Description
Technical field
This utility model relates to a kind of aluminium electrolysis anode, particularly a kind of Prebaked Anode In Aluminium Cell group structure.
Background technology
Modern Aluminium Industry, all uses prebaked anode to produce electrolytic aluminium.Prebaked anode is generally cuboid, has stable geometry, with stone tar, pitch coke as aggregate, with coal tar pitch as binding agent, has different sizes according to the size of electrolytic cell currents and the difference of technique, and its electric current density is typically at 0.68-0.9A/cm2In the range of, each carbon block uses the cycle typically at 23-30 days.
In existing prebaked anode Aluminum Electrolysis Production, anode steel claw all uses phosphorus pig iron casting formula to be connected with anode carbon block, upper surface at pre-baked anode carbon blocks conducting direction is provided with 2-4 a diameter of 160-180mm, it is the circular groove of 80-110mm deeply, it is commonly called as charcoal bowl, when anode assembling, charcoal bowl is used for laying anode joint, with the phosphorus pig iron, anode joint is cast in charcoal bowl, steel pawl head and aluminum conducting rod are connected by aluminum steel blast weldering, so conductive anode rod and anode carbon block is connected as a single entity, composition anode carbon block group, casting type pre-baked anode carbon blocks group is unique anode material that modern prebaked cell is currently used.
During Aluminum Electrolysis Production, the oxygen that carbon anode and alumina eltrolysis decompose out the most constantly reacts, carbon dioxide gas and constantly consume, need timing to change, referred to as anode anode scrap in the carbon block industry changed.Prd-baked Al electrolysis produces and must produce a large amount of anode anode scrap, and it is last century 60～the seventies that non-residual electrode produces, and prd-baked Al electrolysis technical maturity carrys out the industry dream never realized.
Now the current processing mode to traditional anode anode scrap is in anode assembling workshop, the anode scrap that conducting rod connects is smashed after coming off, the anode steel bowl poured by the phosphorus pig iron again is smashed the aluminum conducting rod after coming off and is used for new carbon block, so recycling, the Renewal process having thereby resulted in carbon block is wasted time and energy.
And the 10-15% that generation amount is aluminium ingot yield of generally anode anode scrap, thereby produce waste greatly, produce ten thousand tons of electrolytic aluminiums of 2600-2700 per year by present China to calculate, anode anode scrap is up to 260-390 ten thousand tons/year, the anode carbon block wasted every year according to 2700 yuan/ton of value calculation of anode carbon block is worth and reaches 10,000,000,000 yuan, global waste is more, anode anode scrap soaks for a long time in the fused electrolyte of electrolysis bath, and anode carbon element itself has the porosity of 25-27%, substantial amounts of electrolyte has been adsorbed in anode scrap body, the main component of electrolyte is fluoride salt, anode anode scrap containing a large amount of fluoride salts is extremely serious to the pollution of environment.
Casting type steel pawl carbon block connected mode, joint face contact drop is bigger, the phosphorus pig iron molten iron temperature poured into about 1600 DEG C, after cooling, gap must occur, thus, when steel pawl carbon block anode unit works in electrolysis bath between phosphorus pig iron bowl and charcoal bowl, produce the voltage drop of about 150mv between steel pawl and carbon block contact surface, cause electricity to damage about at 400～500 KWhs/ton of aluminum.
When using existing casting type anode carbon block group, in order to reduce as far as possible anode scrap waste must try one's best anode scrap is burnt thin, at anode carbon block end of lifetime, the end face of anode carbon block is sufficiently close to electrolyte level face, by magnetic field and airflow influence, bath surface constantly has strong wave to produce, or because producing control deviation, in actual production process, anode steel claw is often by electrolyte etch, the ferrum of steel pawl dissolves in electrolyte, enter aluminum water immediately and affect aluminium ingot quality, in actual production, the steel pawl average life that potroom uses only has about 3 years, this also makes production cost have certain increase.And at anode carbon block end of lifetime, the thinnest anode scrap thickness, necessarily bring charcoal pole conduction inequality, cause electrolysis bath fluctuation of operating conditions, electricity damages to be increased.
