FIELD: metallurgy. SUBSTANCE: plant has two rolls rotating in opposite directions and cooled from inside, two side walls of ceiling and aids to keep and press walls of ceiling against butts of rolls with some force. Plant is fitted with pushing plate having capability to move in direction of longitudinal axes of rolls and arranged perpendicular to this direction and panel that supports walls of ceiling positioned on pushing plate in opposition to the latter. Plant includes at least three pushing members of spring type inserted between pushing plate and panel. These pushing members are distributed in zone which shape corresponds to form of wall of ceiling and can act on this wall with pushing forces independent of each other. EFFECT: keeping of leak-tightness between side wall of ceiling and butts of two rolls against which this wall fits over entire technological process of casting. 7 cl
