  • Annealing process control method and apparatus
    Patent number: 4595427
    Abstract: A method and an arrangement for following and controlling the progress of heat treatment of cold worked metals in an annealing furnace uses the changing electrical resistivity of the cold worked metal during the annealing process as a process control parameter. A sample of the cold worked metal is placed in a slave furnace along with a sample of the cold worked metal which has been previously annealed. The temperature of the slave furnace is controlled to follow and duplicate the temperature at any point of interest in the annealing furnace, and the differential resistivity between the two samples is measured to follow and control the progress of annealing.
