Abstract

The authors developed a new advanced laser scanning range finder. The width gauge consists of a pair of these range finders. Conventional gauges cannot measure the effective width of complexly shaped plate edges. However, the gauge measures both side profiles of a plate and calculates the effective width with an accuracy of +/- 1.5 mm. This new type of width gauge has been developed and tested at the plate rolling mill at Kashima Steel Works of Sumitomo Metal Industries Ltd.
