What the work involves
Set up, operate, or tend heating equipment, such as heat-treating furnaces, flame-hardening machines, induction machines, soaking pits, or vacuum equipment to temper, harden, anneal, or heat treat metal or plastic objects.
Main tasks
- Read production schedules and work orders to determine processing sequences, furnace temperatures, and heat cycle requirements for objects to be heat-treated.
- Record times that parts are removed from furnaces to document that objects have attained specified temperatures for specified times.
- Adjust controls to maintain temperatures and heating times, using thermal instruments and charts, dials and gauges of furnaces, and color of stock in furnaces to make setting determinations.
- Start conveyors and open furnace doors to load stock, or signal crane operators to uncover soaking pits and lower ingots into them.
- Set up and operate or tend machines, such as furnaces, baths, flame-hardening machines, and electronic induction machines, that harden, anneal, and heat-treat metal.
- Remove parts from furnaces after specified times, and air dry or cool parts in water, oil brine, or other baths.
- Move controls to light gas burners and to adjust gas and water flow and flame temperature.
- Instruct new workers in machine operation.
