1,138,822. Rolling. BRITISH IRON & STEEL RESEARCH ASSOCIATION. 25 April, 1966 [23 April, 1965], No. 17339/65. Heading B3M. [Also in Division G3] Longitudinal stresses in a rolled strip 11 are measured at points spaced transversely of the strip by rollers 15 which are held in contact with the strip, the loads acting on the rollers or differences in their positions giving a measure of the stresses. Appropriate pressure or position transducers 16 feed signals to a circuit 17 which actuates an indicator 18 for the use of a mill operator, or causes a negative feedback control loop 20 to automatically control the rolling mil 21 in a manner to remove the stresses. Each roller 15 is mounted in a cradle 14 supported by the ram 13 of an hydraulic cylinder 10. The outer rollers 15 can be adjustable transversely relative to the centre roller, or more than three rollers may be provided. Alternatively, the rollers may be mounted on arms which are each subjected to a torque in order to produce a transverse force on the strip, the angular positions of the arms then providing a measure of transverse stresses acting on the strip. |
