Abstract
A process for estimating a particle size segregation in a burden layer at a blast furnace top is disclosed, which comprises measuring a particle size distribution of a burden material before the charging and a layer thickness distribution of the burden layer after the charging, and estimating a particle size distribution at every position in the burden layer charged at the furnace top on the basis of the above measured values, charging conditions and furnace operating conditions according to a simulation model of particle size segregation.
