Abstract

máquina laminadora endireitadeira e método de fabricação de um cano ou tubo ou de uma barra. provê-se uma máquina laminadora endireitadeira que permite laminação redutora de diâmetro externo e laminação de endireitamento de um material de cano ou tubo ou de um material de barra em alta velocidade com alta precisão. a máquina laminadora endireitadeira inclui pelo menos dois rolos dispostos transversalmente a uma linha de passagem de um material de cano ou tubo ou de um material de barra, os pelo menos dois rolos tendo um vão entre si, o vão sendo definido por uma porção de laminação redutora de diâmetro externo tendo um diâmetro reduzido a partir de um lado a montante em direção a um lado a jusante na máquina laminadora endireitadeira e uma porção de laminação de endireitamento contínua a partir de um lado de saída da porção de laminação redutora de diâmetro externo em direção a um lado a jusante da máquina laminadora endireitadeira, os rolos tendo formatos que são simétricos em torno da linha de passagem na porção de laminação redutora de diâmetro externo e, na porção de laminação de endireitamento, assimétricos à linha de passagem na porção de laminação redutora de diâmetro externo.
