description It was studied in the article the possibility of intensification of removal of non-metallic inclusions in a teeming ladle during holding without any additional external influences on the metal (argon blowing or electromagnetic stirring). Increasing the efficiency of removal of non-metallic inclusions is achieved by creating in a teeming ladle during tapping a circulation pattern that accelerate the floating of inclusions. The described effect is achieved by using a rational shape of the workspace of the teeming ladle, which has been found as a result of “water” modelling. To carry out the experiment, the authors have proposed the similarity numbers describing the floating of non-metallic inclusions in the ladle during the tapping and for some time after its completion. On the basis of the proposed similarity numbers, an experimental facility and the experimental method were developed. In the course of the experiment, the construction of linings of several types was studied. Ladles of the best design provide by 16–19 % faster removal of non-metallic inclusions from steel than in ladles of conventional design. The results of the research can be useful for mini-plants and enterprises with ladles of small capacity, where the use of argon blowing and electromagnetic stirring is technologically and economically unreasonable.
