Method of manufacturing plug used to pierce and roll metal material, method of manufacturing metal pipe and plug used to pierce and roll metal material
摘要：
A plug material having a prescribed shape is prepared, the prepared plug material is thermally treated in a heat treatment atmosphere that contains at least 1.0 vol. % oxygen at a heat treatment temperature of at least 950° C. and less than 1050° C. and thus a plug having an oxide scale layer 30 on the surface is manufactured. According to the manufacturing method, pores PO that extend along the surface SF of the plug material are formed under outer scale layer 20 in the oxide scale layer 30, which allows cracks to be more easily propagated in the outer scale layer 20. Therefore, the outer scale layer 20 is more easily peeled off than the conventional one.
摘要（中）：

制备具有规定形状的塞子材料，将所制备的塞子材料在包含至少1.0体积％的热处理气氛中进行热处理。 在氧化处理温度为至少950℃且低于1050℃的氧气中制造氧，因此制造了表面上具有氧化皮层30的塞子。 根据制造方法，在氧化皮层30中的外标尺层20上形成有沿插塞材料的表面SF延伸的孔PO，这允许裂纹在外标尺层20中更容易传播。因此， 外标层20比常规剥离更容易。
