| BOF steelmaking process automation control is designed to be efficient smelting of the steel-making methods to maximize the potential to reduce the operator’s labor intensity, lower production costs, refining process to reduce human intervention significantly improve the quality of steel production of high value-added products and lay a solid foundation. Between the current computer science,electronic technology, communication bus technology, control theory,artificial intelligence technology, widely used in metallurgical industry, for precision data acquisition, real-time to improve, making it the task of all steelmaking operations by automatic control system independently become a reality. Will be able to make our steelmaking process control technology has reached international advanced level.In this paper, Shougang Hebei Iron and Steel Co. Qian’an210t converter steel-making automation a key control system for the background hit rate for improved refining end, the access to a large number of relevant literature, based on an overview of the development of automated control systems steel course, the dynamics of automated static control of steel-depth research, mainly done about several aspects:(1) Design and research210T converter steelmaking automation control system, Controller PLC and fiber Ethernet-dimensional structure of the control system design, Further detailed analysis of steel-making automation system functions under the premise of total automation to the design of steel-making system. Overview of the development process of steelmaking automation.(2) Detailed analysis of sub-lance and gas equipment and systems for its control and application of the smelting process to extract the relevant data for computer analysis and processing and critical data into the control system to guide the level of refining and smelting to improve accuracy.Study of sub-lance and gas analysis system, the sub-lance and the gas system for the vice hardware equipment and automatic control of the main logic, blowing mode, the control elements involved in the design and application of sound.(3) Combined steel production process control of blowing the static model, dynamic model for in-depth study and control the production of steel involves the automation of content-related assistance and possible problems were analyzed. Automation and process steel-making raw data model system to determine, especially for critical slagging system model, material balance, heat balance to determine, at the same time control the converter end mathematical modeling. |
