Abstract
(EN)
This method for producing a plug used in a piercing mill used in the production of a seamless steel pipe includes: a shot blasting step for shot blasting the surface of a plug; and an arc spray step for forming a coating film by arc spraying a spraying wire at the base material surface of the plug subjected to the shot blasting. The arc spray step performs arc spraying using, as the spraying wire, a cored wire resulting from filling the interior of an iron tube with at least iron oxide particles among iron particles and iron oxide particles (one or more among FeO particles, Fe3O4 particles, and Fe2O3 particles), and a coating film is formed configured from the iron oxide and Fe. As a result, it is possible to produce a piercing plug that can have increased plug production efficiency, stability during piercing, and increased plug life.

Ce procédé pour produire un embout utilisé dans un laminoir perceur pour la production d'un tuyau en acier sans soudure comprend: une étape de grenaillage pour réaliser un grenaillage sur la surface d'un embout; et une étape de projection à l'arc pour former un film d'enrobage par projection à l'arc d'un fil de métallisation à la surface du matériau de base de l'embout soumise au grenaillage. L'étape de projection à l'arc consiste à exécuter une projection à l'arc avec, en tant que fil de métallisation, un fil à âme obtenu par remplissage de l'intérieur d'un tube en fer avec au moins des particules d'oxyde de fer choisies parmi les particules de fer et les particules d'oxyde de fer (une ou plusieurs parmi les particules de FeO, les particules de Fe3O4, et les particules de Fe2O3), et un film d'enrobage est formé qui est constitué d'oxyde de fer et de Fe. Ainsi, il est possible de produire un embout de perçage pouvant présenter un meilleur rendement de production, une meilleure stabilité pendant le perçage et une durée de vie plus longue.

 継目無鋼管の製造に用いられる穿孔圧延機で使用されるプラグの製造方法は、プラグの表面にショットブラストを施すショットブラスト工程と、ショットブラストを施したプラグの母材表面に溶射線材をアーク溶射して皮膜を形成するアーク溶射工程と、を含み、アーク溶射工程では、溶射線材として、鉄粒子、および酸化鉄粒子(FeO粒子、Fe粒子およびFe粒子のうちの一種または二種以上)のうちで、少なくとも酸化鉄粒子が鉄製チューブの内部に充填されてなるコアードワイヤを用いてアーク溶射を行い、酸化鉄およびFeで構成される皮膜を形成する。これにより、プラグの製造能率を向上でき、穿孔圧延時に安定してプラグ寿命を向上できる穿孔圧延用プラグを製造することが可能である。
