It is important to control the burden distribution, which affects the gas flow pattern in the blast furnace. Therefore, a burden distribution analysis model is needed to predict the burden profile. In this study, the burden descent and gas flow models were developed to complete a blast furnace analysis model. A previous study reported two models based on the burden trajectory and stock model. The burden profile that is due to the burden trajectory was calculated using stock model in the upper part of shaft. The entire burden profile, which is classified into five burden types calculated using the descent model, was used for a gas flow calculation as the initial conditions in the gas flow model. The analysis models were developed using a visual basic based spread sheet, and compared with the 1/12 scaled model experiment. In addition, a GUI (Graphic User Interface) was added for the convenience of the operators.
