Water Model Study on Circulation Rate Influenced by Snorkel, Nozzle and Blowing Parameters in RH Refining
Abstract:
A water model of 1/4 linear scale for 210t RH has been established. RH circulation flow rate is measured by a velocimeter. The influences of lifting gas flow rate, snorkel inner diameter, injection depth and nozzle inner diameter on circulation rate were discussed. The dimension correlation has been calculated for the prediction of circulation rate. The results showed that the formula of circulation rate is 5.434×10-6G0.356·D1.254·d -0.106·H 0.821. The best nozzles inner diameter in terms of circulation rate was 3mm.
