<p>The procedure for continuous hardening of steel strips (10), comprises heating the strip material for hardening on a hardening temperature, quenching the strips, and pressing the strips mechanically under simultaneous heating to tempering temperature. During the pressing, the strip material is heated quickly with heating gradients of 500 K/s on tempering temperature and held at the tempering temperature as well as finally cooled down. The surface of the steel strip is covered with a protection cover (5, 6). The pressing is accomplished under productive gas atmosphere.

The surface of the steel strip is covered with a protection cover (5, 6). The pressing is accomplished under productive gas atmosphere. The heating of the steel strip takes place by means of inductive heating. An independent claim is included for a device for continuous hardening of steel strips.</p> |
