Abstract
A method for monitoring the manufacturing process of hot-rolled tubes in which the type and dimensional characteristics of structures produced by the rolling process on an outer surface of the tube are evaluated to assess the process state. Immediately subsequent to the rolling process in the exit side region of a rolling stand the outer surface of at least one defined portion of the tube is detected by measuring technology, linearly by means of an optical laser stripe method and in a clocked manner in the form of profile lines, and the profile lines are then combined to form an at least two-dimensional topography and the topography is evaluated to assess the process state.
