Conventionally, lubricant compositions of this type include lubricating oils, greases, or mixtures thereof with solid lubricants such as graphite powder and tungsten disulfide, or alkali metal sulfates, borates, potassium chloride, ), graphite powder and a must! It is known that an aqueous dispersion of a fine powder mixture containing an auxiliary agent added by the above is used. However, in the former case, the oil is thermally unstable and decomposes during use, causing negative effects on tools and workpieces, and the oil and oil decomposition products significantly contaminate the working environment. Furthermore, the latter method (1) cannot be said to exhibit satisfactory lubrication performance, particularly in the production of rimless steel pipes.

In the present invention, □ Since the animal protein itself has the function of dispersing graphite powder, the use of a dispersant is not necessarily necessary, but when using an animal protein that can be dispersed in water and is It is preferable to use a dispersant. This-
The dispersant used for this purpose is one that is soluble in water or has water-suspending properties, has a thickening effect and an adhesive effect, and has a dispersing action that prevents the graphite powder from settling. Examples of dispersants that may be used include natural adhesive dispersants such as carboxymethyl cellulose and starch, polysaccharides such as bolytichalide, adhesives such as guar gum, synthetic adhesive dispersants such as bobbinyl alcohol, and polyoxyethylene. Examples include surfactants such as alkyl ethers. In addition, some animal proteins deteriorate if left for a long period of time, so it is preferable to use a preservative such as ethyl paraoxybenzoate.

The high-temperature lubricant composition of the present invention is used as an aqueous lubricant dispersion by dispersing carbon in water, and the solid fraction concentration at this time is usually 5-SS weight-1, preferably 10 to Adjust to within a range of 30% by weight. If this solid content concentration is too thin, the drying time will be longer and the thickness of the formed film will become thinner, making it impossible to obtain good lubrication performance. The method of using the aqueous lubricant dispersion prepared in this way is to apply the lubricant aqueous dispersion to the surface of the metal to be hot-processed, to mandrels, dies, etc.
It is applied to the surface of a tool such as a roll by a conventional means, and is dried to form a coating on the surface of these metals or tools, followed by hot working.
