Abstract

The invention relates to an automatic planning method of a steelmaking and continuous casting heat batch plan and a system thereof, belonging to the IT field and including the following steps: 1, data collection; 2, construction of model; 3, optimization solution; 4, outcome assessment; 5, human-computer interaction; 6, sending down for executing. All indexes of the heat batch plan result obtained by adopting mathematical model and optimization algorithm of the invention are superior to that of the heat batch plan result obtained by the existing on-site manual planning pattern, in addition, the planning time (about 5 minutes) of the automatic planning method of the invention is far shorter than the planning time (about 2-3 hours) of the manual planning pattern. Therefore, the automatic planning method of the invention improves the scientificity of the traditional manual planning pattern, enhances planning level and quality, solves the problem of low efficiency in the manual planning pattern, and provides a scientific method for planning the on-line heat batch plan on a computer integrated manufacturing system in a steel enterprise.

Description

technical field

[0001] The invention belongs to the technical field of iron and steel production technology and automation, relates to operations research modeling and intelligent optimization algorithms, and in particular to a steelmaking-continuous casting furnace batch plan automatic preparation method and system. Background technique

[0002] Iron and steel production needs to go through a series of processing stages from the input of iron ore raw materials to the output of steel products. According to the technological characteristics of the production process, its production can be divided into the following areas: iron area, steel area, hot rolling area, cold rolling area. Among them, the production processes involved in the steel area are mainly steelmaking, refining, continuous casting, die casting, etc., and the semi-finished products produced by it - slabs (or steel ingots) are the raw materials for various final steel products. Therefore, the processes involved ...
