| description | Under the overall requirements of China’s implementation of the “Dual Carbon” strategy and green manufacturing, the iron and steel industry will face severe challenges from carbon emission reduction in addition to costs. Pellet’s substitution of sintering is an important measure to effectively reduce the waste gas pollution load of pre-ironmaking, reduce energy consumption and carbon emission reduction, and is an important way for iron and steel industry to move towards green manufacturing. The cost reduction proposed in this paper is not limited to considering the intermediate processes such as procurement, sintering and pelletizing, but the overall consideration of the whole process from raw material procurement to blast furnace production. With the maximum molten iron profit as the objective function, the key factors such as ore inventory, sinter, pellets, molten iron and slag are comprehensively considered, and the mechanism model is established according to the comprehensive consideration of material flow, energy flow and information flow. Through the support of the system, it not only improves the pig iron profit, improves the metallurgical performance of the burden structure and slag performance, and promotes the smooth running of the blast furnace, but also reduces the market risk caused by the concentrate and lump ore inventory in the current period. |
