摘要： There is provided a lubricant for hot plastic working, which contains 20 to 40 mass% of iron oxide and 10 to 30 mass% of sodium silicate, wherein impurities are 3 mass% or less, and the lubricant contains 40 to 60 mass% of water. By virtue of combined action of these components, the lubricant exhibits excellent lubricity and suppliability and does not adversely affect the corrosion resistance of product. The lubricant is suitably used for lubricating a guide shoe in piercing-rolling, for example, a high-Cr steel and achieves a great effect of preventing a seizure flaw from occurring on the outer surface of product by being applied directly to the outer surface of a workpiece just before piercing rolling, preferably, within one second before starting piercing rolling.

摘要： A process for stainless-steel pipe production which comprises piercing and rolling a raw material stainless steel containing, by mass, Cr: 10-30%, to give a hollow shell, elongating rolling the hollow shell using a mandrel bar, together with a graphite-free lubricant, to give a finishing rolling blank pipe and heating the blank pipe in a reheating furnace and subjecting the same to finishing rolling by sizing rolling to produce a hot-finished pipe, and then subjecting this pipe as a mother pipe to cold working to produce a stainless-steel pipe. In the reheating furnace, the finishing rolling blank pipe is heated to 1000°C or more and subjected to heating in which an oxidizing gas is blown into the pipe inside, whereby a stainless-steel pipe which is inhibited from forming a carburized layer in the pipe inner surface can be produced. When the finishing rolling by sizing rolling to give a cold working mother pipe is carried out by stretch reducer rolling at 860-1050°C, an annealing heat treatment of the mother pipe for cold working can be omitted. Thus, a stainless-steel pipe having excellent surface quality can be efficiently produced.

摘要： It is an object of the present invention to provide a mandrel bar cleaning facility capable of effectively suppressing carburization generated on the inner surface of a pipe or tube while the pipe or tube is elongated and rolled without hindering an operation. A mandrel bar cleaning facility 15 of the present invention cleans a mandrel bar B which is pulled out of a mandrel bar conveying line after being used for elongating and rolling a pipe or tube in a mandrel mill 8. The mandrel bar cleaning facility 15 is provided with conveying devices 17, 18 that convey the mandrel bar B in the axial direction while revolving the mandrel bar B in the peripheral direction, and cleaning devices 1d that are arranged oppositely to the side of the mandrel bar B conveyed by the conveying devices 17, 18, and jet high-pressure water having a water pressure of 0.2 to 150 MPa (preferably, 20 to 150 MPa) toward the outer surface of the mandrel bar B.

摘要： When performing piercing-rolling by use of a plug with a protection film on its surface, applying a lubricant made of an aqueous solution containing a total of 5 to 30% mass% of one or more of boron oxide, boric acid, and amine borate to the protection film on the plug surface, and using this plug for piercing-rolling makes it possible to realize the increase of the life of plug for piecing-rolling without reducing the efficiency of piercing-rolling, consequently allowing the efficient production of a seamless steel tube/pipe. Moreover, it is preferable that the plug is cooled after the piecing-rolling, the application of the above described lubricant is performed when the surface temperature of the front edge of plug decreases to 100°C or less, and the plug is reused for the piercing-rolling. In this occasion, it is preferable that the protection film on the plug surface is formed by arc spraying iron wire material onto the surface of the base metal of plug, and comprises oxides and Fe.
摘要翻译：当在其表面上使用具有保护膜的塞子进行穿孔轧制时，涂布由含有总计为5〜30质量％的氧化硼，硼酸和硼酸胺中的一种或多种的水溶液制成的润滑剂对于插头表面上的保护膜，并且使用该插头进行穿孔轧制，可以在不降低穿孔效率的情况下实现用于接头轧制的插头的寿命的增加，从而允许有效地生产无缝钢管/管。此外，优选的是，在接头轧制之后将塞子冷却，当塞子的前端的表面温度降低到100℃以下时，执行上述润滑剂的应用，并且将塞子重新用于穿孔轧制。在这种情况下，插塞表面上的保护膜最好是通过将铁丝材料电弧喷镀到塞子的母材表面上，并且包含氧化物和Fe。
