Beschreibung
Zusammenfassung:	FIELD: metallurgy. ^ SUBSTANCE: invention concerns ferrous metallurgy. Particularly it concerns basic oxygen process. Method includes reservation in unit of final slag and its blowing by nitrogen. Simultaneously there are fed materials increasing lining fireproof characteristics, in gas-bearer current by separate route in ratio (10-25):1 by mass. ^ EFFECT: increasing of vessel lining steadfastness. ^ 1 tbl, 1 ex
