Satellite-mill rolling of U-shaped and H-shaped wires

Abstract The satellite mill with closed pass has been successfully applied to production of U- and H-shaped profiled wires. In this study, the influence of rolling parameters such as the pass schedule, the preform dimensions and the surface roughness of the roll groove has been investigated. It is shown that the satellite-mill rolling can form much higher ribs in products than a conventional method and has an advantage in its ability to fill the metal into roll grooves. This effect is enhanced by rougher grooves and by thicker preforms.
