Method to obtain simultaneously in the cold state a plurality of sections and/or bars (14), starting with a hot-rolled single multiple-section element (10) which is then cooled (12), the sections and/or bars (14) being deemed to be small sections and/or bars (14) in relation to the typical dimensional category of the specific rolling mill (11), the single multiple-section element (10) comprising a plurality of sections and/or bars (14) which have a symmetrical, asymmetric or special cross-section, a web (23) possibly being included between one section and/or bar (14) and another, the hot-rolled single multiple-section element (10) being cooled (12) in line with the rolling mill (11) and then undergoing, without a break of continuity, an operation in the cold state of simultaneous lengthwise splitting (13) to separate the individual small sections and/or bars (14). The single multiple-section element and the resulting individual sections are also protected. <IMAGE> |
