A winding machine that forms hot-rolled wire into a coil; a device that unrolls hot-rolled wire into a non-concentric ring, then performs so-called direct heat treatment by air cooling, etc., and then converges it into a coil. There are devices for transporting wire rod coils while cooling them to a predetermined position, and coil finishing equipment such as a binding machine for performing the necessary finishing. Some or all of these equipment are combined to create a factory. arranged in a series within.
これら一連の設備で、いわゆる直接熱処理装置

The wire is formed into non-concentric rings in the head (loop layer), and as it travels on the moving conveyor, controlled cooling with hot water, forced air cooling or natural cooling is performed to obtain the desired metallurgical structure or surface scale properties. There is an air cooling device.
この直接熱処理装置では、熱間圧延された線材
を非同心円状に展開させることが重要なポイント
であり、これを達成する設備としてレーイングヘ
ツドを有しているのである。 An important point in this direct heat treatment apparatus is to develop the hot-rolled wire in a non-concentric manner, and a laying head is provided as equipment for achieving this.
