  • Patent number: 4126028
    Abstract: A method and apparatus are disclosed for the stressless rolling of metals in a continuous rolling mill. In a continuous train, between any two successive mill stands, the magnitude of the rolling torque in the first mill stand is measured and stored just before the metal enters the second mill stand. The rolling torque of the first stand is maintained constant at the stored magnitude until the speed of the first stand is stabilized. Immediately after stabilization is achieved, the ratio of the speeds of the first and second mill stand is held constant until rolling is ended.
