Their functions include: operating rolling mills to shape hot steel ingots into blooms, slabs, billets or sheet bars for further processing, or to shape heated semi-finished steel pieces into bars, angles, ties, rails, sheets or other finished forms; operating continuous mills in which hot steel slabs are passed through a series of rolls (stands) to produce finished plates or sheets in one continuous operation; operating rolling mills to reduce cold steel strip or sheet to required gauge and impart desired finish; operating rolling mills to reduce or form hot or cold non-ferrous metal into plate, sheets, foil, wire or rod of specified dimensions; operating rolls to form seamless tubes and pipes from billets which have been pierced longitudinally; manipulating controls of a rolling mill according to signals from roller; performing related tasks."@en ;
