Prebaked anode scrap quality tracing method

Abstract

The invention relates to an anode scrap quality tracing method, in particular to a method for tracing quality of a prebaked anode scrap used for aluminum electrolysis. The method includes that data about dimension, crack condition and crack position of each anode scrap tested by an anode scrap test station of an electrolysis plant are input into an electrolysis plant server; an assembly plant anode scrap cleaning test station tests cleaning condition of each anode scrap and inputs result data into an assembly plant server; all anode scrap related indexes stored in the electrolysis plant server, the assembly plant server and a quality test center server are sent to a carbon factory data processing and quality tracing server through data conversion middleware, and at the same time, the results are directly sent to a client side server. The prebaked anode scrap quality tracing method has the advantages that prebaked anode quality is improved, service life of a baking furnace is prolonged, and production management and operation costs are lowered.

Description

technical field [0001] The invention relates to a method for tracking the mass of anode residues, in particular to a method for tracking the mass of anode residues of prebaked anodes used in aluminum electrolysis. Background technique [0002] As one of the main raw materials for the production of prebaked anodes, prebaked anode remnants have a direct impact on quality indicators such as the mechanical properties of prebaked anodes, the life of the roaster, and the anode net consumption index. The most intuitive reflection of anode quality and its entire production status. Therefore, the quality control of anode butts is one of the key issues that determine the quality of prebaked anodes and the life of the roaster. Effective tracking and monitoring, once there is a problem with the cleaning of the anode residue, it will easily lead to: [0003] 1.

Problems solved by technology

Therefore, the quality control of anode butts is one of the key issues that determine the quality of prebaked anodes and the life of the roaster. Effective tracking and monitoring, once there is a problem with the cleaning of the anode residue, it will easily lead to:

[0003] 1. A large number of soft anode residues are returned to the production system, which directly affects the quality of prebaked anodes, resulting in a large amount of carbon residue in the electrolytic cell, which in turn affects the performance of the electrolytic cell

[0004] 2. A large amount of Na, Ca and other prebaked anode reactive catalytic elements contained in the residual electrode not only increase the net consumption of the prebaked anode, but also lead to a high level of greenhouse gas emission from the electrolytic cell, and the Na element contained in the residual electrode is depleted during the anode roasting process. It will erode the refractory material of the roaster and affect the service life of the roaster

[0005] In addition, a large amount of key information reflecting the quality of the prebaked anode and its production process control, such as the dimensions of the anode butt and the condition of cracks, cannot be used in time, which affects the production and operation cost of the entire prebaked anode
