Analysis of the Blast-Furnace Process at High Smelting Rate

Abstract

The influence of the smelting rate, which is estimated from the specific productivity of a blast furnace, on the stability of its operation is analyzed. The influence of the smelting rate on the reduction conditions of wustite in the zone of indirect reduction is studied. It is shown that the higher the smelting rate, the weaker its effect on the utilization of CO. The stabilization of the processes in the wustite reduction zone is accompanied by less fluctuations of the composition of products. This is in agreement with industrial data.
