Abstract:
Apparatus and method is disclosed for on-line monitoring for early detection of diagonal distortion in a moving cast product ideally having a rectangular cross-section. A pair of contact rollers is supported on respective guide arms at a location along the casting path and biased to resiliently impinge on opposite edges of the moving cast product. A detector continuously senses the amount of separation between the contact elements to detect diagonal distortion in casting cross-section. A recorder is used to provide a tangible record of such variation. Optionally, both diagonals can be measured, and their sum or difference continuously monitored as well. A fixed support member carries the arms on slidable linear motion bearing structure to facilitate translational motion of the contact elements relative to the casting path, to minimize the effect of casting motion waver on contact separation.
