Design and application of digital management system for the sinter raw material plant
To solve the problems existed in iron and steel enterprise material plant, such as complex sources resulting in variety of materials, inaccurate inventory statistics leading to high cost, unpredictable external factors affecting material plant, etc., a digital management system is introduced in this paper. Firstly, the practical requirements and the process of material plant are analyzed. Based on the analysis, the new grid management and material balance methods are developed. Applying these methods, a new management system for material plant is designed, whose system configuration, hardware architecture, data flow, and functions of modules are introduced in details. Such system has been implemented in a large-scale iron and steel corporation sinter raw material plant. The operation results show that, this system has excellent capabilities and a promising application future in industries.
Design of a digital management system for the sintering material ground
There are many kinds and a large number of raw materials in the sintering material ground to be managed, while it is difficult to obtain the precise inventory values, which often leads to high cost. Furthermore, the external factors of material ground are difficult to handle, such as weather variation, order fluctuation, measurement failure and so on. To solve such raw material management problems, a digital management system has been developed. First, the practical requirements and the raw material management processes are analyzed. Then, optimization and prediction methods are used to calculate the inventory according to the practical situation. With the help of practical technologies and production conditions, the developed system has been applied to a large-scale sintering material ground. The practical running results of the application demonstrate the validity of the proposed digital management system.
SR topography of plastically deformed Fe-Si bicrystals - observation in situ and post mortem
SR reflection topography was applied to study the interaction of slip dislocations with the grain boundaries in Fe-4at%Si bicrystals deformed by compression. Three experimental settings with either a white or monochromatic beam were used and the corresponding orientation contrast analysed. Dislocation transmission through the grain boundary was observed in bicrystals with favourable geometry of the slip systems.
