Abstract

método de arreficimento para tubo de aço trata-se de um método para arrefecer um tubo de aço (1) mediante o resfriamento com água a partir de uma superfície externa do mesmo, em que as porções de extremidade do tubo não são submetidas ao resfriamento com água, e pelo menos parte de um corpo principal diferente das porções de extremidade do tubo é submetida ao resfriamento com água. é desejável adotar uma modalidade na qual uma região(s) que não é submetida ao resfriamento direto de água axial pelo menos na parte do corpo principal além das porções de extremidade do tubo; uma modalidade em que o início e interrupção do resfriamento com água ão repetidos intermitentemente pelo menos em parte de um processo de arreficimento; ou uma modalidade em que mediante a realização do resfriamento com água de uma superfície externa do tubo de aço, um resfriamento com água de uma superfície externa do tubo de aço, um resfriamento com água intensificado é realizado em uma faixa de temperatura em que a temperatura da superfície externa do tubo de aço é maior que o ponto ms, e posteriormente o refriamento com água intensificado é comutado para um resfriamento com água moderado ou resfriamento com ar de modo que a superfície externa seja forçadamente resfriada até o ponto ms ou mais baixo. esse método de arreficimento pode ser aplicado adquadamente ao tratamento de arreficimento de um tubo de aço feito de um tipo de aço com médio ou alto teor de carbono (um tubo de aço do aço de baixa liga ou aço de méia liga) ou um tubo de aço inoxidável martensítico.
