Adjust and correct machine set-ups to reduce thicknesses, reshape products, and eliminate product defects. Monitor machine cycles and mill operation to detect jamming and to ensure that products conform to specifications. Examine, inspect, and measure raw materials and finished products to verify conformance to specifications. Read rolling orders, blueprints, and mill schedules to determine setup specifications, work sequences, product dimensions, and installation procedures. Manipulate controls and observe dial indicators in order to monitor, adjust, and regulate speeds of machine mechanisms. Start operation of rolling and milling machines to flatten, temper, form, and reduce sheet metal sections and to produce steel strips. Set distance points between rolls, guides, meters, and stops, according to specifications. Thread or feed sheets or rods through rolling mechanisms, or start and control mechanisms that automatically feed steel into rollers. Position, align, and secure arbors, spindles, coils, mandrels, dies, and slitting knives. Direct and train other workers to change rolls, operate mill equipment, remove coils and cobbles, and band and load material. Fill oil cups, adjust valves, and observe gauges to control flow of metal coolants and lubricants onto workpieces. Record mill production on schedule sheets. Install equipment such as guides, guards, gears, cooling equipment, and rolls, using hand tools. Signal and assist other workers to remove and position equipment, fill hoppers, and feed materials into machines.
