A professional who sets up and operates hot or cold rolling mill to reduce or form nonferrous metal into plate, sheet, foil, flatwire, and rod of specified dimensions. Respnsibilities include:

• Adjusts rollers, buffs, and guides according to size and dimensions of workpiece, using screwdowns, micrometer, steel tape, and handtools.
• Turns valves and observes gauges to regulate flow, temperature, and solution of roll lubricants and metal coolants.
• Starts entry or rolloff tables that feed metal to and from rolls.
• Threads sheet or rod through rolls for further reduction, or signals rolling-mill-operator helper to feed separate sheets or rods through rolls.
• Controls speed of rolling mill and roll tables to synchronize flow of metal with tandem operations, using signals or communications system.
• Measures width and gauge of rolled metal, using linear tape and depth gauge and adjusts rolls to form metal to specifications.
• Observes rolling operation to detect curling, splitting, or buckling of metal.
• May change rolls on rolling machine, using chain or power hoist.
• May be designated according to type of mill operated as tandem-mill operator; or condition of metal rolled as cold-mill operator hot-mill operator.
