HRCEA (hybrid of rules and compression-extensive algorithm)-based steel making-continuous casting production scheduling method for special steel mill

Abstract

The invention provides a HRCEA (hybrid of rules and compression-extensive algorithm)-based steel making-continuous casting production scheduling method for a special steel mill. In the scheduling method, model and algorithm parameters are obtained by analyzing a steel making-continuous casting production flow; according to a known production casting times plan, an initial production scheduling plan is worked out by adopting the HRCEA; and all subsequent furnace working plans are adjusted by using the HRCEA according to an established scheduling rule and fed-back real-time data so as to realize dynamic scheduling. According to the HRCEA-based steel making-continuous casting production scheduling method disclosed by the invention, with the aims of reasonably quickening production rhythms and shortening production process time, equipment conditions of the steel mill, produced steel grades and temperature requirements of the produced steel grades are considered; an executable production scheduling plan can be quickly worked out, thus schedulers are facilitated on adjusting the scheduling plan in real time; and the production scheduling of the steel making-continuous casting process is optimized.

Description

technical field [0001] The invention belongs to the field of steelmaking-continuous casting production planning and scheduling, and in particular relates to a HRCEA-based steelmaking-continuous casting production scheduling method for special steel mills. Background technique [0002] The steelmaking-continuous casting section plays an important role in the production process of special steel. The molten iron passes through the steelmaking furnace, refining device, and continuous casting machine to become a billet. The production process of special steel has the characteristics of many equipments, many modes, many routes and many disturbances. Steelmaking-continuous casting production scheduling refers to determining the starting time of each pouring plan in the corresponding continuous casting machine and the start and end time of each furnace plan in the corresponding equipment according to the production plan, that is, the production scheduling plan; at the same time, the...
