Description
Technical field
The present invention relates to aluminum electrolysis technology field, a kind of cathode steel bar total cross-section bonding machine is related in particular to.
Background technology
During Aluminum Electrolysis Production, no matter the electrolytic cell of newly-built electrolytic cell or overhaul, its cathode steel bar is required for
Welding.At present, it is general using steel in flakes by the way of weld, i.e., one layer of steel is inserted in the middle of weld seam in flakes afterwards using common welding machine hand
Work welds steel both sides in flakes, and the removal welding slag that stops, the basis after removal welding slag in last layer steel in flakes are needed after having welded one layer
On weld next layer again, successively weld steel in flakes until by whole weld seam weld complete.Such welding cost is although low, but steel
Do not fused completely with cathode steel bar mother metal in flakes, due to being influenceed by electrolysis bath circumference magnetic field, common welding machine is it is difficult to ensure that weldering
Seam quality, and be difficult to control to by the fluctuation welding quality of welder technology and sense of responsibility, typically can only achieve cathode steel bar whole
50% or so of bulk area.In actual use, commissure resistance and pressure drop are larger, can cause electrolytic cell bias current, influence whole electricity
Solve the stabilization of groove；On the other hand ton aluminium direct current consumption can be caused again to be increased, and increases cost.
In order to solve the above-mentioned technical problem, following technology is proposed in the prior art：
Chinese patent notification number is used to be electrolysed to disclose one kind on June 25th, 2016 in the prior art of " CN205254317U "

Frame, the top in cabinet is provided with wire guide.The welding equipment have easy to operate, high degree of automation, can
Save cost of labor and the advantage of welding efficiency can be greatly improved, but in actual use, the patent is still present as follows
Defect：First, the welding equipment volume is big, and weight is big, when being welded in entrance electrolytic cell, need to be lifted by overhead traveling crane, in electrolytic cell
Interior welded cathode rod iron, when moving to next station, workman promotes welding tractor very laborious, when head is not in cathode steel bar
During top, workman need to back and forth promote dolly adjustment position, waste a large amount of muscle power and time.2nd, welding head and guidance panel away from
From farther out, workman cannot manually adjust the position of head and consumable nozzle while guidance panel is operated, workman in guidance panel and
Hurried back and forth back and forth between head, increase labor strength.3rd, head is without consumable nozzle angular adjustment, due to the rod iron edge that cuts not
Vertically, when cathode steel bar is assembled, to avoid consumable nozzle and rod iron EDGE CONTACT, the group of rod iron can be increased to gap, increased weldering
Seam loading, extends weld interval, increases welding cost.
