Abstract
It is known that an increased FeO content reduces the start melting temperature of the primary slag, which prevents the formation of a stable skull, thereby increasing the thermal load on the refrigerators of bally and bosh, and it is accompanied by increased heat losses. FeO content in the raw slag was determined by the development of indirect reduction reactions. The aim of the experiment was to evaluate the ways to reduce the heat losses of refrigerators of bally and bosh. Reducing the gas temperature in the peripheral zone of the furnace is accompanied by a change in the degree of indirect restoration. This fact can be considered as an indicator of the temperature of the periphery of the indirect restoration. The developed model for calculating the gas temperature and reducing its operation in the peripheral zone of the blast furnace can be used to optimize the thermal state of the furnace shaft in its peripheral zone.
