The trailing end of the billet (12a) being rolled is welded to the leading end of the billet (12b) unloaded afterwards from the furnace (11) while the billets (12) are in movement by a welding assembly (20) mounted on a movable trolley (19). The movable trolley (19) is taken substantially to the rolling speed, grips the billets (12) with the jaws (31) of the welding unit (20) and welds the ends of the billets (12). The welding step is preceded by a descaling step carried out by a descaling unit (16) wherein the front faces of the billets (12) and at least those areas of the billets (12) cooperating with the jaws (31) are descaled and by a parallel plane cropping step of the trailing end and leading end of the billets (12) carried out by a cropping unit (29) mounted on the movable trolley (19) immediately upstream of the welding assembly (20). The welding step is followed by a step to remove the flashes carried out by a flash removal unit (38) while the billet (12) is in movement.

摘要： Discharge device for discharging liquid steel into a roller crystallizer for the continuous casting of thin strip capable of reducing turbulence at the meniscus to a minimum so as to eliminate the relative defects on the cast strip by passing the steel between two crystallizer rollers. A relative casting process is also described, said process providing for particular expedients for improving the steel feeding from the tundish to the crystallizer. Advantageously, the feeding of guided steel jet streams inside the nozzle, or delivery nozzle, eliminates the disturbance at the meniscus caused by the air bubbles which form when free-falling jet streams come into contact with the air, as occurs in the known devices and plants.
