Abstract: By using a piercing mill that includes a pusher on the entrance side, a plug on the exit side along a pass line, and a plurality of angled rolls as being provided around the plug so as face to each other, in the case where the maximum diameter of an unsound region consisting of center segregation and porosity in a cross section of a billet is d [mm], piercing-rolling is performed under the condition that the plug nose rolling reduction ratio (TDF) expressed by Formula (1) satisfies Formula (2). TDF=(Bd?D1)/Bd??(1) TDF??0.50×(d/Bd)+0.06??(2) In Formulae (1) and (2), Bd is the billet diameter [mm], and D1 is the opening [mm] between the angled rolls at the plug nose position.

Abstract: A method for producing a plug for use in a piercing-rolling mill for producing a seamless steel tube/pipe includes a step of carrying out shotblasting on a surface of the plug, and an arc-spraying step of performing arc-spraying of a spray wire 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, arc-spraying uses a cored wire whose iron sheath tube is filled with at least low-thermal conductive particles like ZrO2 particles, which have lower thermal conductivity than that of iron oxide among iron particles and low-thermal conductive particles, to form the film containing iron oxide, Fe and low-thermal conductive material. The formed film has enhanced insulation performance to produce the plug capable of ensuring the steady enhancement of the durability life of the plug during the piercing-rolling.

Abstract: A lubricant for hot-rolling tools in which an oxide-based laminar compound such as potassium tetrasilicic mica, sodium tetrasilicic mica, vermiculite, and bentonite, a boric acid compound such as boric acid, potassium borate, and sodium borate, and graphite are dispersed and dissolved in water, and in which the blending proportion of the oxide-based laminar compound to the boric acid compound is, in mass ratio, 10:90 to 70:30, and the content of the graphite is 1.0 to 4.5%. Applying this lubricant on the surface of the mandrel bar at the time of mandrel mill rolling enables a lubricating film to be formed on the surface of the bar and to exert excellent seizure resistance, and also allows the lubricant to be immune from remaining in the inner surface of tube.
