Abstract:In order to improve the pellets charging ratio in blast furnace, reduce the energy consumption in iron and steel production process and alleviate the increasingly severe environmental protection situation, based on the basic roasting theory of oxidized pellets, the features of magnesia-bearing fluxed pellets are analyzed and combed combined with the relevant academic research results. On the basis of this, the thermal parameter of magnesia-bearing fluxed pellets prepared by the travelling grate process is studied. The results show that the pellet proportion in the blast furnace material structure can be increased greatly due to the good technical and economic index magnesia-bearing fluxed pellets. Through the computational fluid dynamics (CFD) numerical simulation and calculation of material flow and energy flow models, the thermal parameter of the existing travelling grate process is analyzed, the characteristics of magnesia-bearing fluxed pellets production are expounded, and the advantages of travelling grate in the magnesia-bearing fluxed pellets production are discussed.
