Abstract

PURPOSE: To carry out the operation for blowing-in nitrogen gas without installing the blower for raising the pressure separately, by introducing nitrogen gas of low oxygen content from the oxygen generating apparatus to the blast pipe connected to the inlet of the blower for raising the pressure for the blast furnace, at the operation of the blast furnace in the reduced production, etc.
