Design And Implementation Of TISCO The Scheduling Management System For Hot Strip Mill Hot-rolling

Hot rolling production scheduling needs to consider not only materials circulation and resource balance,but also time and energy balance under the production circumstance of high temperature. Since1980s,hot rolling production scheduling is studied and applied by overseas large iron and steel plant to save energy resources and reduce wastage,and hot rolling production planning and scheduling become problems urgent to be solved.This dissertation has studied production planning of hot rolling and slab yard, hot rolling production planning system.Now,hot rolling plant faces various market demands such as large variety,small quantity, low price,high quality, rigorous consignment date etc.,this dissertation suggests a production planning model of hot rolling based on the Just-In-Time idea.The model considers not oray the slabs’bounce on gauge and hardness, obverse and inverse bounce on width, and the rolling length constraint ofthe slabs witll same width, but also the reasonable arranging of warm-up materials and staple materials, and it cart prudece whole roll plans which are "tortoise shell" shape and meet with the hot roiling rules.Considering operation flow of slab entering slab-yard, the slab location decision are suggested.Using the object-oriented programming design method, hot Strip mill of TISCO production planing management system is designed and carried out, which is enhancing work efficiency for planer,and reducing operational and management costs.
