Abstract
A method for rolling a ring-shaped rolling product (5) having an open cylindrical cross section in a ring rolling machine (1) with inductive heating of the rolling product (5) during the rolling process uses at least one inductor (12) which is held at a predefined coupling distance relative to the rolling product (5) and is tracked or carried along during the shaping process in accordance with the change in dimensions of the rolling product (5). An alternating magnetic field, preferably with a frequency of between 4 and 10 kHz, is coupled directly into the rolling product (5) using the inductor (12).
