STABILIZING CHARGE MATERIALS DISTRIBUTION IN BLAST-FURNACE THROAT

Disturbances in the stability of charge materials distribution in blas t furnaces due to effects produced by the energy of the filling gas in the interbell space are considered, and relevant operating data on tw o blast furnaces are analysed. The introduction of blast furnace opera ting technology with a new gas seal design enables distribution to be stabilised with a corresponding improvement in the technical and econo mic operating indices and in hot metal quality. Interest in the techno logy, including from abroad, suggests that it could be widely applied.
