いられている。2. Description of the Related Art There is a remarkable increase in wire drawing speed in wire drawing, and high-speed wire drawing is performed at a speed of one thousand and several hundred m / min. 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 of the lubricant is very large. Lime soap is positioned as a pretreatment agent together with phosphate and borax in the lubricant treatment of wire drawing work, and is used as a lubricant carrier in the processing of steel materials with a relatively low carbon content (appropriate unevenness on the material surface). It is used together with a dry lubricant as a component that has the effect of carrying in the lubricant by giving the effect of preventing the contact between metals (Tri).
Biology Metalworking J. A. S
hey, P385, ASM. (1983), "Lubricant Manual for Iron and Steel Wire Drawing" edited by Japan Society of Plastic Processing, Wire Drawing Technology Subcommittee, Lubricant Subcommittee, P18 (1982)). Lime soap is relatively inexpensive, is useful as a temporary rust preventive, and is used as a neutralizing agent for a pickling solution used in pretreatment. Since the residual film after drawing is easy to remove, and it shows a certain degree of lubricity even by itself, it is used without a dry lubricant for light processing. Its history goes back to the early Showa era, but it is still widely used due to its many advantages.

らず、製法や使用方法が記載されている程度である。However, although it has such a long history, its own lime soap is actually produced by a method based on many years of experience in improving wire drawing. ("Lubricant manual for steel wire drawing", p19). The reason is that 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 the literatures in the past have not even defined a clear definition of lime soap, and only the manufacturing method and usage method are described.

可逆的に起きると考えられている。[0004] For example, the manufacturing method is described in "Lubricant Manual for Iron and Steel Wire Drawing" edited by Japan Society for Plastic Working, Wire Drawing Technology Subcommittee. According to this, when an excess amount of quick lime (calcium oxide) is added to alkali soap and stirred in water, first, slaked lime (calcium hydroxide) is generated by the digestion (hydration) reaction of quick lime according to the reaction formula (1). It is believed that the heat generated at this time causes a metathesis reaction between slaked lime and soap according to the reaction formula (2), and the reaction of the reaction formula (2) occurs reversibly.

触を防止する役割も有している。Therefore, the lime soap thus produced contains slaked lime, calcium soap and alkali produced, unreacted alkali soap which did not become calcium soap, and water. Of these, slaked lime and calcium soap, which are the main components, are adsorbed on the processed material in the lubricant composition and retain the lubricant (carrier effect).
Along with this, calcium soap has a role to reduce the friction coefficient of lime soap (sliding effect), and slaked lime also has a surface roughness to hold the lubricant and also has a role to prevent metal-to-metal contact during processing. ing.

００１記載の生石灰特号が使用されている。Lime soap varies depending on the purpose of use,
As a standard method in the "Lubricant Manual for Steel Wire Drawing", 5 to 10 parts by weight of alkaline soap of fatty acid and about 400 parts of water are added to 100 parts by weight of quick lime. It describes a method of adding ˜3 times the amount of water and allowing it to stand. The raw materials used are fatty acid alkali soap, quicklime, and water. Alkaline salts of sodium, potassium, etc. are used for the alkaline soap of fatty acid, but generally needle-shaped alkaline soap of beef fatty acid is often used. Quicklime is JIS-R9 as described in "Lubricant Manual for Steel Wire Drawing".
The quicklime special number described in 001 is used.

されている。As a general lubricant treatment method, the wire is pickled with hydrochloric acid or sulfuric acid, chemically descaled, and then washed with water at a temperature of 50 to 60 ° C. and a concentration of 5 to 30% by weight. It is dipped in lime soap of a certain degree 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-shaped hanger and immersed in a batch system. After forming a lime soap film and drying, it may be immediately drawn, but in some cases it may be left in the factory for about a week. Wire drawing is performed as it is, or depending on processing conditions, a dry lubricant such as metal soap powder or an oil-based lubricant is applied to perform wire drawing.

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

上、線材結束部という）で見られる。The above-mentioned conventional technique has the following problems. When using lime soap, you must avoid mixing pickling solution. ("Lubricant Manual for Iron and Steel Wire Drawing" p19) Even after a normal finish immediately after lime soap treatment, rust occurs on the surface of the wire material under the lime soap coating after several days. This is caused by the effect of the pickling solution component because the washing with water after pickling is insufficient. To prevent this, sufficient washing with water may be performed. However, when the coil-shaped wire is hung on a C-shaped hanger and treated by a dipping method in a batch method, rust may occur immediately after the lime soap treatment. This phenomenon can be seen in a portion where the wire is bundled (hereinafter, referred to as a wire binding portion for convenience) when the coiled wire is processed, especially 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 action different from the rust generation described in the "Lubricant Manual for Iron and Steel Wire Drawing", and cannot be solved by sufficiently performing water washing after pickling. The measures are taken empirically. For example, methods such as increasing the concentration of lime soap and performing immersion treatment several times are used. What can be said in any of the cases is that if rust is generated on the surface of the wire, it will be the starting point while being left standing and the rust surface will further spread. As a result, the lubricating performance of lime soap is significantly reduced. In addition, lime soap is often required to have uniformity and gloss on the surface of the finished line, which is an important item when selecting lime soap.

It was found that the rust-preventing property of the wire-bonded portion, the uniformity of the finished surface, and the glossiness are improved without impairing the above, and the present invention has been completed.

The property 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. On the contrary, it is not preferable from the viewpoint of lubricating performance that the content of the saturated fatty acid becomes high when the number of carbon atoms is less than 16.

成する。Next, the method for producing lime soap of the present invention will be described. In practice, the same production method as in the past may be used, but an alkaline soap of 10 to 30% by weight of fatty acid relative to the weight of quicklime is added to water for production. The reaction temperature at the time of production must be higher than the melting temperature of the alkaline soap of the fatty acid used. That is, the alkali soap dissolves due to the rise in water temperature due to the digestion of quicklime, and the reaction of the reaction formula (2) proceeds, but the alkali soap of a fatty acid tends to have a higher dissolution temperature in water as the carbon number thereof increases. is there. In order to adjust the temperature during the reaction to the melting temperature of the alkaline soap of fatty acid to be used, it is necessary to consider the ratio of quick lime and water, or to raise the water temperature in advance by a heating device. When the soap reaches a temperature at which it 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。By using the lime soap of the present invention, the rust preventive property at the binding portion of the wire is improved, and at the same time, the uniformity and gloss of the finished wire surface are improved. As for rusting at the wire binding part, the binding of the wire binding part becomes stronger due to the weight of the wire itself,
It occurs because the pickling solution becomes difficult to remove. It is considered that by containing an appropriate amount of unsaturated fatty acid, the lime soap presents a surfactant, the lime soap solution is easily immersed in the wire binding portion, and the pickling solution is neutralized.

した。同様の方法にてアルカリ分を算出した。[Calculation Method of Lime Soap] To the produced lime soap, approximately the same amount of ethanol water (50% by volume) is added and stirred at 50 ° C. for about 30 minutes. Alkaline soap is dissolved in ethanol and separated into an ethanol water-soluble component and an ethanol water-insoluble component using a filter paper. The components that are filtered at this time are alkali and alkaline soap, and the components that are not filtered are calcium soap and slaked lime. A suitable amount of hydrochloric acid was added to these isolates to acid-decompose them to obtain a fatty acid, which was dissolved in diethyl ether, and the fatty acid contained in the ethanol-water-soluble component and the ethanol-water-insoluble component was quantified by gravimetric measurement. . Subsequently, the calcium content in the ethanol-water insoluble component and the sodium content in the soluble component were quantified by an atomic absorption method. Further, the calcium soap content was calculated from the average molecular weight of the fatty acid composition in Table 1 and the fatty acid content in the ethanol insoluble component, and the sodium soap content was calculated from the fatty acid content in the ethanol insoluble component.
The calcium content forming calcium soap was subtracted from the calcium obtained by atomic absorption to calculate the slaked lime content. The alkali content was calculated by the same method.

る。The results of the above evaluations are summarized as follows. The lubricant composition of the present invention has the uniformity of the finished line surface,
The glossiness has a composition that imparts appropriate peelability and is resistant to seizure. In Example 4, although there was rusting at several places in the wire binding portion, it is considered that the die life of 10 tons or more was exhibited because sodium soap of constituent fatty acid having a large number of saturated fatty acids having 18 carbon atoms was used. The lubricant composition of Comparative Example 1 had too much residual film after wire drawing, and Comparative Examples 2 to 5 were considered to have failed to obtain uniformity and glossiness of the finished line surface because seizure occurred. To be The lubricant composition of Comparative Example 1 exhibited a very good carrier effect in a test with a small amount of wire rod, but when treated in a coil form, many rusts were generated at the wire rod binding portion, and the die life was extremely short. From this, it is clear that the die life is greatly affected by rusting at the wire binding portion.
