A modern view on carbon transfer into blast furnace hot metal and empirical equations for saturated carbon content are presented. Carbon saturation depends on furnace gas composition, temperature, pressure and flow, burden and coke properties, and the thermal state of the furnace. The deposition of sooty carbon in the furnace is explained and quantified. Practical applications for the use of hot metal’s carbon subsaturation degree in study of coke properties, evaluation of deadman status and hearth thermal state control are discussed.
