英文摘要： Iron and steel industry is one of the pillar industries in the national economyof China, which is also an industry with high energy consumption and high emissionthat is dominated by the iron making process of blast furnaces.In the optimizationof blast furnace production, burden distribution plays a fundamental role, which is characterized by complicated operation mechanism, poor environment,difficultiesin the detection of key states and the optimization of production index. This project will develop new methodologies for the modeling, optimization and control of burden distribution process based on burden distribution control.The objective is to keep the proper operation of blast furnace and to optimize the production index. The details are as follows:. 1. Relationship between the production index and blast furnace status, and therelationship between the blast furnace status and the parameters in burden distribution;. 2. Methods of detection and reconstruction for the burden surface shape and gas flow distribution;. 3. Method of hybrid dynamic modeling based on mechanism analysis and data driven approach;. 4. Production index optimization methods for the furnace status diagnosis, evaluation and optimal setting; . 5. Control method for the process in which the blast furnace runs continually while the burden distribution executes only intermittently;. 6. Real-time visualization and simulation platform as well as application system;. This project will reveal the relationship between the production index and theburden distribution process, and lay the foundation for the full automation and visualization of blast furnace burden distribution process. As the outcome, a set of new theories, methods and technologies will be established for the modeling andcontrol of complicated production process that can optimize the production index and significantly contribute to the energy saving and emission reduction. . In summary, the project is significant scientifically and promising in engineering applications.
