In order to solve prior art Problems existing, design of the present invention is:
For a manufacture method for the electrode shell of large-scale furnace of calcium carbide, comprise the steps:
1.. with plate shearing machine, cold-reduced sheet is cut into the steel plate that thickness is all size of 3mm;
2.. adopting veneer reeling machine the steel plate of described step 1 to be rolled into diameter is 1500 ~ 1700mm, is highly the housing of 1500 ~ 2000mm;
3.. adopt forcing press and bender described step 1 light plate to be made the satisfactory gusset of upper and lower two end band fixing holes;
4.. adopt hydraulic press that the steel plate of described step 1 is made fixing backing plate;
5.. adopt CO
2gas shielded arc welding by the case weld of the gusset of described step 3 and described step 2, wherein at case inside circumference uniform welding 14 ~ 18 muscle sheets of described step 2;
6.. the housing of upper and lower described step 2 is connected with the lower end fixing hole of the muscle sheet on the housing of step 2 described in upper end by bolt by the fixing hole of the upper end of the gusset of described step 3, the body height of described step 2 is 1500 ~ 2000mm, and the total length of the muscle sheet of described step 3 should be 1780mm ~ 2280mm;
7. the fixing backing plate of electric resistance welding by the described step 4 inside the junction at upper and lower for the housing of described step 2 two ends and the case weld of described step 2 is adopted;
8. the fixing backing plate of described step 4 is docked with the housing of upper and lower described step 2 respectively by connecting plate.
Beneficial effect of the present invention: be respectively equipped with fixing backing plate inside the upper and lower two ends of housing of electrode shell, docked by connecting plate between adjacent two shell rings, change the connected mode that traditional electrode shell adopts socket joint, improve bonding strength, improve processing and manufacturing efficiency simultaneously; The fixing hole of gusset upper end is connected with the fixing hole bolt of the gusset lower end of the shell ring of its upper end, and gusset is connected firmly each other, the rigidity of whole electrode shell is improved, ensure that the steady production of large-scale furnace of calcium carbide, reduces furnace of calcium carbide accident and occurs.Fully contacted with pressure rings by electrode shell outer surface, the conduction shortcoming of the linear contact lay of overcoming over, expands conductive area, ensure that the demand of large-scale furnace of calcium carbide high power conductive.
Manufacture method of the present invention can the electrode shell of manufacturing process complexity, improves electrode shell precision.
