Heat Treating Equipment Setters, Operators, and Tenders, Metal and Plastic
Description
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.
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.
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.
Determine types and temperatures of baths and quenching media needed to attain specified part hardness, toughness, and ductility, using heat-treating charts and knowledge of methods, equipment, and metals.
Remove parts from furnaces after specified times, and air dry or cool parts in water, oil brine, or other baths.
Position stock in furnaces, using tongs, chain hoists, or pry bars.
Instruct new workers in machine operation.
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.
Determine flame temperatures, current frequencies, heating cycles, and induction heating coils needed, based on degree of hardness required and properties of stock to be treated.

Mount workpieces in fixtures, on arbors, or between centers of machines.
Set up and operate die-quenching machines to prevent parts from warping.
Move controls to light gas burners and to adjust gas and water flow and flame temperature.
Reduce heat when processing is complete in order to allow parts to cool in furnaces or machinery.
Signal forklift operators to deposit or extract containers of parts into and from furnaces and quenching rinse tanks.

Position plastic sheets and molds in plastic bags, heat material under lamps, and force confrontation of sheets to molds by vacuum pressure.
Examine parts to ensure metal shades and colors conform to specifications, utilizing knowledge of metal heat-treating.
Cover parts with charcoal before inserting them in furnaces, in order to prevent discoloration caused by rapid heating.
Repair, replace, and maintain furnace equipment as needed, using hand tools.

Heat billets, bars, plates, rods, and other stock to specified temperatures preparatory to forging, rolling, or processing, using oil, gas, or electrical furnaces.
Clean oxides and scales from parts or fittings, using steam sprays or chemical and water baths.
Place completed workpieces on conveyors, using cold rods, tongs, or chain hoists, or signal crane operators to transport them to subsequent stations.
Stamp heat-treatment identification marks on parts, using hammers and punches.
Set and adjust speeds of reels and conveyors for prescribed time cycles in order to pass parts through continuous furnaces.
Mount fixtures and industrial coils on machines, using hand tools.
Attach wire or metal to winding mechanisms that will pull parts through furnaces.
Place parts on carts, connect vacuum lines to vacuum tubes, and smooth bags around parts to ensure vacuum.
Position parts in plastic bags, and seal bags with irons.
