    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 machining oil for brittle materials, the slurry of which can be supplied sufficiently to a machining space and which includes excellent machining properties.
    SOLUTION: The machining oil for brittle materials is obtained by blending (a) base oil, (b) a nonionic surfactant, which is an alkylene oxide adduct of polyhydric (dihydric to hexahydric) alcohol and includes 2-50 molar number of the added alkylene oxide, and/or another nonionic surfactant, which is a derivative of the alkylene oxide adduct of polyhydric (dihydric to hexahydric) alcohol and includes 2-50 molar number of the added alkylene oxide, and (c) bentonite. The content of the (b) component is 0.2-30 mass% and that of the (c) component is 0.1-10 mass% on the basis of the whole mass of the machining oil.
