摘要

this found refers to a process and to a group of hot and cold rolling of ferrous and nonferrous metals for the production of a bar or wire rod by a rod or 'roundsome round of greater diameter.the process involves introducing a bar or wire rod with initial profile round cross-section in a group laminante with rolls with profiles definenti a ride rounddiameter less than the diameter of the bar or wire rod in front.upstream of the laminante.the bar or wire rod is subjected to the action of major diameter roller profile acts to change the crazy bar or wire rod of greater diameter according to a shape factor,out of the group laminante, a bar or wire rod with round cross-section of lesser diameter.
