METHOD FOR DETERMINING SPRING-BACK OF A ROLL STAND AND/OR EDGER DURING WORKING OF METAL PRODUCTS, METHOD FOR PRODUCING A METAL PRODUCT BY WAY OF A ROLL STAND AND/OR EDGER, AND DEVICE FOR DETERMINING SPRING-BACK OF A ROLL STAND AND/OR EDGER

摘要

The invention relates to a method for producing a metal product (G) by means of a roll stand (1) and/or edger, to a device for determining spring-back of a roll stand (1) and/or edger, and to a method for determining spring-back of a roll stand (1) and/or edger while metal products (G) are being worked. As a result of at least two reference points (R1, R2, R3, R4) for determining the spring-back being predetermined, at least one of the reference points (R1, R2, R3, R4) being on a stand unit (5), in particular a stand frame (5), that deforms while the metal product (G) is being worked, and of a relative position of the at least two reference points (R1, R2, R3, R4) with respect to each other while the metal product (G) is being worked being determined, and spring-back of the roll stand (1) and/or edger being ascertained therefrom, a method for directly determining the spring-back can be provided, which is considerably more precise than the existing indirect method.
