Abstract

<B><MU>PROCESSO PARA FUNDIR TIRA DE AçO CONTINUAMENTE<MV><D> Na fundição de tira de aço em cilindros gêmeos, introduz-se aço fundido na beliscadura (16B) entre cilindros de fundição paralelos (16) para criar a poça de fundição (30) suportada nas superfícies de fundição (16A) dos cilindros, e os cilindros são submetidos a rotação para distribuírem a tira solidificada (20) descendentemente a partir da beliscadura. As superfícies de fundição (16A) são texturizadas mediante um padrão de projeções distintas aleatórias que são dotadas de picos aguçados e a tira é movimentada para fora da poça de fundição a uma velocidade maior do que 60 metros por minuto. Com a finalidade de suprimir defeitos de trepidação, o aço fundido é dotado de um teor de manganês menor do que 0,6%, em peso, e um teor de silício na faixa de 0,1 a 0,35%, em peso. A textura aleatória poderá ser produzida pelo jateamento abrasivo das superfícies de fundição em um substrato coberto por um revestimento protetor. Alternativamente, a textura poderá ser produzida mediante deposição química ou eletrodeposição de um revestimento em um substrato para formar as superfícies de fundição.
