Abstract

The  features of  ladle   processing for  various steels, the low-carbon, desulphurized and resulphurized steels including, are  regarded in the  article as well as the  various variants for minimization of the non-metallic inclusions content in these products. The purity of steel can  be controlled by the  improvement for the  technology of metal tapping from the  steel-teeming ladle, by the  adjusting of the  processing time for the metal bath in the ladle, by the adding of various alloying agents, as well as by the  soft bubbling and  adding calcium in the  liquid  steel. The presence of both  the  melt steel-dissolved calcium and  the  metal impurities modified by the calcium additions inhibit the depositions formations. Upon  that, the  purpose which  is posed while  the  ladle  processing is not so much  the inclusions content minimization, but rather the inclusions content optimization. Ill. 8. Ref. 7.
