Abstract
<um>moinho de mandril e método para fabricar cano ou tubo sem costura<mv>. problema a ser resolvido fornecer um moinho de mandril que inclui uma pluralidade de cadeiras de laminação, sendo que em cada uma delas, três rolos sulcados são dispostos, e que pode adequadamente suprimir um fenômeno em que uma barra de mandril se torna impossibilitada de ser extraída de um cano após estiramento e laminação, sem resultar no aumento em custo de instalação e deteorização de capacidade de manutenção, e um método para fabricar um cano sem costura através do uso do moinho de mandril. solução um moinho de mandril em relação à presente invenção inclui uma pluralidade de cadeiras de laminação em que três rolos sulcados r são dispostos em cada cadeira de laminação de modo que um ângulo formado por direções de prensagem seja de 120<198> e as direções de prensagem de rolos sulcados r sejam alternativamente deslocadas por 60<198> entre as cadeiras de laminação adjacentes, em que um ângulo central <sym> que define um arco circular que constitui um perfil de fundo de sulco do rolo sulcado r disposto pelo menos na primeira e na segunda cadeiras de laminação é definido em menos do que 60<198>.
