Title (EN) SHEET STEEL AND METHOD FOR PRODUCING SHEET STEEL
(FR) TOLE D'ACIER ET SON PROCEDE DE FABRICATION
Abstract: front page image
(EN)A method for producing sheet steel which comprises the steps of producing a crude bar by rough rolling, subjecting the crude bar to finish rolling, to produce a steel belt, subjecting the steel belt to primary cooling and secondary cooling, and winding up the resultant steel belt after the secondary cooling, wherein the primary cooling is carried out with a cooling rate greater than 120°C/sec down to a temperature of 500 to 800°C and the secondary cooling is carried out with a cooling rate less than 60°C/sec.
(FR)Cette invention concerne un procédé de fabrication de tôle d'acier qui englobe les opérations suivantes : réalisation d'une barre par laminage grossier, réalisation d'une lame d'acier par laminage de finition, refroidissement primaire et refroidissement secondaire de la lame d'acier et enroulement de la lame d'acier au terme du refroidissement secondaire. Le refroidissement se caractérise par un taux de refroidissement supérieur à 120 °C/seconde, avec abaissement de la température jusqu'à 500-800 °C et un taux de refroidissement secondaire inférieur à 60 °C/seconde.
