Abstract
The invention discloses a stainless steel negative plate conducting beam for copper/nickel wet electrorefining or electrodeposition. The conducting beam comprises a copper bar and a stainless steel pipe, wherein the copper bar and the stainless steel pipe are compositely connected in a cold extrusion mode, the stainless steel pipe is tightly coated on the surface of the copper bar, and the copper bar at the two ends of the conducting beam is milled out. The internal and external surfaces of the stainless steel pipe serving as a bearing beam are subjected to acid pickling and polishing treatment so as to remove impurities affecting the conductivity, then the stainless steel pipe and the copper bar are tightly composited by using a special-shaped mold cold extrusion method so as to form a copper-clad steel composite conducting beam, and the resistance of a bonding interface between the steel bar and stainless steel is small, therefore, the conductivity of the conducting beam is good and the current efficiency can reach 97-99%.
Description
Technical field
The invention belongs to the non-ferrous metal metallurgy technical field, be specifically related to a kind of copper, the refining of nickel wet method electrolysis or electrodeposition stainless steel cathode plate conducting beam.
Background technology
In traditional copper, electronickel refining or electrodeposition process, electrorefining or stainless steel cathode plate current efficiency lower (95%～96%) for electrodeposition, bath voltage is higher, structural relation with the negative plate conducting beam is close, in the preparation process of traditional technology composite conducting beam, the compound undertighten of copper and stainless steel, compound interface place resistance is larger, in actual production process, current efficiency is lower, and production cost is higher.
1979, Australian PERRY IAN JAMES invented the method that replaces traditional copper starting sheet with stainless steel cathode plate, has configured special-purpose cathode conductive structure simultaneously, through facts have proved that there is following shortcoming in this kind of syndeton:
1, adopt the square-section stainless steel tube as current conducting rod and carrier bar, the stainless steel profiled material needs customized specially, causes starting material and tooling cost to rise, and stainless processing characteristics is also bad in addition;
2, stainless steel surface needs first nickel preplating, re-plating copper conductive layer, and operation is more, and binding force of cladding material is also good not;
3, stainless poorly conductive, cause the volts lost of whole conducting position to increase.
Summary of the invention
The problem existed for prior art, the object of the present invention is to provide a kind of simple in structure, copper, the refining of nickel wet method electrolysis or electrodeposition stainless steel cathode plate conducting beam that conductivity is good.
Technical scheme of the present invention: a kind of stainless steel cathode plate conducting beam, described conducting beam comprises copper rod and stainless steel tube, described copper rod and stainless steel tube are by cold extrusion mode composite joint, and described stainless steel tube closely is coated on the copper rod surface, and described conducting beam two ends mill out copper rod.
Further, described conducting beam two ends mill out the copper rod that 100～150mm is long, 11～14mm is wide, 5～8mm is high.
Further, described copper rod is the square bar that pure red copper is made.
Further, the transversal face width 11～14mm of described copper rod, high 37～45mm.
Further, described stainless steel tube is that the 316L stainless steel is made.
Further, described stainless steel tube thickness of pipe 2～3mm.
Beneficial effect of the present invention:
(1) the affected carrier bar of stainless steel tube for the present invention, supporting effect is better.
(2) conducting beam stainless steel tube of the present invention inside is after pickling, polished finish, compound with the red copper bar cold extrusion, and stainless steel and red copper bar are in conjunction with tight, and bonding interface resistance is less, and electroconductibility is better, and current efficiency can reach 97%～99%.
