Example Embodiment

[0030] The technical solutions of the present invention will be further described below in conjunction with the drawings and specific implementations.

[0031] Such as figure 1 , figure 2 As shown, a dynamic scheduling method for steelmaking operation planning, the method mainly includes the following steps:

[0032] Step 1. Tundish plan layout. According to the production order from the steel mill and / or the slab rolling plan that needs to be hot loaded and sent from the hot rolling mill, the steel mill tundish plan is compiled. The specific steps are as follows:

[0033] 101) Order preprocessing: According to the steel grade, specification, and output information of the customer order, it is matched with the current inventory to calculate the number of slabs to be smelted; secondly, the customer order is divided into multiple small orders according to product information. The order corresponds to a steel grade and slab specification.

[0034] 102) Order grouping, grouping multiple ...

Abstract

The invention discloses a dynamic scheduling method of a steelmaking operation plan. The method mainly comprises the following steps: 1) carrying out tundish plan scheduling, and making a steel mill tundish plan according to a production order of a steel mill or a rolling plan of slabs which need to be subjected to hot charging and hot transfer, wherein the rolling plan is transmitted from a hot rolling factory; 2) making a continuous casting machine operation plan, receiving the tundish plan and site actual performance feedback, generating the continuous casting machine operation plan, and re-adjusting the plan according to production time data, wherein the step of making the continuous casting machine operation plan mainly comprises the following substeps of making cast time, sorting heat in the cast and making heat time; and 3) making a smelting operation plan, and realizing the making of the smelting operation plan according to the continuous casting machine operation plan, and re-adjusting the plan according to practical production working conditions. The dynamic scheduling method guarantees production safety, lowers production and operation cost, saves energy, enhances enterprise management, improves production efficiency and accelerates enterprise benefits to be maximized.

Description

technical field [0001] The invention belongs to the technical field of intelligent control and scheduling of iron and steel smelting, and in particular relates to a dynamic scheduling method for steelmaking operation planning. 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 circumsta...
