Title:
熱処理方法及び熱処理装置
Document Type and Number:
Japanese Patent JP7168450
Kind Code:
B2
Abstract:
The invention relates to a method and to a device for the heat treatment of a steel component directed specifically at individual zones of the component. In one or more first regions of the steel component a primarily austenitic structure can be set, from which, by quenching, a predominantly martensitic structure can be produced, and in one or more second regions of the steel component there is a predominantly ferritic-pearlitic structure. The steel component is first of all heated in a first furnace to a temperature below the Ac3 temperature, and the steel component is then transferred into a handling station. During the transfer the steel component can cool, and in the handling station, one or more second regions of the steel component are cooled within a residence time t150 to a final cooling temperature ϑS, and is then transferred to a second furnace, in which heat is delivered to the steel component. The temperature of the one or more second regions increases again during the residence time t130 to a temperature below the Ac3 temperature, whilst the temperature of the one or more first regions is heated in the same residence time t130 to a temperature above the Ac3 temperature.
