Zusammenfassung:	The invention relates to a sleeve for blowing solid materials into molten metal baths, specifically molten steel baths, through the wall of a ladle containing the molten metal bath. To improve the characteristics of such a sleeve, the invention proposes that a forward sleeve section, facing the molten metal bath, be made of an insulating material with lower thermal conductivity than that of the material of the middle and rear sleeve section.
