METHOD AND DEVICE FOR DETERMINING THE WEAR PROPERTIES OF COATED FLAT PRODUCTS BY MEANS OF BENDING

摘要

The invention relates to a method for determining the wear properties of coated flat products (1), preferably flat metal products, in particular flat steel products, such as galvannealed flat steel products. In order to be able to achieve better comparability of the determined wear properties of different flat products, such a method is proposed, wherein at least one bending parameter for the bending of the particular flat product (1) by means of a bending device (4) is selected in accordance with defined criteria on the basis of information regarding the thickness and/or the strength of the particular flat products (1) to be bent, wherein the flat products are bent in the bending device (4) in accordance with the selected bending parameters, wear (25) thus being produced, and wherein the wear properties are analyzed in a predetermined manner on the basis of the wear (25) of the particular flat products (1).
