Steelmaking second-stage process control system and steelmaking second-stage process control method

Abstract

The invention discloses a steelmaking second-stage process control system and a steelmaking second-stage process control method. The steelmaking second-stage process control system is connected with an MES and receives operation indications issued by the MES, molten iron plan matching is carried out according to the actual performance of production, and real-time process data of production are obtained from a converter, a refining furnace and a continuous casting basic automation system in a fixed period mode in the production process. The steelmaking second-stage process control system comprises a production indication module, a progress management module, a production actual performance module, an ingredient management module, an operation actual performance module, an iron steel ladle management module, a standard management module and a statistic analysis module. According to the steelmaking second-stage process control system and the steelmaking second-stage process control method, a large number of data in all production line PLCs in an industrial net are safely and rapidly uploaded to the second-stage system in an office net, the aims of strengthening the management level of a steel mill, controlling the material consumption, reducing the cost of steel per ton and reasonably dispatching processes are achieved, and the economic efficiency and the whole competitive capacity of an enterprise are improved.

Description

technical field

[0001] The invention relates to the fields of steelmaking automation and information technology, and particularly designs a secondary steelmaking process control system and control method. Background technique

[0002] The steelmaking plant is located in the key part of the product production process. The internal process of the steelmaking plant is complex: including important processes such as converter steelmaking, refining, and continuous casting; the outside is connected with ironmaking and steel rolling. Some of the existing technologies use a secondary system to improve the production operation management mode and reduce production costs, but the cost of the secondary system in the prior art is too high; at the same time, it cannot meet the actual production needs of different sites, resulting in the system not being able to fully play its role. In the prior art, each control system of the steelmaking plant is in a decentralized and independent state. ...
