Steelmaking-continuous casting-hot rolling integrated scheduling method and system

Abstract

The invention provides a steelmaking-continuous casting-hot rolling integrated scheduling method and system. The method comprises the steps of S1, performing initialization to obtain a steelmaking-continuous casting scheduling plan; S2, obtaining a hot rolling scheduling plan according to the current steelmaking-continuous casting scheduling plan as well as a working order demand, a production line model, a current production rhythm, a rolling unit length constraint, and a rolling unit internal adjacent plate blank width, thickness and hardness jump constraint; S3, determining whether an inventory change situation meets a preset inventory optimization plan or not according to the current steelmaking-continuous casting scheduling plan and the hot rolling scheduling plan, and if the preset rule is met, entering the next step, otherwise, adjusting current parameters related to inventory optimization and returning to the step S1; S4, obtaining overall heat supply rate data according to the current steelmaking-continuous casting scheduling plan and the hot rolling scheduling plan; S5, judging whether an integrated scheduling stop condition is met or not, and if the stop condition is met, performing the scheduling plan, otherwise, performing the next step; and S6, performing re-optimization to generate the steelmaking-continuous casting scheduling plan, and returning to the step S2.

Description

technical field [0001] The invention relates to the technical field of industrial process optimization information dispatching, in particular to a steelmaking-continuous casting-hot rolling integrated dispatching method and system. Background technique [0002] The development trend of the modern iron and steel industry is large-scale equipment, continuous production process, high-speed and automation; at the same time, with the intensification of industry competition, it is urgently required that steel plants can organize production flexibly to meet the needs of the market in a timely manner with small batches and multiple varieties. , high-quality, low-price market demand. In recent years, the three processes of continuous casting billet hot delivery, hot charging and direct rolling have emerged around energy saving, directly connecting the processes of steelmaking, continuous casting and hot rolling, making the production of iron and steel enterprises an integrated organi...
