A transducerized roll was successfully fabricated and installed in the rolling mill. Using a heat exchanger to prevent transducer heating, radial surface displacements of .00006 to .00008 inches at a frequency of 12 KCS could be continuously maintained during rolling. Load reductions of 5 to 16 were obtained while rolling lead at room temperature and aluminum at 500C. No significant effect was observed on copper or steel or aluminum at room temperature. A new roll is being constructed utilizing improved design features and will be compared with the older roll and used in conjunction with it to provide a mill operating with two transducerized rolls.
