Abstract:According to similarity theory,the effects of process parameters on refining mixing time has been studied including gas blowing rate,gas blowing position by 1:4 water model simulated for an 80t Single Snorkel Refining Furnace. On the basis of water model,the analysis of gas blowing rate, gas blowing position on the single snorkel refining furnace flow field has done by simulation calculation. The results of mathematical calculation agree well with the experimental data. Results show that the appropriate scope of gas blowing rate and gas blowing position contribute to decreasing the mixing time. Under this experimental conditions, the gas flow rate is 6 Nl/min, and blowing air is r/R=0. 5.
