Description
Technical field
The present invention relates to a kind of anode carbon block group structure, more particularly to a kind of energy-conservation, the aluminum electrolyzing cell used anode of easy care
Carbon block group.
Background technology
Metallic aluminium is industrially produced using fused salt electrolysis process, i.e. electrodissolution is main component in molten cryolitic
Electrolyte in aluminum oxide, the method mainly used at present is Hall-Ai Lu（Hall-Heroult）Electrolysis.
The direct equipment for producing electrolytic aluminium is electrolytic cell, and electrolytic cell is mainly made up of two large divisions, and a part is anode, separately
One is negative electrode, and anode carbon block group participates in the normal reaction of electrolytic cell, anode carbon block is in electrolytic process as the positive pole of electrolytic cell
In constantly consume, after certain time, anode scrap is changed, and is assembled new anode carbon block after being handled in anode assembling workshop, is returned to electricity
Workshop is solved to recycle.
Generally, anode electrolytic cell carbon block group structure is made up of anode carbon block, aluminum guide, blast welding block, steel pawl and the phosphorus pig iron,
Anode carbon block group assemble when, first by aluminum guide, blast welding block and steel pawl weld together composition guide rod group, then by guide rod group with sun
Pole carbon block group pair, the steel pawl of guide rod group is inserted into the charcoal of anode carbon block bowl, and the phosphorus pig iron for melting of casting, the phosphorus pig iron after cooling
Guide rod group and anode carbon block are linked together, anode carbon block group is constituted.Electric current passes sequentially through anode rod, blast welding block, steel
Pawl, ferrophosphorus and anode block, therefore, steel pawl are not only the weight for undertaking anode block, are also electric conductor.
Usual steel pawl is formed using evaporative pattern cast, and the evaporative pattern that will have been manufactured by steel pawl size is put into sandbox, will be molten
Melt under state in molten steel injection sandbox, evaporative pattern melts, and molten steel substitutes the space of original evaporative pattern, forms steel pawl.This structure
Steel pawl, influenceed by pouring technology, the design of such as mould, the temperature of molten steel, the mobility of molten steel in a mold, exhaust is set
Meter etc., it will usually cause stomata, trachoma, the defect of apparent mass difference, cause resistivity to raise, the voltage drop of anode steel claw increases
Plus.Further, since steel pawl should generally carry carbon block weight, while be electric conductor again, because the resistivity of steel is larger, therefore,
Also the voltage drop of steel pawl is increased.
The content of the invention
A kind of aluminum electrolyzing cell used anode carbon block group is provided to solve the above-mentioned technical problem present invention, purpose is solved because steel pawl is poured
The inside caused and visual defects are noted, steel pawl crossbeam is mainly bonding strength, it is ensured that anode is not fallen off, while having the work(of conduction concurrently
Can, attachment structure is responsible for conduction, anode unit pressure drop can be greatly lowered, is significantly reduced from the small material of resistivity ratio steel
Ton aluminium energy consumption.
To achieve these goals, the present invention is realized in：A kind of aluminum electrolyzing cell used anode carbon block group, including aluminium are led
Bar, conductive steel column and anode carbon block, aluminum guide are connected by gooseneck with conductive steel column, and the bottom of conductive steel column is inserted into anode carbon
In block, gooseneck is made up of the aluminium sheet on upper strata and the steel plate of lower floor, and aluminum guide welds or used connection sheet with gooseneck upper strata aluminium sheet
Connection, gooseneck lower floor steel plate and conductive steel column steel-steel welding or founding.
Described aluminum guide is connected with gooseneck crown center position, conductive steel column and gooseneck bottom steel plate weld or molten
Casting, the one end of the two ends of gooseneck upper strata aluminium sheet respectively with two connection sheets is connected, the other end and aluminum guide of two connection sheets
Connection.
The aluminium sheet of gooseneck can be a monoblock or the small aluminium sheet composition of polylith.
The aluminium sheet gross thickness of gooseneck is 10~100mm.
The cross section of the steel plate of gooseneck is square, circular or ellipse.
Connection sheet is band, plate or bus.
Gooseneck and conductive steel column are integrated.
Connection sheet is aluminium or copper.
Advantages of the present invention and effect：The present invention has very strong practicality, and one is the aluminum steel for eliminating conventional anode group
Explode welding block, and two be that steel pawl conduction replaces part steel pawl using connection sheet, reduces steel pawl pressure drop.
