Research On Optimized Problems Of Production Scheduling Planning In Steelmaking & Continuous Casting

Iron and steel industry is the pillar industry in China. With an increasingly competitive domestic and international steel industry, the use of modern management system, the use of advanced production technology and techniques, on-time delivery and provide quality service to become a business development direction. In the iron and steel production, steelmaking- continuous casting steel production system a key link in the iron and steel integrated production systems, quality production plans and scientific production scheduling is an important guarantee for the smooth integration of production of steel, and therefore Study steelmaking- Continuous Casting Production Scheduling program to rationalize the process to shorten the production cycle, improve enterprise management level and economic benefits is important.Steelmaking- Continuous Casting Production Scheduling programs include contract plans, batch planning, job scheduling, which plans to include a contract year contract plan, contract month plan, contract day program, batch programs include heats Cast plan and plan, job scheduling schedule each process time for each device.Preparation of high-quality steel- Continuous Casting Production Scheduling program is the goal of the iron and steel in integrated steel production. Using reasonable production plan can make steel, refining and casting process can be a good convergence, full use of equipment resources, reduce the temperature drop and other reasons produce a surcharge. So as to save resources, reduce production costs and shorten the production cycle, reduce inventory and improve product quality goals.This paper studies the content and results of the work:1 Read a lot at home and abroad for Steelmaking- Continuous Casting Production Scheduling literature program, according to Chengde Steel Plant Steelmaking- Continuous Casting actual production, presentation Steelmaking-Continuous Casting Production processes, production scheduling planning processes, production scheduling preparation strategy.2 Iron and steel enterprises based on the actual production process and constraints of steelmaking- continuous casting batch planning model, and by genetic algorithm, genetic algorithm uses natural number coding, which heats plan solved by improved adaptive genetic algorithm to improve the efficiency of the algorithm.3 According to the results of batch planning, preparation of job scheduling, job scheduling using the first row caster plan, based on heuristic rule thrust reversers refining, steelmaking plan. Caster planning problem using improved genetic algorithm, heuristic algorithms child schedule drawn, crude scheduling optimization linear programming algorithm simplex method.4 The simulation uses Chengde Iron and Steel Plant 1780 hot rolled coil mill production data and production model simulation, simulation results verify the correctness and feasibility of the full text of the design.5 By contrast with the actual labor programming, programming is superior to artificial programming article, the paper work has practical value.
