摘要

Process for surface treatment of metallic workpieces (2) comprises using inductive heat treatment, in which the workpiece is held by a spring-loaded front-sided loading device. The loading force is kept constant during the change in length of the workpiece determined by the heat treatment. An Independent claim is also included for a device for the surface treatment of metallic workpieces comprising a loading device (1) having a spring (6') for holding the workpiece between its two front ends, and an inductor. The loading device has a length measuring unit (8') and/or a force measuring unit. The loading device has a computer-controlled adjusting drive (11', 11'') in the longitudinal direction of the workpiece.
