Apparatus for inspecting the geometry of dual roller tracks for continuous castings

摘要

A parallelogram-like collapsible frame has centering rolls in opposite corners for engaging one roll each per track and across the track path; these centering rolls establish a center line of reference on which one or two, straight or curved rulers are pivoted to engage other track rollers, and the angle of pivoting represents the radius of curvature or a deviation from a desired radius.
