Hydraulic Model Experimental Study on Coherent Jet Flow Field
Based on Anshan Iron and Steel Company 180t top-bottom converter prototype, the operating parameters and the structural parameters for best stirring effect of bottom-blowing converter and top-bottom converter was given by the hydraulic model test in this article. Coherent jet oxygen lance converter smelting effect was simulated under the condition of keeping the best top blowing gas flow rate. The experiment result shows that coherent jet oxygen lance may achieve the result of top-bottom converter stirring effect. If coherent jet oxygen lance could be applied in the converter, bottom blowing system of converter could be canceled. In that case, not only the converter equipment can be simplified, but also the converter lining life can be improved, bring steel-making technology transformation.
