Abstract: The paper presents a brief introduction about the significant work conducted with a scale of physical bell-less burden model for falling curves and burden distribution at any given chute angles. An incidence formula between flow control gate (FCG) and burden flow was established by the actual measurement of charging. The measurement of falling curves using laser trajectory probe at given stockline and any given chute angles was calibrated with the actual measurement data. Based on the above, a burden distribution mathematical model was created in AnSteel. This mathematical model could calculate burden distribution profile and help BF improve operation on thickness of layers, profile and ore/coke distribution on diameter direction. Key words: Bell-less top, Mathematical model, Burden distribution profile
