Description
one, technical field:the invention belongs to aluminum electrolysis industry metallurgical casting technical field, particularly a kind of Bi-metal Steel Aluminum structure anode steel jaw of energy-conserving and environment-protective.
two, background technology:
Aluminum electrolysis industry is power consumption rich and influential family, the height of power consumption is the key factor of restriction aluminium electrolysis enterprise development, so the production management department of electrolytic aluminum is all using reducing power consumption as technological progress in enterprises and improving one of important technology economic target of production management level.As everyone knows, Aluminium Electrolysis power supply system is direct current, low voltage, large current circuit, and what at the current supply circuit of electrolyzer, adopt is low resistance design, to reduce that electrolyzer external voltage falls, is one of energy-conservation effective way of electrolysis of aluminum.We find under study for action, anode steel jaw as one of main conductive component of aluminium cell, its resistance value should be the smaller the better, only in this way could effectively reduce the loss of electric current in conductive process, general aluminium electrolysis anode steel pawl is all that in adopting, carbon cast steel casting forms at present, adopt aluminum steel composite explosion welding sheet transition and aluminium guide bar soldering group to synthesize anode conducting device, mainly play conduction current and carrying anode block weight, take and conduct electricity as main.
The Normal Steel Casting anode steel jaw of existing use is due to the limitation in material, structure and connection technological design, the current loss existing in Aluminium Electrolysis process is larger. and the volts lost of its steel pawl in electrolysis production is generally in 58mV left and right, this present situation for a change, the present invention is through research and experiment for a long time, repeatedly, repeatedly, finally succeeded in developing this Bi-metal Steel Aluminum structure anode steel jaw, according to its volts lost of measuring and calculating, can reduce at least 30mV, every reduction 1mv 3.3 degree that just can economize on electricity, more than ton aluminium just can economize on electricity and reach 90kWh, its energy-saving effect is fairly obvious.
three, summary of the invention:
The object of the invention is for above shortcomings in prior art, and the Bi-metal Steel Aluminum structure anode steel jaw of a kind of energy-conserving and environment-protective of research and design, the Bi-metal Steel Aluminum structure anode steel jaw of these energy-conserving and environment-protective is to obtain on the basis of a large amount of field datas, applying working condition is comprehensively analyzed, and consider the various factors that other affects conductivity, with reference to intrinsic structure, cast steel anode steel jaw has been carried out to reduce internal resistance, the development and design that raising work reliability is target, meeting under the use function of production and the prerequisite of reliability, by reducing the method for anode steel jaw resistance, realized the object of economize on electricity consumption reduction.
Technical scheme is: the Bi-metal Steel Aluminum structure anode steel jaw of energy-conserving and environment-protective of the present invention adopts the replacement of the manufactured materials of antianode steel pawl to realize, the feature of the manufactured materials of anode steel jaw is: (1). adopt oxygen blast technical finesse to reduce C content and the Si content in steel, make C content and Si content in the manufactured materials of anode steel jaw after oxygen blast technical finesse all be down to 0.03-0.10%; (2). by aluminum steel, heat aluminizing technology, in the manufactured materials of the anode steel jaw after front operation is processed, add aluminium, the add-on of aluminium be the anode steel jaw after front operation is processed manufactured materials gross weight 2.5～4.0%, carry out melting; (3). in the manufactured materials of the anode steel jaw after front operation is processed, then add the rare earth silicon of 0.3-0.5% of the manufactured materials gross weight of the anode steel jaw after front operation is processed, melting also mixes, and obtains the manufactured materials of anode steel jaw; (4). punching block casting is used in the manufacture of anode steel jaw, and its surface is extremely cold, easily makes the grain refining on steel pawl surface, thereby has improved electric conductivity, has reduced resistance value.What the manufacture of anode steel jaw adopted at present is evaporative pattern casting, and its shortcoming is that internal defect, electric conductivity reduce, and resistance value is large.Adopt after oxygen blast technical finesse through chemical examination, should make C content and Si content in the manufactured materials of anode steel jaw after oxygen blast technical finesse reach 0.03-0.10%, the meeting of C content and Si content obviously reduces the resistivity of steel, can effectively improve its electric conductivity, oxygen blast technical finesse is prior art, is not stating here more.By aluminum steel, heat aluminizing technology, in the manufactured materials of the anode steel jaw after front operation is processed, add aluminium, the add-on of aluminium be the anode steel jaw after front operation is processed manufactured materials gross weight 2.5～4.0%, carry out melting, because the resistivity of aluminium is 2.83 * 10
-8Ω m, the resistivity of No. 45, No. 35 ordinary steels that use is at present 9.78 * 10
-8Ω m, the resistivity of aluminium is less than 1/3 of steel, so just can effectively improve its electric conductivity, reduction resistance value, and then reduce volts lost, has also improved the erosion resistance of the manufactured materials of anode steel jaw simultaneously.In the manufactured materials of the anode steel jaw after front operation is processed, add again the anode steel jaw after front operation is processed manufactured materials gross weight 0.3-0.5% rare earth silicon melting and mix, its effect is abundant crystal grain thinning, improved electric conductivity, reduced resistance value, and then reduction volts lost, improved equally again the erosion resistance of the manufactured materials of anode steel jaw.
The present invention is after above a series of processing, the manufactured materials of new anode steel jaw was compared with former Normal Steel Casting, at aspect of performance, obtained very large change, advantage be mainly manifested in improve high temperature resistant, corrosion resistant performance, resistivity reduces greatly, conductivity improves greatly, according to repeated multiple times measuring and calculating, in existing Aluminum Electrolysis Production, the volts lost of steel pawl is generally in 58mV left and right, in Aluminum Electrolysis Production of the present invention, the volts lost of steel pawl is generally in 28mV left and right, its volts lost can reduce at least 30mV, its reduction amplitude reaches more than 50%, according to calculating every reduction 1mv 3.3 degree that just can economize on electricity, more than ton aluminium just can economize on electricity and reach 90kWh, to produce the medium-sized manufacturing enterprise of 300,000 tons of aluminium per year, calculate, year economize on electricity reaches 2,700 ten thousand degree, its energy-saving effect is fairly obvious, economic benefit is very remarkable, competitive capacity and the viability of enterprise have greatly been improved, its environment protecting is also fairly obvious, economic benefit and social benefit are very remarkable.
Say objectively, it also can bring a bit not enough, and its shortcoming is in steel, add aluminium and reduce after C, Si content, and the intensity of its steel pawl (hardness) can slightly reduce, but can not affect the normal production of electrolysis.The replacement of the manufactured materials of the Bi-metal Steel Aluminum structure anode steel jaw employing antianode steel pawl of energy-conserving and environment-protective of the present invention and casting improve and realize, and the shape of existing anode steel jaw and structure are not improved, therefore its view is omitted.
