Abstract
método de fabricação de um tubo de aço sem costura a partir de um tarugo feito de liga com alto teor de cr e alto teor de nl trata-se de um tarugo feito de liga com alto teor de cr e alto teor de ni, que contém, por porcentagem de massa, 20 a 30 % de cr, 30 a 50 %de ni, e pelo menos um elemento selecionado a partir de mo e w com um valor "mo+ 0,5 w" de 1,5 % ou mais é aquecido sob condições que satisfazem a seguinte fórmula (1), e então o tarugo é perfurado e laminado utilizando um fresa de perfuração do tipo rolo inclinado com uma velocidade circunferencial do sulco do rolo de 2,28 m/seg ou mais. isso impede erupção fundida sobre a superfície interna e aumenta a vida útil do mandril. t menor maior que 1575-4.45xvf-104. 7x{-ln(th/ro)} (1) em que t indica uma temperatura de aquecimento (°c) do tarugo, v f indica a velocidade circunferencial do sulco do rolo (m/seg), r o indica um raio (mm) de um tarugo em um lado de entrada, e th indica j.ima espessura radial (mm) de um tubo após a perfuração.
