Embodiment Construction

[0117] The embodiment of the present invention is a steelmaking plant of a large steel enterprise. The steelmaking plant has two converters, one RH refining furnace, and two continuous casters. The daily production capacity of the converter is about 65 furnaces and the daily production capacity of RH refining is about 30 furnaces. The smelting capacity of the converter is 300 tons. The width adjustment rule of the continuous casting machine is positive "Y" width adjustment (that is, from wide to narrow). The width adjustment range is 50mm and 100mm each time. Allow to adjust the width once, the maximum (small) setting width of the continuous caster is 1450mm (900MM). The slab produced by continuous casting is then sent to the hot rolling workshop to be rolled into coils. The side pressure of the slabs according to different hardness groups is [50mm, 250mm].

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 steel production technology and automation, and relates to operations research modeling and intelligent optimization algorithms, in particular to a method and system for automatically preparing a steelmaking-continuous casting furnace batch plan. Background technique [0002] 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, and cold rolling area. Among them, the production processes involved in the steel zone are mainly steelmaking, refining, continuous casting, die casting, etc. The semi-finished products-slabs (or steel ingots) produced are the raw materials for various final steel products. Therefore, the processes involved in the steel zone often b...
