A quality traceability management method for the whole production process of carbon anode for aluminum

Abstract

The invention discloses a quality traceability management method for the whole production process of carbon anodes for aluminum. By assigning physical identity attributes to carbon anodes, the matching and correlation of information including process parameters in the production and use of carbon anodes and time correspondence are realized; through the development of identity Endow physical attributes with machine vision recognition equipment to realize the tracking of physical attributes; through the means of developing system software, complete the storage, conversion and preprocessing of production process information data; finally, through data mining and machine learning, establish the quality of carbon anode production process system prediction model. Through the development of the above-mentioned related devices and system development, the present invention can optimize the technical parameters of the production process, realize the precise correspondence and association between the process data and the anode production batches, and find out the cause of the problem if there is an anode and quality problem, and solve the problem. Adjust in time to improve the quality of anode production, reduce the unqualified rate, and increase the rate of first-class products.

Description

technical field [0001] The invention relates to a quality traceability management method for the whole production process of carbon anodes for aluminum, belonging to the technical field of aluminum electrolysis. Background technique [0002] In the electrolytic aluminum production process, the carbon anode is the heart of the aluminum electrolytic cell, so the quality of the anode is very important to the electrolytic aluminum production. The quality of the anode is directly related to the stability and efficiency of the electrolytic production process. In the electrolytic production process, if the quality of the anode is poor, it will directly affect the consumption of carbon anode; As the temperature rises, the current efficiency decreases and the power consumption increases. Therefore, how to effectively improve the quality of the anode and reduce the consumption of the anode is an important problem to be solved urgently for the production enterprises of electrolytic a...

Problems solved by technology

[0005] However, the above existing technologies do not consider the following issues: the production process of carbon production enterprises is relatively long, and from the perspective of material circulation, it mainly includes raw material storage, petroleum coke calcination, green anode manufacturing, roasting, carbon block transfer and other links

The evaluation of anode quality is closely related to the technical parameters and raw materials of each production link. However, in the current production process of carbon anodes, production technicians conduct correlation analysis on anode quality indicators and production process parameters based on experience, and there is a lack of quality influencing factors. Overall, multi-factor analysis, when there is a problem with the quality of the anode, it is impossible to accurately find out the cause of the factors affecting the quality, and even an unreasonable production decision of "headache, head, foot, pain, foot", etc., it is easy to judge only by the experience of production technicians Mistakes occurred, and the experience of different technicians was different, so the production process of aluminum anodes lacked a complete set of perfect quality traceability management methods, resulting in frequent quality accidents, low anode pass rate, and low first-class product rate
