摘要： A piercing mill includes a plurality of inclined rolls, a plug, a pusher, and an undriven guide roll. The pusher pushes a round billet from the rear end at least until the round billet advances for a prescribed distance after contacting the inclined rolls. The guide roll is between the inclined rolls and the pusher and includes a roll shaft and a roll surface, with the roll shaft arranged obliquely with respect to a pass line PL. The sectional shape of the roll surface is a concave arch shape. The round billet is rotated by the guide roll and the friction force generated when the round billet contacts the inclined rolls is reduced. Consequently, the wear of the inclined rolls can be restrained if the round billet is pierced and rolled while it is pushed in between the inclined rolls using the pusher.
摘要翻译：穿孔机包括多个倾斜辊，塞子，推动器和未驱动的引导辊。推动器从后端推动圆钢坯至少直到圆钢坯在接触倾斜辊之后前进一段规定的距离。引导辊位于倾斜辊和推动器之间，并且包括辊轴和辊表面，辊轴相对于通过线PL倾斜布置。辊表面的截面形状是凹拱形状。圆钢坯被导向辊旋转，并且当圆钢坯接触倾斜辊时产生的摩擦力减小。因此，如果圆钢坯在使用推动器推入倾斜辊之间的同时被冲压并滚动，则可以抑制倾斜辊的磨损。

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.

摘要： A plug includes a front edge portion having a convex curvature; a cylindrical portion having a truly or nearly cylindrical shape; a trunk portion having an outer diameter gradually increasing toward a rear edge thereof; a mandrel joint provided in a rear edge portion of the plug; a lubricant ejection hole running through the trunk portion from the mandrel joint that opens on the surface of the cylindrical portion; and a coating comprising oxides and Fe that is formed on the base metal surface of each of the front edge portion as well as the trunk portion by arc spraying using an iron wire. In this way, the plug can prevent inner surface flaws from occurring in a hollow blank that is deformed by piercing-rolling, and can extend its life without requiring a long time for making it.
