Research On Iron And Steel Scrap Steelmakkig-Continuous Casting Scheduling Problem Aiming At Energy Saving And Carbon Emissions Reducing

With the speeding up of social development, the problem of climate, resource consumption and environment pollution problem has becoming a very serious problem facing the world. Energy conservation and emissions reduction is measure must be taken by each industrial enterprise, as the key industries of iron and steel industry, energy saving and emission reduction will no doubts be a main role. Steelmaking continuous casting is the core content of iron and steel production, so the optimization scheduling for steelmaking-continuous casting of the iron and steel scrap for steel enterprise energy conservation and emissions reduction has great importance.Now researches for steelmaking-continuous casting production scheduling problem in iron and steel enterprises focus on a variety of basic algorithm in the optimization of production scheduling, the iron and steel scrap iron and steel scrap to save energy in the process of steelmaking continuous casting production scheduling problem rarely been studied, and most studies regared the smallest and largest output of total completion time as the optimized target, although there are considering the energy consumption, but not completely with the goal of energy conservation and emissions reduction.At present, the capacity is not the bottleneck. In this paper, besides considering the maximum completion time, the carbon emissions closely related to the environment are considered. For steelmaking-continuous casting production carbon emissions in iron and steel scrap is analyzed in detail,divides into the composition of carbon emissions of carbon emissions and furnace process clearance idling of carbon emissions. With carbon emissions constraints is established to minimize the maximum completion time as the optimization goal of waiting time for steelmaking-continuous casting production scheduling model, limited research on carbon emissions constraints on the influence of carbon in iron and steel enterprises, and limited waiting time of equipment idle time and idling of the carbon emissions generated by the impact. Then established in carbon dioxide emissions by minimizing the optimization goal for steelmaking-continuous casting production scheduling model of iron and steel scrap, and designs genetic algorithm for solving, to make it and minimize the maximum completion time for the target of production scheduling results are compared, combined with the simulation analysis shows that algorithm is very effective. Whether the carbon emissions as for steelmaking-continuous casting production scheduling constraints in the process of iron and steel scrap, or to minimize emissions of carbon dioxide as the optimization goal, all for steelmaking-continuous casting production scheduling problem in the traditional on the basis of fully considering the problem of carbon emissions, for energy conservation and emissions reduction measures of the implementation of the iron and steel enterprise has great reference value and guiding significance.
