Abstract

See full text

The invention relates to a method and an apparatus for the targeted heat treatment of specific component zones of a steel component. A predominantly austenitic structure can be created in the steel component in one or more first regions, from which, by quenching, a majority martensitic microstructure can be created; and in one or more second regions, a majority bainitic microstructure can be created, wherein the steel component is initially heated in a furnace to a temperature above the AC3 temperature, the steel component is subsequently transferred into a treatment station, and can cool down during the transfer, and in the treatment station, the one or more second regions of the steel component are cooled down to a cooling finish temperature ϑ2 during a treatment time.
