Tasks

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.
Clean oxides and scales from parts or fittings, using steam sprays or chemical and water baths.
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.
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.
Examine parts to ensure metal shades and colors conform to specifications, using knowledge of metal heat-treating.
Heat billets, bars, plates, rods, and other stock to specified temperatures preparatory to forging, rolling, or processing, using oil, gas, or electrical furnaces.
Instruct new workers in machine operation.
Load parts into containers and place containers on conveyors to be inserted into furnaces, or insert parts into furnaces.
Mount fixtures and industrial coils on machines, using hand tools.
Mount workpieces in fixtures, on arbors, or between centers of machines.
Move controls to light gas burners and to adjust gas and water flow and flame temperature.
Position stock in furnaces, using tongs, chain hoists, or pry bars.
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.
Reduce heat when processing is complete to allow parts to cool in furnaces or machinery.
Remove parts from furnaces after specified times, and air dry or cool parts in water, oil brine, or other baths.
Repair, replace, and maintain furnace equipment as needed, using hand tools.
Set and adjust speeds of reels and conveyors for prescribed time cycles to pass parts through continuous furnaces.
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.
Signal forklift operators to deposit or extract containers of parts into and from furnaces and quenching rinse tanks.
Stamp heat-treatment identification marks on parts, using hammers and punches.
Start conveyors and open furnace doors to load stock, or signal crane operators to uncover soaking pits and lower ingots into them.
Test parts for hardness, using hardness testing equipment, or by examining and feeling samples.
