现代大型高炉料面特征建模理论与方法研究

Iron and steel industry is one of the pillar industries in the national economy of China, and blast furnace iron making process is the basic production process of the iron and steel industry which is significant for the energy saving and consumption reduction. The shape of the blast furnace surface and its change process are closely related to the blast furnace condition. Currently, the relationship between them relies on the operator's experience to direct the production process in the results of the uncertainty of the blast furnace iron making process. It causes the high energy emission. This project will aim at the design and development of the theory and methods for the blast furnace surface modeling based on the complex blast furnace condition and the surface feature extraction during the blast furnace production process. The project will establish a new system to represent the surface model and define the characteristic parameters of the blast furnace surface from the height of the blast furnace to the longitudinal section line of the blast furnace surface until the 3D surface shape reconstruction. The research will investigate the model and algorithm of the relationship between the characteristic parameters and the furnace condition parameters of the blast furnace. The project will reconstruct the 3D surface model combined with the mechanism model of it based on our research results of the detection technology about 3D surface measurement and the real time phased array radar data. The surface clustering and matching algorithm will also be investigated in the research in order to establish the history information database of the blast furnace based on the combined information of the characteristic parameters of the surface and the furnace condition parameters of the blast furnace. The research will be a systematic study and theory of the blast furnace surface and it will radiate the related research fields. The research results have important theoretical significance and application value for the automation and visualization of the burden distribution control of the blast furnace together with the energy saving and the emission reduction.
