Aluminium block in aluminium bar and steel-aluminium composite block is welded to connect by weld seam I aluminium-aluminium, because aluminium-aluminium weld seam is not only born electric action aborning, also wanted load capacity, therefore requires higher to its intensity and conductive capability.And compared with the joint of aluminium-aluminium weld seam and mother metal or steel-aluminium composite block, intensity is much lower, only can reach 85% of strength of parent lower limit, effectively connection area is less in addition, and therefore weld seam intensity or conductive capability all become the weakest part of whole anode rod.Due to anode deadweight and Slurry pump in electrolysis production, aluminium-aluminium weld and the explosion block steel-aluminium contact surface of aluminium guide bar and explosion block often occur snapping phenomenon, particularly after the increase of insulation material thickness is extremely gone up in the production of employing low voltage, the load of anode rod and explosion block increases greatly, snap phenomenon to take place frequently, thus cause a large amount of aluminium guide bar groups to roll off the production line maintenance.
Aluminium guide bar and steel aluminum explosive weld block junction often adopt the welding process beating groove in addition, maximum defect be face of weld little and due to two weldments thickness difference larger, arc heat can not be distributed well again in welding process, easily cause aluminium guide bar groove face to fuse saturating, welding strength causes the aluminium guide bar group maintenance rate that rolls off the production line high not.
In electrolysis production process, need to change steel crowfoot because ionogen steel pawl causes, anode rod group also can be caused to roll off the production line maintenance.
Existing maintenance mode is first cut open by its weld seam II with gas cutting, then saw lower steel aluminum explosive weld block and small part guide rod with a chainsaw, again welds after finishing aluminium guide bar bevel for welding with new steel-al blasting block.Roll off the production line in the process of maintenance in anode rod group, due to cutting aluminium guide bar repeatedly, aluminium guide bar can be made to shorten gradually until off technical requirement.The welding process that groove is directly connected with steel aluminum explosive weld block beaten by employing guide rod, the length between aluminium guide bar and steel aluminum explosive weld block can not be changed, aluminium guide bar length after repeatedly maintenance is inadequate, is forced to roll off the production line melt down remelting and reduce life cycle, adds maintenance cost.
Summary of the invention
The invention provides a kind of welded construction extending anode rod life cycle, that it changes the welding process that groove is beaten in aluminium guide bar and steel aluminum explosive weld block junction, overcome welding technique defect in aluminium industry, improve welding strength, reduce the repair rate of aluminium guide bar group; Meet aluminium guide bar length to be beyond one's reach under conventional techniques electrolysis production technical requirements simultaneously, extend the life cycle of aluminium guide bar.
For solving above technical problem, the invention provides following technical scheme: a kind of welded construction extending anode rod life cycle, described anode rod comprises the aluminium guide bar, steel aluminum explosive weld block and the steel crowfoot that connect successively, between aluminium guide bar and steel aluminum explosive weld block, add the aluminium web plate that multi-disc parallel side-by-side is arranged, the two ends of every sheet aluminium web plate are welded between aluminium guide bar and steel aluminum explosive weld block respectively.
Further, described aluminium web plate is of a size of: 145 × 90 × 7mm.
Further, between described aluminium web plate, there is space.
Further, described every sheet aluminium web plate is all vertical with steel aluminum explosive weld block with aluminium guide bar.
The welded construction of this prolongation anode rod life cycle that the present invention relates to, employing is added aluminium web plate and is superposed the mode of welding between aluminium guide bar with steel aluminum explosive weld block, add the efficient weld area of aluminium guide bar and steel aluminum explosive weld block, and the length extended between aluminium guide bar and steel crowfoot, in maintenance in the future, melt down remelting without the need to causing rolling off the production line because aluminium guide bar shortens gradually.In addition, the increase of the useful area of welding makes welding strength improve, and reduces the generation of snapping phenomenon.
