Abstract

A water model experiment was conducted in order to identify the factors that would improve the surface reaction during secondary steelmaking. We examined the controlling factors of the surface reaction and evaluated the surface reaction rate. The conclusions are summarized as follows. 1) The surface reaction rate increased with the gas bubbling rate and the plume eye area, thereby decreasing the thickness of the top layer. 2) Empirical equations were obtained for the surface reaction rate at the plume eye area and at the outer area of the plume eye. In addition, empirical equations for the plume eye area and bubble rising velocity were obtained.
