Abstract
A reliable simulation model of burden distribution in blast furnace was developed. This model has the following features:
(1) A wide range of burden mixtures of sinter and pellets may be given.
(2) A variety of charging conditions such as coke base, ore/coke, several combinations of coke and ore batches, movable armor settings, and a stock line may be given.
(3) Burden profiles will be reproduced with an exellent similarity by use of classification of burden profiles into five patterns.
(4) The influence of burden bed profiles prior to charging on burden distribution is taken into account.
(5) The reduction of surface angle with the increase of gas flow rate, and/or with the descent of burden in stack is taken into account.
