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.
摘要翻译：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。

摘要： A piercing and rolling plug has a film composed of oxides such as Fe3O4 and FeO and Fe (metal) as being formed on the surface of the base metal by electric arc spraying using an iron wire whose main component is Fe and, owing to this film, a plug excellent in heat-shielding and seizure-preventing effects can be realized and the lifetime of the plug can be prolonged. Further, in regenerating this plug, a film can be re-formed via the steps of shot blasting of the as-used plug in piercing and rolling and electric arc spraying in that order; thus, it is possible to regenerate the plug at low cost and in a short period of time.

摘要： There is provided an antioxidant agent excellent in anti-dripping property and anti-peeling property. The antioxidant agent in accordance with the present invention contains a plurality of glass frits having different softening points, potter's clay, and bentonite and/or sepiolite. On account of the potter's clay, the antioxidant agent applied to the surface of a metallic starting material is less liable to drip down. Further, on account of the bentonite and/or sepiolite, the antioxidant agent is less liable to peel off the surface of the metallic starting material.
