertical-lift campaigns by a group oil cylinder, including heating mantles 7, cast gate separate system 5,
Finished product carbon cathode blocks (i.e. cathode carbon pieces 11 and cathode steel bar 10 assemble the product after casting is integrated).
The present invention is implemented:
As shown in Figure 1, station one is phosphorus pig iron casting unit waiting station；Two-station of station seven is construction station, wherein
Three are heating station, and one is assembling station, and one is casting station, and one is cooling station.For the ease of statement, it is assumed that
This period station two, station three, station four are heating station, and station five is assembling station, and station six is casting station, station
Seven be cooling station.Phosphorus pig iron casting unit is after station six has been cast, if returning to waiting station there are also the waiting time
One.Station five has manually been completed at the same time, is waited to be heated.
Firstly, phosphorus pig iron casting unit receives instruction when two heating temperature of station reaches requirement, then locomotive is driven
1 proceeds to station two, as shown in Figure 1.Hoisting mechanism 4 declines four suspension centres for catching on heating mantles 7, and heating mantles 7 are promoted and are surpassed
Cross 11 upper surface of cathode carbon pieces.Station two becomes station to be cast at this time.
Secondly, heating mantles 7 are transported to station five by phosphorus pig iron casting unit, put down heating mantles 7 and cover assembled cathode
Carbon block 11 and cathode steel bar 10, heating mantles 7 start to heat it.Station five becomes the station of heating at this time.
Finally, phosphorus pig iron casting unit is gone at coreless induction furnace (being not drawn into figure), phosphorus pig iron iron is added in packet system 2 toward pouring
Water is then return to station two and casts.Casting process: hoisting mechanism 4 drives cast gate separate system 5 to decline, in place rear casting ladle
System 2 internally translates then rotation and starts to cast.Molten iron is four by one point, and four points are 16, and casting is completed.Station two at this time
Become cooling station again.On the contrary it is then continue again if phosphorus pig iron casting unit there are also the waiting time, returns to waiting station one
Multiple above-mentioned movement, period carry out.
Certainly, above is specific application example of the invention, and there are other embodiments of the invention, all using equivalent
The technical solution that replacement or equivalent transformation are formed, all falls within protection scope of the presently claimed invention.
