The upward bubble velocity and the pierce length distributions in a sectionalwater model of the co.per co.verter in Guixi Smelter in Jiangxi, china, were measured using atwo-co.tact electro-resistivity probe. In the case of using a single tuyere, the bubble velocitydistribution along longitudinal direction was similar to that derived from Guassian function. Beyondthe center of the longitudinal range, the bubble pierce length exhibited a sudden increase. Theupward bubble velocity at a specified location co.ld go up to meters per seco.d. Its probability ata fixed location obeys a lognormal function; the bubble pierce length there varies bellow a fewcentimeters. In the case of using multi-tuyeres, the upward bubble velocity was roughly uniformright above the tuyeres and showed a slow decrease beyond this region. The bubble pierce lengthwithin both of these two regions was roughly uniform. Its average value in the former region,however, was found to he somewhat lower than that in the later.

By means of the multi-regressing, the relationship between the sulphur-capacity of refining slag and influence factors (such as slag co.ponents, temperature) has been established for CaO-SiO_2-Al_2O_3-MgO slag-system. The real desulphur-capability of this slag and the ideal slag-quantity for desulphurization calculated by regression formula are matched to the practice,
