Abstract
The utility model discloses a trimetal anode explosion piece for an aluminum electrolytic cell, which comprises an aluminum plate (1) and a steel plate (4); a titanium plate (2) is arranged between the aluminum plate (1) and the steel plate (4); the aluminum plate (1), the titanium plate (2) and the steel plate (4) are connected into a whole body by explosion welding; a layer of aluminum-titanium explosion composite surface (3) is formed between the bottom of the aluminum plate (1) and the upper part of the titanium plate (2); and a layer of titanium steel explosion composite surface (5) is formed between the bottom of the titanium plate (2) and the upper part of the steel plate (4). The titanium plate is additionally arranged between the aluminum plate and the steel plate, so the utility model improves the performance of an anode explosion composite block; and compared with the prior anode explosion composite block, the tensile strength of the anode explosion composite block is improved by 3 to 3.5 times, the shearing resistant strength is improved by 2.0 to 2.5 times, the base value is higher, the influence of the temperature is greatly reduced and the high-temperature performance is more stable.
Description
Technical field
The utility model relates to a kind of anode composite block, especially aluminium cell three metal anodes blast sheet.
Background technology
In aluminium cell, anode is made up of three parts such as anode carbon block, anode steel jaw, aluminium guide bars.At first, by the anode rod assembly that is welded, then, the steel pawl of anode carbon block and anode rod assembly is assembled into anode by the casting phosphorus pig iron again with anode steel jaw and aluminium guide bar.The anode blast composite block of using now is-bimetal copper-steel anode blast composite block, adopts aluminium sheet and steel plate to be composited by the blast mode.Aluminium-bimetal copper-steel anode blast composite block tensile strength at normal temperatures is about 100Mpa, and shear strength is about 60Mpa, and working temperature is not higher than 400 ℃; And, the tensile strength and the shear strength of aluminium-steel blast composite surface rise and significantly descend along with working temperature, it is special after working temperature is higher than 300 ℃, its tensile strength and shear strength descend rapidly, when 350 ℃ of working temperatures, when only being normal temperature about 3/4 of tensile strength and shear strength; When 400 ℃ of working temperatures, when only being normal temperature about 1/2 of tensile strength and shear strength.When aluminium cell is gone into operation the initial stage, electrolyzer temperature is high unusually, anode is prone to bias current, can cause indivedual anode steel jaws rubescent, aluminium-steel blast composite surface temperature is near 400 ℃, make the tensile strength of aluminium-steel blast composite surface and shear strength only be respectively about 50Mpa with 30Mpa about, add electrolytical molecular ratio height of operation initial stage, the electrolyte shell surface of formation is very hard, intensity is high especially.Therefore, during anode change, can cause indivedual anodes to come off from aluminium-steel blast composite surface drawing crack.The anode drawing crack comes off and not only damages the anode rod assembly, and the more important thing is influences the electrolyzer stably manufactured.
The utility model content:
The purpose of this utility model is: a kind of aluminium cell three metal anodes blast sheet is provided, and its tensile strength and shear strength height, the performance variation of temperature influence is little, and high-temperature behavior is more stable, to overcome the deficiencies in the prior art.
The utility model is achieved in that aluminium cell three metal anodes blast sheet, it comprises aluminium sheet, steel plate, be provided with a titanium sheet between aluminium sheet and the steel plate, adopt explosive welding to connect as one between aluminium sheet, titanium sheet and the steel plate, constitute layer of aluminum-titanium blast composite surface between aluminium sheet bottom and the titanium sheet top, constitute one deck titanium-steel blast composite surface between titanium sheet bottom and the steel plate top.
Wherein, the thickness of aluminium sheet is 10～30mm, and the thickness of titanium sheet is 1～5mm, and the thickness of steel plate is 30～50mm.
Owing to adopted technique scheme, compared with prior art, the utility model is passing through to increase a titanium sheet between aluminium sheet and steel plate, to improve the performance of anode blast composite block, it is compared with original anode blast composite block, and its tensile strength is high 3～3.5 times; Its shear strength is high 2.0～2.5 times; Not only basic value is higher, and temperature influence reduces greatly, and high-temperature behavior is more stable.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is a use synoptic diagram of the present utility model.
Embodiment
In use, at first with the boss welding of steel plate 4 with anode steel jaw 6; And then with aluminium sheet 1 welding.In two welding processes, should be specifically noted that to guarantee that aluminium guide bar 7 and titanium sheet 2 both sides blast composite surface temperature are lower than 425 ℃, require every weld seam to divide 4～5 roads (layer) to finish.When working temperature is 350 ℃, about 85% when its tensile strength and shear strength value are normal temperature (185Mpa and 85Mpa); When 400 ℃ of working temperatures, when only being normal temperature about 60% of tensile strength and shear strength (130Mpa and 60Mpa); Three metal anodes blast composite block is compared with aluminum steel bimetal anode blast composite block when working temperature is 350～400 ℃, and its tensile strength is high 3～3.5 times; Its shear strength is high 2.0～2.5 times; Not only basic value is higher, and temperature influence reduces greatly, and high-temperature behavior is more stable.
