Abstract

MéTODO DE PRODUçãO DE TIRA DE AçO LAMINADA A QUENTE REVESTIDA POR IMERSãO A QUENTE. A presente invenção refere-se a uma produção de tira de aço laminada a quente revestida por imersão a quente pelo processo de lingotamento contínuo de placas finas e laminação a quente, a mencionada tira de aço contendo, em % em massa, C: 0,03% ou mais, Si: 0,02% ou mais, Mn: 0,15% ou mais, e Ca: 0,001% ou mais pelo aquecimento da mesma até uma temperatura máxima de pico da tira de aço de 550°C até menos de 650°C por uma taxa de elevação de temperatura de 25°C/s ou mais por 15 segundos ou mais para oxidação, aquecendo-se a mesma até uma temperatura máxima de pico da tira de aço de 700 a 760°C de forma que o tempo em que a temperatura da tira de aço é de 570°C ou mais é de 25 segundos a 45 segundos para redução, e então revestindo-a por imersão a quente.HOT LAMINATED STEEL STRIP METHOD PRODUCTION METHOD. The present invention relates to a production of hot-dip coated hot-rolled steel strip by continuous casting process and hot-rolling, said steel strip containing, by weight, C: 0, 03% or more, Si: 0,02% or more, Mn: 0,15% or more, and Ca: 0,001% or more by heating it to a maximum steel strip peak temperature of 550 ° C to minus 650 ° C for a temperature rise rate of 25 ° C / s or more for 15 seconds or more for oxidation by heating it to a maximum steel strip peak temperature of 700 to 760 ° C that the time at which the temperature of the steel strip is 570 ° C or more is 25 seconds to 45 seconds for reduction, and then hot dip coating.
