十分に結合した銅被覆鋼線を得ることができる。[Prior Art] Conventionally, in a method for manufacturing copper-coated steel wire by the so-called dip forming method in which the core material is immersed in molten metal and the coating material is attached, first, the surface of the steel wire that will become the core wire is peeled and then a die or the like is used. to make the surface metallurgically clean. Thereafter, the steel wire is continuously immersed in a molten copper or copper alloy to adhere the copper or copper alloy to the surface of the steel wire and solidify it. Thereby, it is possible to obtain a copper-coated steel wire in which the steel and the copper or copper alloy are sufficiently bonded at the interface between the steel wire and the copper or copper alloy portion.

が多いため、製造コストが高いという問題点もある。[Problem to be Solved by the Invention] However, if the wire diameter and wire speed of the steel wire to be processed are the same, the higher the carbon content of the steel wire, the higher the hardness of the steel wire. The life of the peeling die used in the steel wire surface cleaning process is shortened when manufacturing high-strength copper-coated steel wire. That is, when a steel wire is used as the core material, a large force is applied to the cutting edge of the peeling die during the surface cleaning process, and frictional heat is generated around the cutting edge. While this process is carried out continuously for a long time, the cutting edge of the die gradually wears down, and eventually a part of the steel wire is left uncoated and the copper is not coated in this part. . In this case, it becomes impossible to manufacture copper-coated steel wire, and it becomes necessary to stop manufacturing and replace the die. In this case, there is a problem that the higher the carbon content of the steel wire, the harder the steel wire must be peeled, which shortens the life of the die. Furthermore, since the die must be replaced frequently, there is also the problem that manufacturing costs are high.

The surface of a steel wire containing 0% by weight (but not including 0.1% by weight) and 0.025 to 0.070% by weight of sulfur is ground with a die to be peeled. In this way, by incorporating sulfur into the steel wire, the grindability of the steel wire can be improved. In other words, in the present invention, since it is only necessary to grind the surface layer of the steel wire whose grindability has been improved by incorporating a predetermined amount of sulfur, the force applied to the die is significantly reduced compared to the conventional method. . Thereby, the life of the cutting edge of the die can be extended, and surface grinding and dip forming of the steel wire can be performed continuously over a long period of time.

を得ることができる。Furthermore, since the steel wire used in the present invention has a relatively high carbon content of more than 0.1% by weight and less than 0.50% by weight, the steel wire itself has high strength. In the present invention,
After cleaning the surface layer of the steel wire, which has a relatively high carbon content, by grinding, the steel wire is coated with copper or copper alloy by dip forming, and then, for example, the copper-coated steel wire is subjected to wire drawing. give Thereby, a high-strength copper-coated steel wire can be obtained.

、且つ、炭素含有量が0.1重量%を超える鋼線を使用
すると、炭素含有量が 0.1重量%以下の鋼線を使用

一方、硫黄含有量が 0.070重量%を超えると、伸
線加工性が低下する。[0011] If the sulfur content is less than 0.025% by weight, the effect of improving the grindability of steel wire will not be sufficient. That is, if a steel wire with a sulfur content of less than 0.025% by weight and a carbon content of more than 0.1% by weight is used, a steel wire with a carbon content of 0.1% by weight or less is used. The lifespan of the die will be significantly shortened compared to the normal case. For this reason, the sulfur content of the steel wire is set to 0.025% by weight or more. This improves the grindability of steel wire,
Dice life can be extended. On the other hand, when the sulfur content exceeds 0.070% by weight, wire drawability decreases.

を得ることができない。[0012] Steel wire specified in JIS G 4804 includes free-cutting steel containing 0.08 to 0.40% by weight of sulfur, and free-cutting steel containing 0.08 to 0.40% by weight of sulfur and lead. There are composite free-cutting steels containing 0.10 to 0.35% by weight. However, when these free-cutting steels or composite free-cutting steels are used as copper-coated steel wires, the wire drawability is not satisfactory, and the desired area reduction ratio cannot be obtained during wire drawing.
