  • Method and apparatus for monitoring pass alignment in rolling mills
    Patent number: 4059794
    Abstract: A method of, and apparatus for, monitoring the alignment of a pass defined between cooperating rolls in a mill stand during rolling bar, rod or section stock. Measurement is effected through eddy current sensors which are mounted in close proximity to the ends of the rolls and provide an output indicative of the amount by which they are spaced from the roll surface. In some instances other parameters e.g. roll wear, are also measured by similar eddy current sensors appropriately located in close proximity to the roll surfaces.
