A semi-analytical model for predicting the wear contour in rod rolling process

초록

We developed a model which predicts wear contour of grooved roll in the oval-round (or round-oval) pass rolling process. The wear contour is computed by using the linear interpolation of the radius of curvature of an incoming workpiece, that of roll groove and a weighting function which takes into account roll tonnage. The roll wear contour is measured using an in situ roll wear contour reader developed by POSCO. Results show that predicted wear contours are in agreement with those obtained experimentally.
