Abstract

The invention relates to a method and a device for detecting the actual state of a hot tube, wherein wall thickness, diameter, temperature and discharge speed from a sizing and stretch reduction rolling mill pertaining to a tube rolling mill are continuously measured without contact. In addition, the outer and inner surfaces are checked for defects, specially cracks and flaws, without causing any damage. The measurements and controls of wall thickness, diameter, temperature and speed all form part of a hot multi-check measurement system, whereby a common tube guide system is used and the measurement and control systems are provided with the data or parameters required for measurement and control.
