保護が図られている。In the conventional heat treatment of metal wires, (a) the wires are coiled, stacked on racks or trays, and heated in a pot-type or conveyor-type heat treatment furnace. Furthermore, only in cases where uniformity of the wire properties is strictly required, (b) the coiled wire is fed into a tunnel furnace while unraveling, and heating is performed in a single wire state. If it is necessary to prevent surface contamination or oxidation of the wire during heat treatment, various gases are introduced depending on the purpose to protect the surface.
ところで、上記（イ）の熱処理法では処理能力を有する
ものの（イ）、（ロ）の方法それぞれ実用上の短所があ
る。（イ）の方法の問題点は次のとおりである。By the way, although the above heat treatment method (a) has processing capacity, each of the methods (a) and (b) has practical disadvantages. The problems with method (b) are as follows.
■コイル内外部、上下部において加熱むらを生じ易い。■Heating tends to occur unevenly inside and outside the coil, at the top and bottom.
■コイルの底部においては自重により損傷をこうむる恐

Ancillary items such as conveyors are also heated at the same time, resulting in large heat loss and, due to the structure, a large amount of protective gas is consumed.

出される。That is, the present invention provides a conical or cylindrical drum having a desired number of grooves or fins on the circumference, which is an annular disk.
More than one drum is housed in a heat treatment furnace, and each drum is connected through a shaft from outside the furnace and rotated in synchronization. The heat treatment furnace (hereinafter referred to as the furnace) is constructed so that the heat treatment wire introduced from outside is wound around each drum in sequence from the groove at the end of the drum, and after filling the last groove, it is pulled out of the furnace. . When each drum is rotated after the temperature inside the furnace is raised to a desired temperature, the wire for treatment is taken into the furnace and the annealed wire is discharged in response to the rotation speed.
ドラムを円錐状に設計する理由は、これにより線材取入
れ端のドラムの周長と取り出し端のドラムの周長を変え

わゆる、伸線の目的の為である。The reason why the drum is designed in a conical shape is that by changing the circumference of the drum at the wire intake end and the drum at the withdrawal end, it is possible to intentionally stretch the wire during annealing, which is the purpose of wire drawing. It is for this purpose.
