A novel and efficient method is proposed to agitate a molten steel bath. A water model study is carried out to understand the mixing characteristic of the bath. A water jet is generated with a J-shaped lance in a cylindrical bath. The lance exit made of glass pipe is sharpened to form a single-hole nozzle and the nozzle is placed on the centerline of the bath. Mixing time in the bath is measured with an electric conductivity sensor. An empirical equation is proposed for correlating the measured values of the mixing time as a function of the water flow rate, vessel diameter, and so on.
