Abstract

Accretion on the lining of the blast furnace results in a harmful effect on burdendescent, which also has a negative effect on energy balance. This eventually leads toincreased CO2emission. We examined which blast furnace zones were significantly affected by thethickness of the accretion layer and how this affects the blast furnace gas streamrelations. Using a heat transfer model, the samples taken from the accretion andstatistical analysis of the typical operating parameters of the blast furnace, amathematical model was created in order to determine the thickness of blast furnace shaftaccretion and its effect on gas utilization.
