Abstract

Abstract: Water model study of oxygen bottom blowing converter for matte smelting was carried out， and the effects of main factors such as nozzle numbers， angles， diameters and the gas velocity on the mean bubble diameter， gas holdup and liquid splashing were investigated. The results show that largediameter nozzle increases the mean bubble diameter， and leads to splashing with serious slag entrapment. The increase of inclination angle of nozzles weakens the splashing in the bath and decreases the gas holdup. Larger gas velocity has advantage for bubbles dispersion and disintegration， but the splashing gets more serious. Compared with single nozzle， the performance of double nozzle is better， and its splashing is weaker. When the angle between two nozzles is 44°， the gas holdup reaches its maximum of 9%.

Key words: water model, bottom blowing, matte smelting, jet flow, gas holdup, bubble dispersion and disintegration
