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 the database; 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 in particular relates to an online control method for steelmaking and continuous casting. Background technique [0002] The production process of steelmaking and continuous casting is mainly based on the daily production plan issued by the planning department of the MES layer. The raw materials such as blast furnace molten iron and scrap steel are passed through the converter (melting steel smelting), refining furnace (molten steel refining) and continuous casting machine (molten steel shaping). billet drawing) and other processes to produce billets of certain specifications and provide raw materials for the hot rolling production process. [0003] The production process of steelmaking and continuous casting has its particularity. Its main performance is that the production plan must be executed sequentially, and there is a certain limit on the completion time. The ...
