2. Description of the Related Art A dipping method is known as a processing method for forming an anticorrosion coating on a wire used for manufacturing bolts, nuts and other forged machine parts. In this dipping method, as shown in FIG. 3, a coil 10 of a wire for processing is hung on a hacker 11 having a U-shape, and the hacker 11 is hung by a hoist (not shown),

Then, it is dried in a dryer 17 (however, if the lubricant is at a high temperature of 80 ° C. or higher, drying is omitted), the coil 10 is rewound by the uncoiler 18, and the wire rod 10a is pulled out by the first pulling roller 19a. After passing through the die of the skin pass 20 and being drawn out by the second pulling roller 19b to make the wire diameter uniform, the wire was wound around the winding core 21 and the coil 10A was formed again.

Since the above-mentioned dipping method is a wet treatment, it requires a large amount of industrial water and wastewater treatment and is liable to cause pollution, and harmful gas is generated due to washing with hot water and heating of the chemical conversion coating solution, resulting in atmospheric pollution. In addition, a total of 10 dipping tanks and a wide space for a dryer are required, and the time loss due to drying also increases the processing time, and the concentration control in the pickling tank, water washing tank and phosphate tank is possible. Difficult,
The work was troublesome because the chemical conversion solution in the chemical conversion coating tank had to be replaced with a phosphate solution or other chemicals depending on the type of wire.

However, in this strand method, since the pickling step and the water washing step of the dipping method are replaced by a shot blasting machine, the amount of industrial water used is reduced and space can be saved. Since it does not completely abolish, but the conversion coating is formed by a wet process, wastewater treatment is still required, and the problem of air pollution remains similar to the dipping method, and since a harder shot or grit is used, shot scratches and grit There is a problem that adhesion occurs. Although the above is for a long metal material such as a wire rod, there is a similar problem in a metal material of any form such as a billet or a slab.

Wires made of metals such as copper and aluminum, long materials such as strips, slabs, billets and other shaped articles of any shape are available. Then, in order to uniformly treat the surface of the metal material, the metal material can be moved by an appropriate means depending on its form. For example, when processing long metal materials such as wire rods and strips, many guides are placed in the chamber, and the guides guide the long metal materials to form arbitrary curves such as loops, corrugations, and meanders. The target surface treatment can be completed while the long metal material stays in the narrow chamber by spraying the mixture from a plurality of nozzles that surround the metal material.
