    摘要: The invention relates to a method for heat-treating a metal component. The invention relates in particular to an application in the partial hardening of optionally pre-coated components made of high-strength manganese-boron steel. With the method, at least one first sub-region (2) of the component (1) is convectively cooled by means of at least one nozzle (3), which discharges a fluid stream (4) to the first sub-region (2) so that a temperature difference (5) of at least 100 K is set between the at least one first sub-region (2) and at least one second sub-region (6) of the component (1), wherein the at least one nozzle (3) is operated with an overpressure of at least 2 bar.

    摘要: The invention relates to a heat treatment system, in particular a roller hearth furnace. The heat treatment system comprises a useful space having a first region with a width B1 and a second region with a width B2, wherein the rollers are arranged in the first region, and wherein width B2 is greater than width B1. In this context, "width" is understood to be the dimension that is transverse to the through-flow direction of the furnace. Width B1 is thereby measured such that the rollers have a length at which, even when there is a temperature in the furnace for the heat treatment of metal components, they still have such a mechanical stability, for example, that their bending remains within acceptable tolerances, even in the loaded state. The second region of the useful space extends above the first region of the useful space, with the greater width B2, such that components with a maximum width B2, greater than width B1, can also be heat treated.

    摘要: The invention relates to a method and a device for the heat treatment of a metal component, and a use of a furnace for heating a metal component. The invention can be used in the partial hardening of optionally pre-coated components made of a high-strength manganese-boron steel. A method according to the invention for the heat treatment of a metal component (1) comprises at least the following steps: a) heating the component (1) in a first furnace (2); b) moving the component (1) into a tempering station (3); c) cooling at least one first sub-region (4) of the component (1) in the tempering station (3), wherein a temperature difference is set between the at least one first sub-region (4) and at least one second sub-region (5) of the component (1); d) moving the component (1) from the tempering station (3) into a second furnace (6); e) heating at least the at least one first sub-region (4) of the component (1) in the second furnace (6) by at least 200 K.

    摘要: The invention relates to a method and to an apparatus for impressing a temperature profile onto a sheet steel component (200), wherein in one or more first areas (210), a temperature below the AC3 temperature can be impressed on the sheet steel component (200), and in one or more second areas (220), a temperature above the AC3 temperature can be impressed on the sheet steel component (200), and is characterized in that the sheet steel component (200) is firstly preheated in a production furnace (110), the sheet steel component (200) is then transferred into a thermal re-treatment station (150), wherein a radiant heat source (151) is moved over the component in the thermal re-treatment station (150), by means of which the one or more first areas (210) of the sheet steel component (200) can optionally be kept at a temperature above the AC3 temperature or or cooled down further, and the one or more second areas (220) of the sheet steel component (200) can optionally be heated to or or kept at temperature above the AC3 temperature.
