FIELD: ferrous metallurgy; open-hearth furnaces equipped with detachable swinging spouts for tapping melt in two ladles. SUBSTANCE: hearth steel-making unit has detachable spout engageable with tapping hole 3 of furnace and shorter intermediate spout 4 secured on tapping plate 3. Intake portion of detachable spout is made in its pipe 6 whose longitudinal axis lies in one vertical plane with longitudinal axis of spout 4. Angle between longitudinal axis of lateral pipe 7 and pipe 6 depends on position of ladles under definite conditions. Swinging of detachable spout in course of tapping is effected by means of jib crane. Pipe 6 turns on horizontal axle 8. Such swinging mechanism provides for adjustment of melt distribution in flows at minimum deviation of jet from plane of tapping. EFFECT: enhanced uniformity of filling the ladles and avoidance of splashing. 2 dwg
