    Abstract: In applying a non-graphite-based lubricant composed of, by mass %, 10 to 70% of an oxide-based lamellar compound and 30 to 90% of boric acid onto a mandrel bar, the lubricant film thickness is set from a predetermined master curve for the lubricant film thickness corresponding to an amount of mica. This stably produces a seamless steel pipe of high quality, while preventing seizing marks and internal flaws.

    Abstract: Se provee un lubricante para trabajar con plástico caliente, que contiene de 20 a 40% de masa de óxido de hierro y 10 a 30% de masa de silicato de sodio, donde las impurezas son de 3% de masa o menos y el lubricante contiene de 10 a60% de masa de agua. En virtud de la acción combinada de estos componentes, el lubricante exhibe excelente lubricidad y facilidad de suministro y no afecta adversamente a la resistencia a la corrosión del producto. El lubricante es adecuado para usarse para lubricar zapata guía en laminado con perforación, por ejemplo, acero alto en CR y logra un gran efecto para evitar que ocurra una falla por raspamiento en la superficie exterior del producto al ser aplicado directamente a la superficie exterior de una pieza de trabajo justo antes del laminado con perforación, en el lapso de un segundo antes de iniciar el laminado con perforación.

    Abstract: PROBLEM TO BE SOLVED: To provide a hot-rolling lubricant good in workability and excellent in seizure resistance and to provide a method for surface-treating a mandrel bar for the production of hot-rolled seamless pipes using the lubricant.
    SOLUTION: A hot rolling tool lubricant prepared by dispersing or dissolving an oxide-type layered compound such as potassium tetrasilicon mica, sodium tetrasilicon mica, vermiculite, or bentonite, a boric acid compound such as boric acid, potassium borate, or sodium borate, and graphite in water, wherein the mixing ratio of the oxide-type layered compound to the boric acid compound is 10:90 to 70:30 by mass ratio, and the content of the graphite is 1.0-4.5%. When the lubricant is applied to the surface of a mandrel bar during mandrel mill drawing, the lubricant forms a lubricating film on the bar surface and can exhibit excellent seizure resistance. In addition, it does not happen that the lubricant remains on the inside pipe surface.

    Abstract: PROBLEM TO BE SOLVED: To provide a lubricant for hot plastic processing that exhibits excellent lubricity and suppliability and exerts no bad influences on corrosion resistance of a product, and an outer surface-lubricating method in the manufacture of a seamless pipe using the lubricant.
    SOLUTION: The lubricant for hot plastic processing includes 20-40 mass% of iron oxide and 10-30 mass% of sodium silicate and has an impurity content of at most 3 mass% and a water content of 40-60 mass%. The lubricant is suitably applied to lubrication of, for example, a guide shoe at the time of piercing rolling of a high Cr steel. When the lubricant is used, it is directly applied on the outer surface of a material to be processed just before piercing rolling (desirably within 1 second before the beginning of the piercing rolling).
