FIELD: metallurgy.
SUBSTANCE: proposed device comprises horizontal built-up crystalliser with a hole in its top part, a pair of sidewalls, top and bottom walls. Wedge recesses are made on calibrating sections of sidewalls and arranged in symmetry about crystalliser crosswise plane of symmetry and at the distance from it making 0.3-0.4 of sidewall total length. Wedge formed by solidified metal in said recesses prevents back slippage of billet when crystalliser walls move.
EFFECT: higher efficiency and reliability.
