SUMMARY:Novel numerical approach for sintered iron ore plastic deformation phenomena
DESCRIPTION:A numerical model of sintered iron ore deformation during ironmaking blast furnace processes helps to achieve superior process operations, particularly with the current goal of decarbonization. In this study, the high-temperature softening behavior of sintered iron ore characterized by a low-melting-point molten slag core and solid iron-rich phase shell structure was modeled using the Bingham plastic fluid model with an additional structural force that expresses the stiffness. The shape matching (SM) method was incorporated into the framework of the smoothed particle hydrodynamics (SPH) method, the stiffness parameter in the SM scheme was varied, and consistency with experimentally observed results was confirmed. The model was verified by comparing the simulated and experimentally determined 3D shape of sintered ore particles with different reduction rates after heating to various temperatures from 1473 to 1673 K. Furthermore, case studies simulating the softening and melting of the sintered ore particle bed in the cohesive zone were performed. We can expand this model's applicable range by experimental investigation of the effect of the composition of various types of ores on deformation behavior, and the mixing effect of various ores on bed deformation behavior could be clarified in detail.
