Preparation process of special solid conductive plate and bus board for electrolysis

Abstract

The invention relates to a preparation process of a conductive plate or a bus board, in particular to the preparation process of the solid special conductive plate or the bus board which are applied to an ISA (Industry Standard Architecture) method novel electrolytic process. The preparation process of the solid conductive plate or the bus board comprises the following steps of: (1) preparing special cast ingots which respectively have the same shape of the solid conductive plate or the bus board; (2) preparing blanks of the solid conductive plate or the bus board by using a two-roller reversible hot rolling mill; (3) stretching the blanks; and (4) refining and cutting into a finished product. By adopting a production process of matching the rolling of the special cast ingot with stretching to replace the traditional production process of machining a flat plate, the invention can solve the problem of the production process of the large-size solid special conductive plate or the bus board which are required by the ISA method novel electrolytic process introduced by foreign countries and are provided with two rows of continuous conductive ribs. By adopting the invention, the solid special conductive plate or the bus board which are applicable for the ISA method novel electrolytic process can be prepared.

Description

technical field [0001] The invention relates to a preparation process of a conductive plate or a bus plate, in particular to a preparation process of a solid special-shaped conductive plate or a bus plate used in the new electrolysis process of the ISA method. Background technique [0002] In the process of copper electrolysis, according to the principle of copper electrolysis, increasing the current density is an effective way to obtain high-grade electrolytic copper. Now many large copper smelting enterprises have adopted the "ISA new electrolytic process" imported from abroad to prepare high-grade electrolytic copper. The prominent feature of this process is the use of high current density electrolysis. Generally, the output voltage of the rectifier is relatively low, but the output current is relatively large. Taking the third-phase technical renovation project of Guixi Smelter of Jiangxi Copper Group as an example, it adopts the new electrolysis process of ISA method. ...

AI Technical Summary

Problems solved by technology

[0003] At present, the production technology of large-scale solid copper conductive plates and manifolds for electrolysis is still blank in China. The conductive plates and manifolds required by the traditional electrolysis process are directly using flat plates or individually punching discontinuous conductive packs on the basis of flat plates. However, the conductive plates and manifolds produced by this method are small in size and poor in forming accuracy, which can only meet the requirements of the traditional electrolysis process. For the large specifications required by the "ISA new electrolysis process" imported from abroad The problem of the production process of the solid special-shaped conductive plate with continuous conductive ribs and the manifold has always been a blank in China.
