Abstract

La presente invenci?n est? dirigida a un m?todo y aparato de producci?n de una tira de acero galvanizado de fase dual con conformabilidad mejorada, manteniendo al mismo tiempo una alta resistencia a la tracci?n. La presente invenci?n comprende una etapa de enfriamiento y una etapa de recocido. En la etapa de enfriamiento, la tira de acero galvanizado tiene una reducci?n de temperatura de aproximadamente 300?C a aproximadamente 150?C-250?C. Esta etapa de enfriamiento debe enfriar hasta un grado m?ximo de aproximadamente 150?C diferente entre la temperatura inicial y la temperatura final. Este enfriamiento puede lograrse por medio de un enfriamiento r?pido con agua caliente, o con el uso de una torre de enfriamiento, u otros medios. La etapa de recocido debe seguir a la etapa de enfriamiento. La etapa de recocido debe calentar la tira de acero galvanizado hasta una temperatura de aproximadamente 340?C - 390?C. Este recocido hace que la martensita en la tira de acero galvanizado sea templada a una temperatura relativamente baja, lo cual reduce la formaci?n de la fase Fe-Zn en el revestimiento de GI.
