Operate or tend machines, such as furnaces, baths, flame-hardening machines, and electronic induction machines, to harden, anneal, and heat-treat metal products or metal parts.

Cleans oxides and scale from parts or fittings, using steam spray or immersing parts in chemical and water baths. Signals forklift operator to deposit or extract containers of parts into and from furnaces and quenching rinse tanks. Tests parts' for hardness, using hardness testing equipment, and stamps heat treatment identification mark on part, using hammer and punch. Examines parts to ensure metal shade and color conform to specifications, utilizing knowledge of metal heat-treating. Removes parts from furnace after specified time and air dries or cools parts in water or oil brine or other baths. Reduces heat and allows parts to cool in furnace. Positions part in fixture, presses buttons to light burners and tends flame hardening machine, according to procedures, to case-harden metal part. Adjusts speed and operates continuous furnace through which parts are passed by means of reels and conveyors. Sets up and operates die-quenching machine to prevent parts from warping. Reads production schedule to determine processing sequence and furnace temperature requirements for objects to be heat treated. Activates and tends electric furnace that anneals base sections of hardened parts for subsequent machining. Sets automatic controls, observes gauges, and operates gas or electric furnace used to harden temper, or anneal metal parts. Loads parts into containers, closes furnace door, and inserts parts into furnace when specified temperature is reached. Covers parts with charcoal before inserting in furnace to prevent discoloration caused by rapid heating.
