Embodiment Construction

[0034] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0035] Such as figure 1 As shown, a steelmaking production process intelligent scheduling method, the scheduling method mainly includes the following steps:

[0036] 1) Obtain a production order, which includes the order number; the length, height, thickness, density and weight requirements of the slab specification; the steel type and steel grade to be produced; the planned start time and the planned delivery time;

[0037] 2) Pre-process the order according to the slab output, specification, delivery date, steel grade and steel type;

[0038] 3) Tundish plan arrangement, determine the tundish sequence, the number of continuous pouring furnaces and pouring number and other information;

[0039] 4) Arranging the operation plan of the continuous casting machine, and determining the planned starting...

Abstract

The invention discloses an intelligent scheduling method for the steelmaking production process. The scheduling method mainly includes the following steps: 1) inputting the production plan, the production plan includes: the production order and the hot delivery and hot loading rolling plan given by the hot rolling workshop ; 2) Decompose the operation plan, calculate the number of slabs, decompose the order according to the steel type, slab specification, and delivery date; Sorting; 4) Acquisition of characteristic signals, obtaining characteristic signals of key positions of underlying equipment through corresponding sensors; 5) Execution of crane optimization algorithm; Displayed to the scheduler in the form of a Gantt chart. The invention ensures production safety in the steelmaking process, reduces production and operation costs, saves energy, enhances enterprise management, improves production efficiency, and is beneficial to promoting enterprise benefit maximization.

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...
