摘要： PROBLEM TO BE SOLVED: To perform accurate molding into a cylindrical shape without lubrication by using a large diameter roll stand in which rolls having diameters clearly larger than the outer diameter of a pipe to be molded are arranged so as to manufacture a small diameter welded pipe with good production efficiency.SOLUTION: The roll stand including a pair of right and left side rolls is used. The roll stand uses the large diameter side rolls which are designed so that the outer diameter ratio φ/φof the outer diameter φof the molding roll to the outer diameter φof the pipe to be molded is 10 or larger, as the pair of side rolls. After a metal band is molded into a cylindrical shape through the roll stand in a single stand, abutment portions of edges of the metal band are welded and joined to each other. A three roll-type or a four roll-type can be used as the large diameter side roll. Since manufacturing in the single stand is enabled, this can reduce labor and time for roll exchange, so as to contribute to cost reduction.
摘要翻译：要解决的问题：通过使用其中布置有直径明确大于待模制管的外径的辊的大直径辊架来进行精确的模制成圆柱形而不进行润滑，以便制造小型直径焊管，生产效率好。
解决方案：使用包括一对左右侧辊的辊架。辊架使用大直径侧辊，其设计成使外径比φ 2 /Φ 1 成型管的直径Φ 2 为待成型管的外径φ 1 ，为10以上一对侧卷。在金属带通过辊架在单个支架中成型为圆柱形形状之后，金属带的边缘的邻接部分被焊接并彼此接合。可以使用三辊式或四辊型作为大直径侧辊。由于可以在单台架上进行制造，因此可以减少轧辊交换的人力和时间，从而有助于降低成本。版权所有（C）2013，JPO＆INPIT
