SUMMARY:Simulation of burden charging in a blast furnace equipped with a bell-less top system using Discrete Element method
DESCRIPTION:In the BLT systems, metallic and coke raw materials are discharging in layers into the blast furnace. The quantification of granular materials characteristics into the blast furnace, such as granulometric segregation and components distribution are difficult to perform. Therefore, this work consists in the development of a predictive model for the understanding and optimization of the blast furnace burden distribution equipped with a BLT (Bell less Top) based on calibrated high-fidelity DEM simulations, which were used as a viable and less expensive alternative compared to full scale experiments. To perform the simulations of the blast furnace charging, calibrations of contact parameters for coke and sinter were done, additionally the calibrations of pellets and lump ore parameters available in the literature. The present work contemplates the construction of a realistic virtual model of the blast furnace installed in Rio de Janeiro. Particles size distribution close to real materials were adopted in the simulations. The DEM simulations results allowed for the improvement of a phenomenological burden distribution model based on Park et al. (2011). The model was based on three charging strategies and four strategies for the discharge of the BLT hoppers and was able to predict and to determine the burden profile obtained in DEM simulations when compared to the original model by Park et al. (2011).
