Abstract: A device (100) for covering the welding area for hot rolling lines consists of an outer container (1), a protective shield (2), a blade-holder (3) with scraping blades, and an actuator (9). Protection occurs by linearly sliding the protective shield (2) outside the outer container (1) up to minimizing the gaps with the billets. The cleaning occurs at the same time as the return to the rest position: the scraping blades, which are integral with the container (1) and are installed in contact with the inner surface of the protective shield (2), slide thereon during the raising, thus colliding with the deposits of solidified material and removing them. Completing the device (100) additionally is a small alternating linear motion of the protective shield (2) during operation to always keep the attachment area of the scraping blades clean, thus avoiding the need for excessive detachment forces at the beginning of the raising.

Abstract: A rolling plant for rolling billets or blooms, the plant defining a longitudinal feeding axis X of said billets or blooms and comprising a feeding area for feeding said billets or blooms; a rolling train; a longitudinal roller table to transport the billets or blooms from said feeding area to said rolling train along said longitudinal feeding axis X; a welding machine adapted to move forwards and backwards along said longitudinal roller table to weld billets or blooms to one another when moving from said feeding area to said rolling train; characterized in that said welding machine is slidingly suspended from a bridge and is adapted to translate parallel to said longitudinal feeding axis X, and said bridge is arranged at the longitudinal roller table and is adapted to translate transversely to said longitudinal feeding axis X, whereby in a first operating position of the bridge the welding machine occupies part of the longitudinal roller table and can move forwards and backwards along said longitudinal fe
