Abstract
Circulation rate of melt, one of the important factors which determine decarburization rates of RH system, was calculated by a 3-dimensional numerical simulation technique. A new model for analytic calculation of the shape and volume of plume zone formed by side blowing of Ar gas was designed to obtain the driving force of melt circulation. Circulation flow rates were measured in the 1/10 scale water model and in an actual RH operation to verify the calculated results. The predicted circulation rates showed a good agreement with both experimental results, Because the new program can calculate the circulation rate with various operating conditions and dimensions of RH system, it could be very helpful to determine the optimum operating conditions and to design new RH systems.
