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.
