Abstract

The conflicting arguments regarding interconnection between widening, forward creep and drawing under lengthwise rolling are specified. It is proved that under complete metal gathering the rolling process itself differs slightly from conventional rolling. The only distinguishing feature is change in the mechanisms of widening and forward creep. The abnormal growth of forward creep under increased reductions is observed. It is established that this abnormal growth cannot be explained from the point of view of modern theory of rolling.
