Abstract
PURPOSE:To exactly guide the rolled material to the roll of the piercing mill, by installing the grooved roll, for guiding the corner edge part of the rolled material, so as to be movable in the direction of diagonal of the section of rolled material. CONSTITUTION:In the piercing mill, where the rolled material 1 is pierced by the plug bar while being rolled by the upper and lower rolls, the guide is constituted of the grooved roller 6, the roller holder 9, the roller shaft 8, and the slide box 10. The roller holder 9 is guided in the slide box 10 by the worm 11, worm wheel 12, and the screw shaft 13, so as to go and back in the diagonal direction of the rolled material 1. This movement is transmitted to the grooved roller 6, which is then moved in the diagonal direction of the rolled material 1. According to this method, the wall thickness of the rolled product 1 is exactly made uniform, and the hollow pipe can be manufactured with almost no thickness deviation.
