Abstract
An apparatus is provided for measuring roll eccentricity. It includes a housing adapted for guided transport in a reference direction tangent to the roll face. The housing is also adapted to rotate the roll at the speed of transport. An elongated runner extending lengthwise in the transport direction is displaceably mounted in the housing. The roll face abuts and displaces the runner but the runner mounting maintains it parallel to the transport direction. Thus, measurements of runner displacement at any point along its length provide an indication of eccentricity of the roll.

An apparatus for measuring the eccentricity of a circumferential face of an axially rotatable roll, said apparatus comprising:
- a housing adapted for transport substantially tangent to the roll face in a direction normal to the roll axis,
- said housing including means (a) for guiding said housing during transport so that an axis thereof is maintained coincident with the transport direction and said transport direction is maintained constant at least for sufficient of the portion of said transport for determining eccentricity of the roll, and (b) for contacting said roll and causing rotation thereof at a circumferential speed equal to the rate of housing transport,
- an elongated measuring runner projecting laterally from said housing so as to be abutted and traversed by said roll along an outer longitudinal surface thereof, said longitudinal surface being parallel to the direction of housing transport and of length sufficient for measurement of eccentricity of said roll,
- means for mounting said measuring runner displaceably in the housing and maintaining said runner parallel to the housing axis in the transport direction, and
- means for measuring the displacement distance of said measuring runner from a reference position in the housing.
An apparatus for measuring the eccentricity of conveying rollers in the secondary cooling zone of continuous casting machines, said apparatus comprising:
- a housing adapted for transport through said cooling zone between the rolls therein,
- said housing having means (a) for guiding the transport thereof, maintaining a housing axis coincident with the transport direction, and maintaining the transport direction constant for a sufficient portion of the transport adjacent each roll face for measurement of the eccentricity thereof, and (b) for contacting each roll so as to cause rotation thereof at a circumferential speed equal to the rate of housing transport,
- at least one elongated measuring runner projecting from each of opposite sides of the housing facing opposite of corresponding rolls in said cooling zone, an outer longitudinal surface of each runner being abutted and traversed lengthwise during transport by the face of each roll adjacent thereto, the outer longitudinal surface of each runner being of length for contact with a sufficient portion of the periphery of each roll for accomplishing a measure of the eccentricity thereof,
- means for mounting each measuring runner displaceably in said housing, and for maintaining said runners parallel to the housing axis in the transport direction, and
- means for measuring the displacement distance of each measuring runner from a reference position in the housing.
