いられている。2. Description of the Related Art There has been a remarkable increase in the drawing speed in wire drawing, and a high-speed drawing of several hundreds of meters / minute has been performed. It is said that this is due not only to advances in wire drawing equipment but also to advances in lubrication technology.
It can be said that the role played by the lubricant is very large. Lime soap is regarded as a pre-treatment agent along with phosphate and borax in the lubricant treatment of wire drawing, and is used as a carrier for lubricant in the processing of steel with a relatively low carbon content. Is used together with a dry lubricant as a component (having an effect of carrying a lubricant by imparting the same and preventing contact between metals).

hey, P385, ASM. (1983), "Lubricant Manual for Wire Drawing of Steel", edited by the Subcommittee for Lubricants, Subcommittee of the Japan Society for Technology of Plasticity, P18 (1982)). Lime soap is relatively inexpensive, is also useful as a temporary rust inhibitor, and is used as a neutralizing agent for pickling liquids used in pretreatment. Since the residual film after the drawing is easily removed and shows a certain degree of lubrication even when used alone, it is used without a dry lubricant in the case of light machining. Although its history dates back to the early Showa era, it is still widely used today due to its many strengths.

らず、製法や使用方法が記載されている程度である。[0003] In spite of such a long history, unique lime soap is actually produced by a method based on many years of experience in improving wire drawing. ("Lubricant manual for steel drawing", p19). It is necessary to properly use the performance of the lubricant to be used depending on the purpose (Lubrication, Nobuhiro Yoshida, 30, 709 (1985)), but there is still little universal knowledge about lime soap. Seems like one of the factors. Even in the past literature and the like, a clear definition of lime soap is not even defined, and only the production method and usage method are described.

According to this, when excess lime (calcium oxide) is added to an alkali soap and stirred in water, slaked lime (calcium hydroxide) is generated by a digestion (hydration) reaction of quick lime according to the reaction formula (1). It is considered that slaked lime and soap undergo a metathesis reaction by the reaction formula (2) due to the heat generated at this time, and the reaction of the reaction formula (2) occurs reversibly.

触を防止する役割も有している。[0006] The lime soap thus produced contains slaked lime, calcium soap and alkali formed, unreacted alkali soap which has not been converted into calcium soap, and water. Of these, slaked lime and calcium soap, which are the main components, are adsorbed to the work material in the lubricant composition and hold the lubricant (carrier effect).
Calcium soap also has the role of reducing the friction coefficient of lime soap (slip effect), and slaked lime gives the surface roughness to hold the lubricant and also has the role of preventing metal-to-metal contact during processing ing.

As a standard method, "lubricant manual for steel drawing" adds 5 to 10 parts by weight of an alkali soap of a fatty acid and about 400 parts of water to 100 parts by weight of quick lime. It describes a method of adding up to three times the amount of water and leaving it to stand. The raw materials used are alkaline soaps, quicklime and water of fatty acids. Alkali salts such as sodium and potassium are used for fatty acid alkaline soaps, and needle-like alkaline soaps of bovine fatty acid are generally used. Quicklime is JIS-R9 as described in the “Steel Wire Drawing Lubricant Manual”.

されている。As a general lubricant treatment method, the wire is pickled with hydrochloric acid, sulfuric acid or the like, chemically descaled, washed with water, and at a temperature of 50 to 60 ° C. and a concentration of 5 to 30% by weight. The lime soap is immersed in lime soap and dried to form a lime soap film. In these treatments, a coil-shaped wire rod of about 1 ton is hung on a C-type hanger and immersed in a batch system. After a lime soap film is formed and dried, wire drawing may be performed immediately, but in some cases, it may be left in a factory for about one week. The wire drawing is performed as it is or depending on the processing conditions, a dry lubricant such as a metallic soap powder or an oil-based lubricant is applied.

の役割を果している。[0009] Lime soap is also used for wire drawing of bearing steel and the like. In this process, the steel wire is subjected to a phosphate treatment and then a lime soap treatment. In this case, the lime soap plays a role not as a carrier but as a component that gives slipperiness.

("Lubricant Manual for Iron and Steel Wire Drawing" p19) Immediately after the lime soap treatment, even if the finish is normal, rust is generated on the surface of the wire under the lime soap film after several days. This is caused by the effect of the pickling solution component because the water washing after the pickling is insufficient. In order to prevent this, sufficient washing may be performed. However, if the coiled wire is hung on a C-type hanger and treated in a batch method by an immersion method, rust may be generated immediately after the lime soap treatment. This phenomenon is observed at a bound portion (hereinafter referred to as a wire binding portion for convenience) when processing a coiled wire, particularly when the wire diameter is small.

んを選定する場合の重要な項目である。This phenomenon is caused by an effect different from the generation of rust described in the "Manual for Lubricating Lubricants for Iron and Steel Wires", and cannot be solved by sufficiently washing with water after pickling. The measures are taken in an empirical way. For example, a method of increasing the concentration of lime soap or performing immersion treatment several times has been adopted. What can be said in any case is that when rust is generated on the surface of the wire, this becomes a starting point while the wire is left, and the rust surface further spreads. As a result, the lubrication performance of lime soap is significantly reduced. Lime soap often requires uniformity and gloss on the surface of the finished line, which is an important item when selecting lime soap.

Further, when the unsaturated fatty acid having 18 carbon atoms exceeds 40% of the total amount of the constituent fatty acids, the rust-preventing property of the wire bundle is improved, but the carrier effect is reduced, so that metal-to-metal contact occurs. It becomes easy and seizure occurs. If many scratches occur, the gloss decreases.

The performance is improved. Among saturated fatty acids having 16 or more carbon atoms, it is more preferable that the content of fatty acids having more carbon atoms is high. Conversely, an increase in the content of the saturated fatty acid below 16 carbon atoms is not preferable from the viewpoint of lubrication performance.

成する。Next, the method for producing lime soap of the present invention will be described. In the practice, the same production method as in the related art may be used, but the production is performed by adding 10 to 30% by weight of an alkali soap of a fatty acid to water based on the weight of quicklime. It is necessary that the reaction temperature at the time of production be equal to or higher than the dissolution temperature of the alkali soap of the fatty acid used. That is, alkali soap dissolves due to an increase in water temperature due to the digestion of quick lime, and the reaction of reaction formula (2) proceeds. However, the alkali soap of fatty acids having a higher carbon number tends to have a higher dissolution temperature in water. is there. In order to make the temperature at the time of reaction equal to or higher than the dissolving temperature of the alkaline soap of the fatty acid to be used, the ratio of quick lime and water must be considered, or the water temperature must be raised in advance by a heating device. When the temperature reaches the temperature at which the soap dissolves in water, the metathesis reaction proceeds and calcium soap is produced.

り、酸洗液が中和されると考えられる。The use of the lime soap of the present invention improves the rust prevention at the wire binding portion, and also improves the uniformity and gloss of the finished wire surface. Rust at the wire binding part becomes stronger at the wire binding part due to the weight of the wire,
This occurs because the pickling liquid is difficult to remove. It is considered that the lime soap presents a surfactant by containing an appropriate amount of unsaturated fatty acid, so that the lime soap solution is easily immersed in the wire bundle portion, and the pickling solution is neutralized.

沢性が得られると考えられる。On the other hand, a decrease in the uniformity and gloss of the finished wire surface can be interpreted as a phenomenon that occurs due to an excessive amount of the residual film after the wire drawing process (“lubricant manual for steel wire drawing”, p. 64). It is also considered that by containing an appropriate amount of unsaturated fatty acid, the lime soap film is given an appropriate peeling property and gloss is obtained.

る。The above evaluation results are summarized as follows. The lubricant composition of the present invention has a uniform finish line surface,
The gloss imparts a suitable releasability and has a composition in which seizure hardly occurs. In Example 4, rusting occurred at several places at the wire binding portion, but it is considered that a die life of 10 tons or more was exhibited because sodium soap as a constituent fatty acid having a large number of saturated fatty acids having 18 carbon atoms was used. It is considered that the lubricant composition of Comparative Example 1 had too much residual film after wire drawing, and that Comparative Examples 2 to 5 did not have uniformity and glossiness of the finished wire surface because seizure occurred. Can be The lubricant composition of Comparative Example 1 showed a very good carrier effect in a test using a small amount of wire, but when it was processed in a coil shape, a large number of rusts occurred at the wire binding portion and the die life was extremely short. From this, it is clear that rust at the wire binding portion has a large effect on the die life.
