FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy and can be used in metal casting. Proposed plant comprises ladle with bottom provided with inner barrel with outlet communicated with through hole of gate top plate equipped with connecting device of protective pipe for ladle with its outlet. Protective pipe is made with possibility of connection and disconnection from sliding frame installed in T-shaped passage of support frame, and with possibility of back and forward movement along transverse axis by means of hydraulic lever. Extendable frame is intended for alternate bringing of channel of protective pipe of ladle into combined and non-aligned position with hole of lower plate of gate at movement of support frame through T-shaped passage. When the channel of the protective pipe of the ladle is matched with the hole of the lower plate of the block, the pushers are pressed on the underlying surface of the protective tube of the bucket.
