Abstract

See full text

A method for determining the stamping quality of profiled bar includes steps of: a) upstream of the rolling stand performing shaping, the initial speed VA of the starting product is determined and the initial diameter DA or initial cross-sectional area FA are determined contactlessly. b) After the rolling stand, the final speed VE of the end product is measured and the diameter DE or area FE of a virtual enveloping shell for the end product is determined contactlessly. c) The diameter DN of a virtual, round end product is determined contactlessly as DN=square root of (DA2*VA/VE) and/or the average cross-sectional area FNE of the end product (2) is determined contactlessly as FNE=FA*VA/VE. d1) The characteristic stamping variable PKG is calculated, and the characteristic stamping variable PKG is compared with a pre-set setpoint value PKGset. A device for carrying out the method is also provided.
