Abstract
Tren de laminación reductor (1) para la fabricación de tubos (R) sin costuras, el cual presenta una pluralidad de cajas de laminación (10) dispuestas una detrás de la otra en una dirección de transporte (F) de los tubos (R), en cada caso con tres rodillos (11) dispuestos en una distancia angular de 120º; en donde las cajas de laminación (10) están subdivididas en al menos dos grupos (A, B), cada uno con al menos dos cajas de laminación (10); los rodillos (11) de las cajas de laminación (10) adyacentes están relativamente entrecruzados entres sí dentro de un grupo (A, B) en un ángulo aI interno de grupo; y los rodillos (11) de la cajas de laminación (10) de los grupos (A, B) adyacentes están relativamente entrecruzadas entres sí en un ángulo aG de grupo que es menor que el ángulo aI interno de grupo.Reducing rolling mill (1) for the manufacture of seamless tubes (R), which has a plurality of rolling stands (10) arranged one behind the other in a transport direction (F) of the tubes (R) , in each case with three rollers (11) arranged at an angular distance of 120 °; wherein the rolling stands (10) are subdivided into at least two groups (A, B), each with at least two rolling stands (10); the rollers (11) of the adjacent rolling stands (10) are relatively crisscrossed with each other within a group (A, B) at an angle aI inside the group; and the rollers (11) of the rolling stands (10) of the adjacent groups (A, B) are relatively crisscrossed with each other at a group angle aG which is less than the group internal angle aI.
