Abrégé

The invention relates to a flame cutting unit (1) for cast workpieces in a continuous casting system having a conveyor belt (4), on which a cast strand (2) to be severed by flame cutters into workpieces is guided transversely to the transport direction. The flame cutting unit (1) comprises a bridge (5) traversing the conveyor belt (4) and having an electric station (8), a gas control unit (7), an arm (12) disposed movably on the bridge (5) and equipped with a flame cutter (14) and an arm drive (11). The arm (12) is disposed over the cast strand (2) centrally in the longitudinal direction thereof and can be moved out of the bridge (5) and into the same in synchronous operation with the cast strand (2) into the bridge (5). The synchronous operation is carried out by detecting the speed of the cast strand using a measuring device (18) and by subsequently synchronizing the arm drive (11). The flame cutter (14) is disposed at the front end of the arm (12) and can be moved transversely over the cast strand (2) to be severed by a rotatably supported shaft (16) in an oscillating motion about the longitudinal axis of the arm (12).

Abrégé

The invention relates to a torch cutting unit (1) for torch cutting cast cold and hot billets, ingots and slabs from steel in and after continuous steel casting units, having a crane tower (2) and a boom (4) aligned transversely to the casting strand direction, whereon one or two torch carriages (5) with cutting torches (6) can be transversely displaced to the casting strand (3). The crane tower (2) is disposed stationary next to the casting strand (3) and comprises an articulated arm (13) that can be pivoted horizontally within a predetermined angular range. The boom (4) is arranged on said articulated arm in a horizontally rotatable way. The boom (4) is connected to a lift truck (15) with pivot bearings (16) that can be displaced along the articulated arm (13) and/or the boom (4). The boom (4) can be rotated about the pivot bearings in such a way that it is aligned always at a right angle to the casting strand direction during the flame cutting by NC control. The articulated arm (13) also accommodates the tools and equipment supply, and optionally the cooling water supply, and supply lines and control cables as collection line (21).
