Automobile parts under construction. The front axle of an automobile. Microscopic view of the axle before heat treatment. Cars moving across a field. Axles are treated in a huge automatic furnace. Interior of a building. Men working on the treatment of axles. Flame is kept away from metal while heating. Heat reaches the axles through numerous small openings. The temperature must be raised slowly and evenly to a specified degree and held there. A man turns a knob. Each furnace is equipped with electric temperature indicators called 'pyrometers'. The temperature is automatically recorded in the control office. Variations in temperature are recorded. Lines being drawn to indicate the variations in temperature. The straightness of the line indicates the uniformity of the temperature. Each furnace has a deviation indicator, showing slightest variation from the specified temperature. The furnaces are also equipped with signal lights. If the temperature gets too high, the red light glows and in case of too low temperature, the blue light glows. The white light indicates correct temperature.

Processing and cooling of axles in an oil bath during heat treatment of metal in the United States.

The heat treatment of front axles of automobiles in the United States. Interior of a building. The axles slowly move through a furnace with the temperature gradually increasing. The temperature is held at a point for 15 minutes to ensure absolute uniformity. The axles automatically descend into an oil bath after this process. The oil must be kept at the proper temperature to give the steel maximum strength. The oil temperature is recorded in the control office. The oil is cooled by cold water pipes. The water is cooled by fountain sprays. A storage tank replaces the oil. Cooling of the axles in the oil bath. This completes the first step of heat treatment called hardening. Metal at this stage is viewed under a microscope. Comparison of the appearance before and after hardening. Tempering of the metal to relieve the strains set up during the hardening process.
