Abstract

La invención se refiere a un procedimiento y a un dispositivo para el tratamiento térmico, dirigido a zonas individuales de elementos constructivos, de un elemento constructivo de acero. En una o varias primeras zonas del elemento constructivo de acero puede ajustarse una estructura principalmente austenítica, a partir de la cual mediante temple rápido puede representarse una estructura en su mayoría martensítica, y en una o varias segundas zonas del elemento constructivo de acero está una estructura en su mayoría perlitica-ferrítica, calentándose el elemento constructivo de acero inicialmente en un primer horno a una temperatura por debajo de la temperatura AC3, transfiriéndose a continuación el elemento constructivo de acero a una estación de tratamiento, pudiendo enfriarse durante la transferencia, y enfriándose en la estación de tratamiento la una o varias segundas zonas del elemento constructivo de acero dentro de un tiempo de permanencia t150 a una temperatura de detención de enfriamiento ?s, transfiriéndose a continuación a un segundo horno, en el que al elemento constructivo de acero se le aporta calor, subiendo la temperatura de la una o varias segundas zonas durante el tiempo de permanencia t130 de nuevo a una temperatura por debajo de la temperatura AC3, mientras que se eleva la temperatura de la una o varias primeras zonas, en el mismo tiempo de permanencia t130, a una temperatura por encima de la temperatura AC3.The invention relates to a method and a device for heat treatment, directed to individual areas of construction elements, of a steel construction element. In one or several first zones of the steel construction element a mainly austenitic structure can be adjusted, from which by means of quick tempering a mostly martensitic structure can be represented, and in one or several second zones of the steel construction element is a structure mostly perlitica-ferritic, the steel building element being initially heated in a first furnace at a temperature below the temperature AC3, the steel building element being then transferred to a treatment station, being able to cool during the transfer, and cooling in the treatment station the one or several second zones of the steel construction element within a residence time t150 at a cooling stop temperature? s, then transferred to a second furnace, in which the steel construction element is adds heat, raising the temperature of one or more second zones during the residence time t130 again at a temperature below the temperature AC3, while the temperature of the one or several first zones is raised, in the same residence time t130, at a temperature above the temperature AC3
