Abstract

Abstract—The distribution of the gas flow rates over the blast-furnace height is studied. The best blast-furnace gas dynamics is determined by the range of gas-flow rates in the batch column—in particular, at the tuyere exit and in the batch-free charging zone. The velocity of the blast and the blast-furnace gas may be used to assess the stability and optimality of the gas-dynamic conditions in smelting.
