Title: Thermal treatment of intermediate quenching and quick tempering through eddy currents and a device for applying said treatment to high productivity rolling plants for flat products

Abstract: A method of thermally treating a rolled steel plate comprising receiving the rolled steel plate after it has been rolled to a final thickness, developing a uniformed temperature distribution within the rolled steel plate greater than a critical temperature of the steel plate, and quenching the steel plate while the temperature distribution thereof is still uniform and still exceeds the critical temperature. The critical temperature may be Arl or Acl.
