Abstract

PURPOSE: To reduce the load of large sized work rolls, to extend the period for roll changing and to improve rolling efficiency by disposing the plural large sized work rolls to a single type planetary mill consisting of a planetary roll and the large sized work rolls.
CONSTITUTION: A rolled material 15 is rolled successively between a planetary roll arrayed with multiple small sized work rolls 13 around a driving roll 12 and plural large sized work rolls 14-1W14-4. At this time, tensile force is exerted upon the material 15 by the rolls 14-1W14-4 and therefore the load acting upon each work roll is reduced and the feeding of the material is made easy. Further, the period for roll changing owing to the abrasion of the work rolls 14-1W14-4 is extended and the dimensional accuracy and flatness are improved.
