Description

TECHNICAL FIELD

[0001] The present inventions relates to a belt-shaped lubricating material for dry wiredrawing, which is used for maintaining a stable processing state by preventing seizure due to direct contact between a base material such as a wire material or a rod and a die when the base material is pulled out and reduced in diameter to perform wiredrawing.BACKGROUND ART

[0002] Powdered or granular lubricants for dry wiredrawing are commonly used for wiredrawing processing in which a base material such as a large-diameter wire material or rod made of a metal such as iron and steel or a nonferrous metal is pulled out from a hole of a mold steel such as a die, reduced in diameter into a small-diameter wire material or rod, and plastically deformed. Such a lubricant for dry wiredrawing is used in order to prevent a base material and a die from seizing by coming into direct contact with each other, so that sliding is facilitated to maintain a stable processing state.

Examples

example 1

[0054]In a reaction vessel equipped with a stirrer, 75 parts by weight of industrial stearic acid were heated / melted while being stirred, and 25 parts by weight of slaked lime were then added. Heating / stirring was continued until the mixture became viscous. When the mixture was hardened, heating / stirring was stopped, and the mixture was taken out and cooled, and ground so that the passage rate in a 500 mesh sieve was about 60%, thereby obtaining a calcium-based lubricant as a metal salt of a saturated fatty acid. 70 parts by weight the obtained metal salt of the saturated fatty acid and 20 parts by weight of polyethylene as a thermoplastic resin were heated / kneaded at 180° C. using a heating kneader (trade name: Labo Plasto Mill). The obtained solid was formed into a sheet so as to have a film thickness of 0.5 mm or less using a heating-type press machine, and then cut into a belt having a width of 8 mm using a sheet cutter, thereby obtaining a belt-shaped lubricating material for d...
