A slab re-cutting device comprises: a roll moving a slab produced by a continuous casting device; a heat protection cover cutting off the heat generated by the transfer of the roll; a torch(5) cutting the slab; a running unit(1) moving the torch to the width direction of the slab; a traverse motion unit(2) moving the running unit to the longitudinal direction of the slab; and a pendant box(8) having a switch controlling the operation of the running unit and the traverse motion unit.
