摘要

Process for the production of a process component for the production of a process component for the production of a shaped component (22) with areas of different resistenciaconformado (22) with areas of different resistenciaconformado (22) with areas of different resistance (10,230) to from a cold rolled ((10,230) from a cold rolled ((10,230) from a cold rolled (1) side, wherein the cold rolled strip (1) obtiene1) band band where cold rolled (1) obtiene1) band, where the cold rolled (1) band is obtained by laminating cooled, recrystallization annealing by laminate cooled, recrystallization annealing laminated cooled, recrystallization annealing and cooling the steel strip and after cooling ey steel strip and, after cooling ey steel strip and, after cooling, it has a thickness yuna connfriamiento resistance, has a thickness yuna connfriamiento resistance, has a constant yuna thickness resistance throughout its length, a procedure stant throughout its length, a procedure stant throughout its length, a procedure that the shaped component (22) is performed medianque component takes formed (22) medianque forming component (22) is performed by a mechanical forming process from lte a mechanical forming process from lte a mechanical forming process after the cold rolled strip (1), where a sistemade aa cold rolled (1) band, where a sistemade aa cold rolled strip (1), where a sistemade power supply (8) applied locally energlimentación energy (8) applied locally energlimentación energy (8) locally applied energy a first thermal zone (10) of the thermal lapped web to a first zone (10) of the thermal lapped strip to a first zone (10) of the cold laminadaen band (1 ) After cooling and before Inadaen cold (1) after cooling and before Inadaen cold (1) after cooling and before the mechanical forming process, the first zone (the mechanical forming process, the first zone (the mechanical forming process, first zone (10) quecorresponde to an area of ​​the component confo10) quecorresponde to an area of ​​the component confo10) quecorresponde to an area of ​​the shaped component (22) of least resistance, or where then signed (22) of least resistance, or where after , rmed (22) of least resistance, or where then delenfriamiento, reheated in its totalidelenfriamiento, reheated in its totalidelenfriamiento, reheated in whole or in part the cold rolled strip (1) age or partially cold rolled strip (1) age or partially cold rolled (1) in an oven (217), preferably in the range of lan an oven (217), preferably in the range of band lan an oven (217), preferably in the range from the recrystallization temperature, and where recrystallization temperature was applied, and where recrystallization temperature was applied, and where locally refrigerant unmedio applies a system gives locally unmedio coolant system gives locally refrigerant unmedio with a system power supply, comprising a sisteme power supply comprising a sisteme power supply, comprising a cooling system (216), in a second zone (230) of a coolant (216), in a second zone (230) of a coolant (216) in a second zone (230) of the cold rolled strip (1) again calentadala cold rolled strip (1) again calentadala cold rolled strip (1) reheated in order to increase the segund laresistencia in order to increase the segund laresistencia in order to increase laresistencia in the second zone (230), wherein the b I goes laminaa area (230), wherein the laminaa band area (230), wherein the cold rolled (1) web travels at a speed predeteda cold (1) moves at a speed predeteda cold (1) moves at a predetermined speed and because elsistema power enerrminada and because elsistema power enerrminada and because elsistema power supply (8) moves simultaneously with the laminagía band (8) moves simultaneously with the laminagía band (8) simultaneously moving the cold rolled (1), medianteun device transporda cold (1), medianteun device transporda cold (1), medianteun transport device (140), parallel to the upper side of the Bante (140) band parallel to the upper side of the Bante (140) parallel to the upper side of the cold rolled strip (1), for aplicarlocalmente enda cold rolled (1), for aplicarlocalmente enda cold rolled ( 1) to aplicarlocalmente thermal energy on cold rolled thermal Mergia on cold rolled thermal Mergia on the cold rolled strip moving strip.
