Abstract

Process for descaling the surface of a casting rod comprises elongating the rod (1) between the end of the rod support (10) and before the inlet to the compensating oven (11) or before the inlet to the roll stand (33) in a limited region by a two-stage deflection from the horizontal transporting device in the region of each deflection (4, 5), and intensively cleaning the rod surfaces (2, 3) especially in the deflecting regions (4, 5) using hard water jets (8, 9). An Independent claim is also included for an apparatus for carrying out the descaling process.
