ABSTRACT:
A method for continuous rolling includes flash-butt welding to form a continuous billet by joining a rear end of a preceding billet with a front end of a succeeding billet, removing burrs from a welded portion of the joined part, and continuously rolling the joined continuous billet in a rolling mill group. The flash-butt welding step includes the use of two travelling welders arranged in series and spaced at a distance along the direction of movement of the continuous billet corresponding to the length of the billet being welded. The travelling welders synchronously move with the continuous billet, and separately and simultaneously weld the continuous billet to another billet by flash-butt welding so as to extend the length of the continuous billet.
