Design Of Alumina Production Scheduling Optimization System Based On Characteristics Of Production Cycle

On the background of production process of alumina in Guizhou Branch China Aluminium, the characteristics and existing problems, and through the analysis of the production process, the integrated optimization and control system of alumina production and the bottom layer between the upper management system and control system of information, based on the production cycle of alumina scheduling optimization system solutions was put forward, we design and implement the optimization of alumina process, and the basic framework of the system in database as the core.On this topic, this paper mainly completed the following several aspects of the research work:①Analysis the requirements and characteristics of alumina production scheduling system, and summarizes the current alumina production process problems and the faults, based on the production cycle of alumina scheduling optimization system solutions was put forward.②Completing alkali ratio, calcium, water quality index predictive control charts. Mainly include ingredients of the analysis of the technology and the problems existing in the course of quality, the mechanism of the model and based on the theory of fuzzy raw mix slurry intelligent correction model were set;③Realizing on-line accurate detection of ratio of soda to alumina(RSA) and leaching rate(LR). Mainly including high-pressure dissolving mechanism analysis, the mechanism model of RSA and LR.and based on principal component analysis of the neural network model was set,the research of composite neural network algorithm, the effect of the model in the commissioning;④Designing the basic framework of the alumina scheduling optimization system. Mainly including the design of network system, the selection of hardware equipment, platform of real-time/historical database and the development of application system。This topic is mainly research based on the production cycle of alumina production scheduling system,A good solution to the "information ground fault" between the upper management and the bottom control,and the "information island" problem"of the bottom control systems.Realizing the static and dynamic unification of the company production management and the comprehensive unification of the management and control,As the application example,Based on the alumina production scheduling system has been put into operation in guizhou branch, China Aluminium and achieved good effect.
