In this process, the oxygen efficiency for desiliconization, as defined by Equation (1.3.52), decreases with decreasing silicon content because the stirring energy is limited. When the oxygen efficiency for desiliconization decreases, severe slag foaming occurs as the FeO content in the slag and the formation of CO gas increase.
