    Abstract: A system and method for adjusting dipping time in a continuous steel pipe manufacturing line. The system manufactures a steel pipe of which inner and outer faces or any one face thereof is subjected to molten metal-plating from a steel sheet in a continuous manufacturing line, and includes an inner-face plating performing part for molten metal-plating by pouring molten metal to the upper side of the steel sheet corresponding to the inner face of the steel pipe, a steel pipe forming part that obtains a continuous steel pipe by continuously cold-forming the steel sheet subjected to the inner-face plating into a tubular shape and seam-welding a longitudinal end face joint portion of the steel sheet formed in the steel pipe, and an outer-face plating performing part for molten metal-plating by dipping the outer face of the steel pipe into the molten metal, in which a dipping length of the molten metal is adjusted in the inner-face plating performing part and/or the outer-face plating performing part.

    Abstract: A method of making a gun barrel having a breech end and a muzzle end and a bore extending between the two ends comprises applying to the outer surface of the bore a plurality of swaging dies (5), each of which carries an upstanding helical land (10). The dies are pressed simultaneously against the external surface of the gun barrel such that each land forms a helical recess (14) in the external surface and crystalline deformation to the material of the barrel wall immediately below the external helical recess. The distortion of the external surface results simultaneously in the creation of a plurality of smooth helical ridges (16) on the surface of the bore.

    Abstract translation: 制造具有后膛端和枪口端的枪管的方法和在两端之间延伸的孔包括向孔的外表面施加多个模锻模具（5），每个模锻模具（5）承载直立的螺旋状脊 10）。 模具被同时压靠在枪管的外表面上，使得每个焊盘在外表面上形成螺旋形凹槽（14），并在外螺纹凹槽正下方对筒壁材料进行晶体变形。 外表面的变形同时产生在孔的表面上的多个平滑的螺旋脊（16）。
