Study On The System And Model Of Knowledge Webs To Continuous Casting-Continuous Rolling In Iron And Steel Enterprises

Continuous casting-continuous rolling (CC-CR) is at the stage of researching and developing in our country while in others is developed. Since there are greater differences on nature in between steel-making process and process of steeling rolling, thus serious different steps have existed in conformity and harmonization between the two processing. In this paper, the mathematics models were firstly drawn out for optimizing production schedule and assisting production scheduling, then decisions were made by genetic algorithm (GA) while some impacts happened in the processing to optimize the planning and assist to schedule producing in order to improve the capacities to compete and reply.Starting with from steel producing characteristic in this thesis, the things of iron and steel enterprise and developing state at present was analyzed, and according to the form and characteristic of CC-CR that CC-CR is to the mainstream of cast rolling and producing to iron and steel enterprises in the future was pointed out on the base of the current situations and development trends to CC-CR managing and producing integrated at home and abroad.The technological process of CC-CR was analyzed and some constraints were summed up according to the sequence and technological requirement of continuous casting and continuous rolling, and then on the base some mathematic model were built such as the production schedule model which meets the production contract, simplified model of production schedule to optimum stove, simplified model of production schedule to optimum casting, the production schedule model which works out optimum texture of steel products in hot rolling plan of production schedule, etc.Standing on the current situations and development trends to CC-CR produce and management integrated at home and abroad, how to integrate better CC-CR was explored and studied, and the CC-CR information flow model was put forward. On the base of analyzing the pull-buffer-thrust in the steel-making course, planning and scheduling logic diagram to the system of knowledge webs on CC-CR producing was drawn out, and the structure chart to assist producing by the computer was provided, and the flow chart to select the produce mode, the flow chart to schedule the steel rolling producing and the block diagram for overhauling and arranging integrated were given.The system of knowledge webs on CC-CR producing was three layers of structure of B/S mode by the dynamic network ASP technology, and its database was used SQL Server 2000 database to support. Considering many varieties, little batch in customer's contacts and the link-up and swiftness of response to the procedure, the system of knowledge webs on CC-CR producing was adopted the storing data process technology to deal with while joining the mutual data with the database in succession and also use GA to solve some real Non-Polynomial problems when transfer the relevant mathematics model imbedded and ask solving.
