摘要： Provided is a method for producing a plug for use in a piercing-rolling mill for producing a seamless steel tube/pipe, and the method for producing the plug includes a shotblasting step of carrying out shotblasting on a surface of the plug, and an arc-spraying step of performing arc-spraying of a spray wire so as to form a film on a surface of a base metal of the plug to which the shotblasting is applied. In the arc-spraying step, the arc-spraying is carried out by using, as the spray wire, a cored wire whose iron sheath tube is filled with at least low-thermal conductive particles (e.g. ZrO 2 particles) having lower thermal conductivity than that of iron oxide among iron particles and low-thermal conductive material, so as to form the film containing iron oxide, Fe and low-thermal conductive particles. Accordingly, it is possible to form the film having enhanced insulation performance, and to produce the plug capable of ensuring the steady enhancement of the durability life of the plug during the piercing-rolling.

摘要： Provided is an equipment system for producing a piercing-rolling plug to be used for producing a seamless steel tube/pipe, which includes a shotblasting device for applying shotblasting on a surface of the plug, and an arc-spraying device for performing arc-spraying of iron wires on a surface of a base metal of the plug to which the shotblasting is applied, so as to form a film containing oxide and Fe thereon. The arc-spraying device includes plural spraying booths each of which separately forms part of the film in turn in each of sections into which the surface of the base metal of the plug is divided along an axial direction of the plug. The production efficiency of the plug can therefore be maintained at a high level, and steady enhancement of the durability life of the plug can be realized during the piercing-rolling.

摘要： A method for producing a plug includes: a step of preparing a plug base metal (10) having a concave portion (11z) along a circumferential direction in an outer peripheral surface (11); and an arc spraying step of spraying a spraying wire rod material onto the outer peripheral surface (11) of the plug base metal (10) by arc spraying to form films (20a and 20b) containing Fe and Fe oxides on the outer peripheral surface (11) of the plug base metal (10). The arc spraying step includes: a separating step of separating the outer peripheral surface (11) of the plug base metal (10) into a plurality of regions (S1 and S2) along an axial direction; and a step of performing arc spraying separately in each of the regions (S1 and S2). In the separating step, a boundary between the regions (S1 and S2) is set at the concave portion (11z). In this way, peeling of films at a connecting portion is prevented, and the lifetime of the plug can be increased.
