Task statements

• [Core] Adjust and correct machine set-ups to reduce thicknesses, reshape products, and eliminate product defects.
• [Core] Monitor machine cycles and mill operation to detect jamming and to ensure that products conform to specifications.
• [Core] Examine, inspect, and measure raw materials and finished products to verify conformance to specifications.
• [Core] Read rolling orders, blueprints, and mill schedules to determine setup specifications, work sequences, product dimensions, and installation procedures.
• [Core] Manipulate controls and observe dial indicators to monitor, adjust, and regulate speeds of machine mechanisms.
• [Core] Start operation of rolling and milling machines to flatten, temper, form, and reduce sheet metal sections and to produce steel strips.
• [Core] Set distance points between rolls, guides, meters, and stops, according to specifications.
• [Supplemental] Thread or feed sheets or rods through rolling mechanisms, or start and control mechanisms that automatically feed steel into rollers.
• [Core] Position, align, and secure arbors, spindles, coils, mandrels, dies, and slitting knives.
• [Core] Direct and train other workers to change rolls, operate mill equipment, remove coils and cobbles, and band and load material.
• [Core] Fill oil cups, adjust valves, and observe gauges to control flow of metal coolants and lubricants onto workpieces.
• [Core] Record mill production on schedule sheets.
• [Core] Install equipment such as guides, guards, gears, cooling equipment, and rolls, using hand tools.
• [Core] Signal and assist other workers to remove and position equipment, fill hoppers, and feed materials into machines.
• [Core] Calculate draft space and roll speed for each mill stand to plan rolling sequences and specified dimensions and tempers.
• [Supplemental] Select rolls, dies, roll stands, and chucks from data charts to form specified contours and to fabricate products.
• [Core] Activate shears and grinders to trim workpieces.
• [Supplemental] Remove scratches and polish roll surfaces, using polishing stones and electric buffers.
• [Supplemental] Disassemble sizing mills removed from rolling lines, and sort and store parts.
