In particular, the lubricant composition for processes for producing steel by continuous casting includes a dispersion of a lubricant powder, for an ingot mold, in continuous casting, in an oily liquid means, and a stabilization additive, characterized in that it has the following shear thinning index values:

TABLE-US-00001 RVT 0.1/1 1/10 10/100 100/1000 STI 3.0-7.5 2.0-6.5 1.0-3.0 0.5-2.0 wherein RVT is the ratio between two different shear speeds and STI is the shear thinning index corresponding to the RVT values.

Disclosed is a metalworking oil composition containing: at least one base oil (A) selected from a mineral oil and a synthetic oil; sulfurized oils and fats (B) having a kinematic viscosity at 40° C. of 60 mm.sup.2/s or more and 1,600 mm.sup.2/s or less; and a polymer (C) of an unsaturated fatty acid having a carbon number of 10 or more.

A high viscosity lubricant and dispenser for use in machine work. In one example, the lubricant includes avocado oil and has a viscosity that allows it to be dispensed from a twist-up type, or other suitable dispenser as a paste, gel, or semi-solid. In another aspect, the lubricant includes wax to increase viscosity, the wax may be of any suitable type such as, for example, soy wax.

Provided is a grease composition which is excellent in fire extinguishing performance without water and can suppress fuming, malodor, and liquefaction on burning and a method for producing the grease composition. A grease composition contains a base oil (A), a thickener (B), and a fire retardant (C), wherein the base oil (A) contains a base oil (A1) having a 40° C. kinematic viscosity of 300 mm.sup.2/s or more, a sulfur content of 20 ppm by mass or less, and an initial boiling point of 400° C. or higher, the fire retardant (C) is at least one of aluminum hydroxide (C1) and 1,3,5-triazine-1,3,5 (2H, 4H, 6H)-tris(ethanol) (C2), and a content of the fire retardant (C) is 1.0 to 12.0 mass % based on a total amount of the grease composition.

A method of lubricating metal articles (6), in particular those made of steel, comprising the application (4) of a dispersion comprising a lubricant oil and a lubricant powder to an article to be drawn. A drawing method comprising the lubrication as described above and a lubricant dispersion.

Provided is a heat-treatment oil composition that makes it possible to suppress quenching distortion and distortion variation and to achieve improved quenching hardness. A heat-treatment oil composition that includes a base oil (A) and a vapor film rupturing agent (B). The heat-treatment oil composition makes it such that, on a cooling curve obtained in accordance with the cooling performance test method in HS K2242:2012, the time in seconds to 300 C., e.g., the cooling time from 800 C. to 300 C., is at least 6.5 seconds but less than 10 seconds.
