設けている。Conventionally, known methods for manufacturing aluminum-coated wire rods, especially steel wires, include plating, powder sintering, rolling, extrusion, cladding, and wire drawing.In particular, powder sintering and rolling methods were developed by Copperweld Co., Ltd. in the United States. This development is extremely effective for the mass production of high-quality composite wires. In this method, aluminum powder is pressed onto a steel wire using 40,000 rolls, and after heating and sintering, re-rolling and wire drawing are repeated to provide an aluminum coating.
しかしながらアルミニウム粉末は人気中では爆発の危険
性があるためにその取扱いに充分な注意が必要であり、
更に非酸化性雰囲気での圧着、焼結を行う必要がある。However, due to the danger of explosion when aluminum powder is popular, it is necessary to be careful when handling it.
Furthermore, it is necessary to perform compression bonding and sintering in a non-oxidizing atmosphere.
また接着性を増すために大きな圧下率および伸線加工率
を与える必要があるために製造工程が長く、設備占有面
積が大となる。In addition, since it is necessary to apply a large rolling reduction and wire drawing processing rate to increase adhesiveness, the manufacturing process is long and the equipment occupies a large area.

製造する方法を提供することである。The purpose of the present invention is to solve the drawbacks of the danger of explosion of aluminum powder and the equipment occupation area in the conventional powder sintering and rolling methods, and to provide a high-quality, especially ultra-thin aluminum coating with safety and a relatively small equipment occupation area. An object of the present invention is to provide a method for manufacturing a composite wire.

の均一付着を達成するに必要である。FIG. 1 conceptually shows an apparatus for carrying out the method of the present invention for manufacturing composite steel wire, in which a delivery device 110 is shown.
The steel wire 1 from the above firstly increases production speed and improves adhesion. Mechanical polishing is performed by a polishing device 11 to sufficiently activate the surface of the steel wire. Polished steel wire
After the dirt on the surface is removed by the cleaning device 12, the aluminum powder with a particle size of 325 mesh or less is placed in an aqueous solution that does not contain any adhesive or adhesive other than a small amount of slurry stabilizer to prevent corrosion of the wire. The water is passed through a suspension tank 13 in which the water is suspended in water. Limiting the particle size of the aluminum powder in the suspension tank 13 is necessary to achieve uniform adhesion of the aluminum powder to the wire surface.

造出来る。The wire to which the aluminum powder is evenly adhered is heated by the heating device 14.
After being preliminarily heated, the wire is rolled by a rolling roll 15 to press the aluminum 9m onto the surface of the wire. Due to this preheating, a rolling reduction ratio of several percent is sufficient. The roll groove shape of the nine rolling rolls 15 is relatively difficult to enter, and it is conceivable to increase the number of rolling cycles. In the present invention, in order to avoid an increase in the occupied floor area due to an increase in the number of rolling stages, the wire drawing die 17 is heated again after rolling using the heating device f#16.
After drawing the wire using a wire, the wire is wound onto a reel 18. By doing so, a composite steel wire having an extremely thin aluminum coating can be manufactured using a relatively small floor space and small-scale equipment.

This suspension tank 13 has a diameter of 4
．． Aluminum was applied by threading a 5 mm steel wire. 500% by heating aluminum-coated steel wire with electricity
While heating to tl', the rolling speed is set to 5 by rolling rolls
It was rolled at 77 g/min. While continuing this heating, the steel wire was drawn using a wire drawing die 17 to a diameter of 2.5 fl to obtain a high quality aluminum-coated composite steel wire.

めて容易である。As mentioned above, according to the method for manufacturing composite wire of the present invention, the risk of explosion is almost the same as the aluminum powder is not handled in the atmosphere, and the suspension is handled in the atmosphere. Therefore, equipment for non-oxidation prevention is costly. Also,
By adopting powder granularity for certain aluminum,
It is possible to apply aluminum to the surface of the wire with a uniform thickness,
As a result, a composite wire with less uneven thickness can be obtained. In particular, with conventional methods, it is difficult to manufacture composite wires with thin coatings due to uneven thickness, etc., and it is extremely difficult to manufacture composite wires with extremely thin coatings, but the method of the present invention makes it extremely easy to manufacture. It is.

Also, aluminum alloy powder can be used to form aluminum powder.
