Abstract

The invention relates to a management method of electrolytic aluminum, in particular to a management method of an electrolytic aluminum whole life cycle. The management method comprises the stages oftank building, roasting, starting, normal production operation and tank stopping. In the tank building stage, during construction, construction standards and technological requirements are set up forconstruction units, and construction information is managed and recorded; in the roasting stage, during roasting, material information, operation information and tank condition information of an electrolytic tank are recorded; and in the starting stage, during starting, operation parameters of the electrolytic tank are recorded and monitored. The management method has the advantages and effects that in the operation stage of the electrolytic tank, a mathematical model is built for the electrolytic tank, and analysis factors of several core parameters of the electrolytic tank are built correspondingly, so that the purposes of prolonging the life of the tank and improving the electrolytic production efficiency are achieved.

Description

technical field [0001] The invention relates to a management method of electrolytic aluminum, in particular to a management method of the whole life cycle of electrolytic aluminum. Background technique [0002] Aluminum electrolysis is a typical continuous process industry. Product Life-Cycle Management (PLM) runs through the five stages of the entire life cycle of the electrolytic cell, namely, the cell building stage, the roasting stage, the start-up stage, the normal operation stage, and the shutdown stage. In the tank stage, the key data parameters of the electrolyzer at different life stages are collected, covering equipment, energy, laboratory, material, measurement and other major categories of data that affect the operation of the electrolyzer, and the mathematical model of the electrolyzer is established. The current manufacturing execution system of the electrolytic aluminum plant only focuses on the normal production and operation stage of the electrolytic aluminu...
