DEVELOPMENT OF INTEGRATED DIE ROLLS FOR LONGITUDINAL-WELDING PIPE MILL
The newly-developed integrated die roll consists of three parts,namely roll body,roll ring andchuck,which results in thickness-increase of the working parts subject to serious wearing,and hencehigher wear resistance is obtained.In addition,each part of the roll is replaceable,so whole-rollscrapping could be avoided.
