ができる。BEST MODE FOR CARRYING OUT THE INVENTION In a finishing wire drawing process,
When a wire is drawn using a lubricant in which at least one of oS 2 or WS 2 is uniformly mixed, the viscosity of the semi-solid fat is high, so that the mixed lubricant can be reliably held on the wire surface, and Is semi-solid fat and Mo over time
S 2 and WS 2 are not separated. Therefore, in the finish wire drawing process, the MoS 2 or WS
A semi-solid fat lubricant containing one or more of the two can be applied.

易であるので好ましい。The term "semi-solid fat" refers to grease having a viscosity at 0 to 50 ° C. of 40 to 300 cm 2 / s or a paste-like fat based on animal and vegetable oils, mineral oil and synthetic oil, and has a low viscosity. With the lapse of time, one or more of MoS 2 and WS 2 separate and cannot be uniformly applied to the wire surface. Conversely, if the viscosity is too high, cavities will be formed at places where the wire passes, and it will not be possible to apply the wire to the wire surface. At least one of MoS 2 and WS 2 mixed with the semi-solid fat has an average particle size of 0.5 to 7 μm and a mixing amount of 5 to 5 μm.
0% is preferred because it is easy to adjust the coating amount in the final wire drawing.

する。If the wire surface roughness Ra in the finish drawing step is less than 0.20 μm, a semi-solid oil lubricant containing one or more of MoS 2 or WS 2 is brought in because the wire surface has few irregularities. It is difficult to apply evenly, and the friction resistance of the conduit tube increases during welding, resulting in poor wire feedability. If the wire surface roughness Ra exceeds 0.80 μm, the dies become rough and scratches occur on the wire surface,
The semi-solid fat lubricant containing at least one of MoS 2 or WS 2 is applied too much, and MoS 2 or WS in the next step is applied.
It becomes difficult to adjust the amount of the semi-solid oil lubricant containing at least one of the above-mentioned two types, and the wire slips at the feed roller portion during welding.

に測定した値をいう。The surface roughness Ra of the wire is given by using a roller die having a groove with an appropriate roughness. However, the wire surface roughness Ra has already reached 0.
If it is within the range of 20 to 0.80 μm, it is not necessary to forcibly impart roughness. The wire surface roughness Ra referred to in the present invention refers to a value measured in the longitudinal direction of the wire according to JIS B0601.

と断線を生じる場合がある。[0012] The reduction rate of wire drawing of a die using a semi-solid fat lubricant containing at least one of MoS 2 and WS 2 is 3%.
If it is less than 1, the application amount of the semi-solid fat lubricant containing one or more of the above-mentioned MoS 2 or WS 2 is insufficient because the surface pressure for pressing the die is low, and the adhesion amount of the product wire is small. The friction resistance of the conduit tube increases during welding, and the wire feedability deteriorates. If it exceeds 10%, disconnection may occur.

Cleaning the wire surface with a mixed solution containing 30 to 70%,
By adjusting the application amount of the semi-solid fat lubricant containing at least one of MoS 2 or WS 2 , the semi-solid fat is firmly attached to the wire surface, and at least one of the MoS 2 or WS 2 is evenly dispersed. The wire can be dispersed and held, so that even when a long conduit cable is bent and used at the time of welding, the wire feeding property becomes extremely good.

At the time of welding, the wire slips at the feed roller portion, causing unevenness in the wire feed speed, and an increase in the amount of spatters resulting in an unstable arc. Conversely, if it exceeds 70%,
Semisolid fat wire surface adhesion decreases the Lord is oil too washed MoS to 2 and WS 2 of the wire surface, a die lubricant in the final finishing is insufficient, or cause flaws on the wire surface , MoS 2, or WS 2, the amount of adhesion becomes non-uniform, and the feed resistance in the conduit tube during welding increases, resulting in poor wire feedability. In addition,
Liquid lubricants include animal and vegetable oils such as palm oil, lanolin, and liver oil, mineral oils, and synthetic oils.
It refers to volatile oils such as kerosene, gasoline, and benzene.

The resistance increases and the wire feedability becomes poor. Oil amount 1.00
If it is adjusted to more than g, the wire will slip at the feed roller portion during welding, causing unevenness in the wire feed speed and spatters, resulting in an unstable arc. Adjustment of one or more of MoS 2 or WS 2 on the wire surface and the amount of oil
The mixing can be performed based on the mixing amount of the mineral oil-based cleaning liquid, the length of the cleaning liquid tank installed in the final finishing wire drawing die, the diameter reduction ratio of the final wire drawing, and the like.

１に示す。The present invention will be described in more detail with reference to the following examples. First, the YGW specified in JIS Z3312
A solid wire raw wire of No. 11 and a filling tube of a YFW-C50DR seamless flux-cored wire (flux filling rate of 15%) specified in JIS Z3313 were primarily drawn to a diameter of 3.0 mm in the step shown in FIG. After the annealing, pickling and plating processes, various roughnesses Ra are imparted to the wire surface by roller dies having various roughnesses on the grooves on the inner surface in the middle of the finishing wire drawing process (A to D) (B). Then, wire drawing is applied (C) using a semi-solid lubricant containing at least one of MoS 2 or WS 2 , and final wire drawing (D) is performed.
1. A liquid mixture containing a mineral oil-based cleaning liquid in a liquid lubricant.

表１にまとめて示す。When a load is applied to the wire 8 sent from the spool 2, the wire 8 retreats due to the reaction force of the wire feeding unit 3. The force generated at this time was measured by the load cell 4 as a feeding resistance R. Further, the slip of the wire in the wire feeding unit 3 can be measured by measuring the peripheral speed (TG) of the feeding roller 9 and the passing speed (PG) of the wire by installing the measuring roller 6 at the welding torch 5. The slip ratio was determined by the following equation. Slip ratio = (TG-PG) 100 / TG The feed resistance R within the range where stable welding can be performed is 6 kg.
Below, the slip ratio is also 5% or less. Table 1 also shows the results.
