Online steelmaking continuous casting control method

Abstract

The invention relates to an online steelmaking continuous casting control method, belonging to the technical field of steelmaking continuous casting; the method comprises the following steps: an interface management server is in network connection with a site controller, and stores the acquired various state information and process data in a database after data processing and format conversion, and also stores the production method delivered by the upper system in the database; a database server stores the production site real-time process data, planning data and various system configuration data in the database; an application server executes the steelmaking continuous casting production online control method, acquires data from the database server and stores the regulation result in thedatabase; a client workstation displays various data, conducts the query of routine data, stores the data in a local computer and accordingly realizes the offline analysis of data; the online steelmaking continuous casting control method has high solving speed, higher automation degree, can preciously adjust to minutes, reduce the manual adjusting times and molten steel redundant waiting time.

Description

Technical field [0001] The invention belongs to the technical field of steelmaking and continuous casting, and particularly relates to a method for on-line control of steelmaking and continuous casting. Background technique [0002] The steelmaking and continuous casting production process is mainly based on the daily production plan issued by the planning department of the MES layer. The raw materials such as blast furnace hot metal and scrap are passed through the converter (steel smelting), refining furnace (steel refining) and continuous casting machine (steel molding) The process of drawing billet) produces a certain specification of cast billet, and provides raw materials for the hot rolling production process. [0003] The steelmaking and continuous casting production process has its particularities. Its main manifestation is that the production plan must be executed sequentially and there are certain restrictions on the completion time. The overdue waiting between stations ...

Problems solved by technology

None of the above-mentioned patents is aimed at different production abnormalities in the production plan of steelmaking and continuous casting, especially for continuous casting machine interruptions and conflicts, converter equipment failures that lead to a mismatch between converter and continuous casting machine production capacity, and non-continuous casting time. In the case of deviation, etc., there is no online optimization and adjustment method for local time and global time,
