Process and Assembly Method of Cathode Steel Rod with Slit at Golden Section Point

Abstract

A cathode steel bar machining and assembling method achieved through seam opening according to the golden section ratio comprises the following steps that firstly, a position line for assembling the end of a cathode carbon block is marked off in the length direction of cathode steel bars, a center line of a continuous seam needing to be machined is marked off in the height direction according to the golden section ratio, namely the 0.618H position, the length of the continuous seam is 0.6 time that of the joint position of the cathode steel bars and the cathode carbon block during cathode steel bar assembling, and then the continuous seam is milled out according to the marked-off length and height positioning line; secondly, the cathode steel bars are hung in a cathode carbon block groove, the larger face which is 0.618H end, distant from the cathode steel bars, of the continuous seam faces the cathode carbon block, the position line for assembling the end of the cathode carbon block is aligned to the end of the cathode carbon block, the upper surfaces of the cathode steel bars are level to the surface of the cathode carbon block, finally steel bar paste is filled and tamped densely, and a cathode carbon block is assembled. According to the method, seam opening standards of the cathode steel bars are unified, level current density during production is effectively blocked, current distribution is improved, current efficiency is improved, and energy loss is reduced.

Description

Technical field: [0001] The invention is applied to the construction and production of electrolytic cells in the electrolytic aluminum industry, and particularly relates to a method for processing and assembling cathode steel rods with slits at golden section points. Background technique: [0002] Aluminum electrolytic cell is a kind of production equipment with high energy consumption. The production current often reaches hundreds of thousands of amperes. Therefore, a large horizontal current will inevitably be generated during the production process, causing violent fluctuations in the aluminum liquid, thereby affecting the stability of production. , and generate a large amount of reactive power consumption. [0003] The process of slits on the cathode steel rod can block the horizontal current density in production, improve the current distribution, and increase the current efficiency. However, there is currently no uniform standard for the slit of cathode steel rods in ...

Problems solved by technology

However, there is currently no uniform standard for the slit of cathode steel rods in the industry, which leads to limited suppression of horizontal current during production and operation, the improvement of current efficiency is not obvious, and the reactive current is still relatively large. In extreme cases, even sudden changes in horizontal current and cathode steel Malignant phenomena such as rod fusing and cathode carbon block rupture
