Research Of Craft Process Controlling In350KA Aluminum Reduction Cells

In the current domestic aluminum electrolyze roasting process, mostly adopt manual installation and removal of the shunt plate. Not only inefficient, but also cannot achieve the quantitative and accurate control. Development of automatic control system of aluminum reduction cell in baking, not only can improve the control accuracy of baking start-up, prolong the service life of aluminum electrolytic cell, but also has profound social significance for energy-saving emission reduction current social advocacy. At the same time, also has the very good economic efficiency.The content of the thesis is the Aluminum Inc China Power Investment Corp project consigned by the " North China University of Technology Nonferrous Metallurgy Research Center research group undertake part of automatic control system development"350KA electrolyze roasting.This paper has improved the baking process controller on the basis of previous work, and applied to the roasting Qingtongxia Aluminum Inc electrolytic two No.9210slot boot process. The start by using the automatic flow control system of North China University of Technology university development, comparative experiments were performed in a partially preserved traditional shunt sheet, achieve the expected effect.In this paper, from the process point of view, process is closely related to the study of baking start-up and automatic distribution system. Research on how to adjust and set up automatic distribution system can better meet the site to start the needs of practice, through the summary and the analysis to start practice, put forward the improvement of automatic distribution system used in the practice and optimization measures. And through the optimization and adjustment, how to formulate corresponding regulations to guide the future practice of baking and start-up, the research group developed the automatic distribution system can be more widely used.For the improvement of automatic distribution system, mainly from two aspects of mechanical part and control system part are. Secondly, start by roasting Qingtongxia Aluminum Inc electrolytic two No.9210electrolytic aluminum process show, process standardization research shunt system automatically for aluminum electrolytic tank can play the role of precise control. Research results will gradually become a mature equipment market.
