Four methods that may be applied for steel wire strengthening and toughening are discussed in this paper, they are, microalloying, thermal deformation by roll drawing, equal channel extrusion and electric pulse treatment.

The installation and lifetime of roller and effect of roll drawing on mechanical property is illuminated.

Thermal-structure coupling analysis of pulling-straightening roller using ANSYS software;

To improve the service life of the pulling-straightening roller in CCM, a new-type compound roller is proposed in this pa- per.

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
