A New Operational Pattern Optimization Method and Its Application in Nonferrous Metallurgy
Abstract:
Considering the difficulties of optimizing the operational parameters of the nonferrous metallurgical process, a new operational pattern optimization method is proposed, which introduces product quality and energy consumption index. Principle Component Analysis (PCA) is used to simplify the operational patterns, reduces the data dimension and overcomes the low efficiency of the operational patterns caused by huge pattern database. After the attribute reduction of PCA, the weighted attribute coefficient of the new variable is solved and a new hybrid similarity calculation method is presented, which greatly improves the speed and accuracy of pattern matching. When the pattern is reused, each matched pattern weight can be identified according to the energy consumption, which is helpful to lower the energy consumption of the nonferrous metallurgical process. Simulated experiments are carried out in terms of the real production data. The Simulated results indicate that this novel method is a promising and effective technology to be applied to the real industrial process to reduce the zinc dust consumption and increase the qualified rate of the outlet cobalt ions.
