What the work involves

Set up, operate, or tend machines to roll steel or plastic forming bends, beads, knurls, rolls, or plate, or to flatten, temper, or reduce gauge of material.

Main tasks

  • Monitor machine cycles and mill operation to detect jamming and to ensure that products conform to specifications.
  • Adjust and correct machine set-ups to reduce thicknesses, reshape products, and eliminate product defects.
  • Start operation of rolling and milling machines to flatten, temper, form, and reduce sheet metal sections and to produce steel strips.
  • 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 to monitor, adjust, and regulate speeds of machine mechanisms.
  • Set distance points between rolls, guides, meters, and stops, according to specifications.
  • Calculate draft space and roll speed for each mill stand to plan rolling sequences and specified dimensions and tempers.
