Steel-making production process intelligent scheduling method

Abstract

The present invention discloses a steel-making production process intelligent scheduling method which comprises the steps of (1) inputting a production plan which comprises a production order and a hot delivery and hot charging production plan given by a hot rolling workshop, (2) decompositing a working plan, calculating the number of slabs, and decompositing the order according to steel types, slab specifications and delivery dates, (3) scheduling a cast order, and scheduling each casting according to a continuous casting machine usage condition and the difference between order delivery dates, (4) collecting a characteristic signal and obtaining bottom layer equipment key position characteristic signal through a corresponding sensor, (5) executing a crane preferred algorithm, (6) switching a transport task state, (7) rearranging a plan, and (8) displaying the rearranged plan to dispatchers in the form of a Gantt diagram. According to the method, the production safety in the steel-making process is ensured, the production operating cost is reduced, the energy is saved, the enterprise management is enhanced, the production efficiency is improved, and the enterprise performance maximization is facilitated.

Description

technical field [0001] The invention belongs to the technical field of intelligent control and scheduling in iron and steel smelting, and in particular relates to an intelligent scheduling method for steelmaking production process. Background technique [0002] During the steelmaking process, materials are transferred between processes, and the upstream and downstream processes in the same operation span are connected by crane transportation; for the processes in different spans, the connection is mainly achieved by trolley transportation; the transported materials include scrap steel, Molten iron, molten steel, auxiliary materials and containers, etc. The smooth material transportation in the whole process from the molten iron entering the steelmaking workshop to the molten steel pouring into the continuous casting machine is the cornerstone to ensure the normal operation of the steelmaking process. Reasonable operation planning and plan rearrangement under unexpected circ...

AI Technical Summary

Problems solved by technology

Reasonable operation planning and plan rearrangement under unexpected circumstances are important guarantees for the precise connection and orderly operation of each process in the steelmaking process, and are of great importance to balanced production, energy saving and consumption reduction, production and operation cost savings, and improvement of production efficiency and corporate competitiveness. Significance, at present, the production management technology and means of most steelmaking production processes in my country are still backward, and the level of informatization lags behind the related industries in developed economies. method and system
