• Record production data, and maintain production logs.
• Operate controls to move or discharge metal workpieces from furnaces.
• Weigh materials to be charged into furnaces, using scales.
• Regulate supplies of fuel and air, or control flow of electric current and water coolant to heat furnaces and adjust temperatures.
• Inspect furnaces and equipment to locate defects and wear.
• Observe air and temperature gauges or metal color and fluidity, and turn fuel valves or adjust controls to maintain required temperatures.
• Kindle fires, and shovel fuel and other materials into furnaces or onto conveyors by hand, with hoists, or by directing crane operators.
