Abstract
trata-se de um método e um aparelho para fabricação de um trilho em que tanto uma seção de cabeça como uma seção de pé têm uma alta ductilidade. são revelados um método de fabricação de trilho e um aparelho de fabricação de trilho através dos quais: um material de trilho de aço aquecido é laminado a quente; a temperatura é ajustada resfriando-se o material de trilho de aço laminado a quente; o material de trilho de aço que foi submetido ao ajuste de temperatura é processado em um formato de trilho por meio de laminação com temperatura ajustada em uma taxa de redução de área igual ou maior do que 20% e, no momento de ajustar a temperatura do material de trilho de aço, a temperatura de superfície de porções do material de trilho de aço, isto é, uma seção de cabeça e uma seção de pé do formato de trilho, é reduzida para 500°c a 1.000°c.
