Abstract

"MéTODO PARA PRODUçãO DE SISTEMAS DE TUBOS DE AçO SEM COSTURA COM ALTO TEOR DE CROMO". A presente invenção refere-se ao fornecimento de um método para produção de um sistema de tubos de aço com alto teor de Cr, tendo uma alta qualidade de superfície interna, com uma alta eficiência e a um reduzido custo de produção. Um material inicial, incluindo Cr a um teor de 10 a 20%, e as impurezas de S e P nos respectivos teores de não mais que 0,050%, é usado para formar um tubo acabado, e quando se usam parâmetros, o período total de uniformização de temperatura <sym>t1 (horas) para uniformização de temperatura do material inicial para formar um material primário de tubos, como um tarugo ou um bloco, e o período total de uniformização de temperatura <sym>t2 (horas) para uniformização de temperatura do material primário de tubos, um tubo acabado é formado a uma temperatura de aquecimento de 1.200<198>C, sob a condição de que a equação (b), a seguir, seja satisfeita: onde f é um fator indicando o grau de geração de ferritas <sym>, de acordo com os teores dos elementos ali incluídos. O método permite que um sistema de tubos de aço sem costura com alto teor de Cr, tendo uma quantidade muito pequena de defeitos na superfície interna seja conformado, usando-se um aço com alto teor de Cr. Uma vez que uma produtividade predeterminada pode ser alcançada sem qualquer adição excessiva de impurezas, um sistema de tubos de aço sem costura com alto teor de Cr, tendo uma alta qualidade de superfície interna, pode ser produzido, com uma alta eficiência.
