In this paper the mechanism and kinematics of the rolling drawing process of the cold rolled ribbed bar have been described The residual stress is experimentally studied,and it′s generation mechanism and distribution are discussed in detai

Based on the experiments,the characters of deformation and technology in drawing fluxcored welding wires through conventional dies and roller dies have been analyzed in this paperThe results indicate that the process of roller dies drawing is feasible,and has practice and theory valuein improving quality and satisfying the need of production

To introduce the application of the technology of deforming with roll forging, design parameter would be gotten by discussing the methods of groove designing about roller die drawing and three roller rolling.
