Abstract (Figure 1) Process for introducing additive substances which are capable of flow into a metallurgical vessel and a vessel for that process For the metallurgical treatment of a molten metal bath (1) in a metallurgical smelting and refining vessel (3), additive substances (43) which are capable of flow, in particular lime, are supplied in a granular to dust state, at least during a part of the refining phase, to the upper region of the inward side (15') of the vessel wall (11), distributed around the periphery thereof. At the vessel wall (11) the additive substances (43) form a barrier or protective layer which reduces the energy losses and increases the service life of the vessel (3).
