Abstract: In order to decrease magnesium vapor bubble diameter in desulphurization of hot metal and to improve desulphurization efficiency, the effects of the equipment parameters and operating conditions on average bubble diameter were studied by a water model based experiment. The bubble dispersions under different experimental conditions were collected by a high-speed camera. The image analysis software was used to obtain the average bubble diameter under different experimental conditions and the major factors were analyzed by a water model based experiment. A relationship between the average bubble diameter and the major influencing factors was established, according to the homogeneous principle and Buckingham’s theorem. The relationship between the average bubble diameter and the experimental conditions can be obtained by fitting the related parameters with experimental data.

Key words: desulfurization, hot metal, average bubble diameter, dimensional analysis, image processing
