術が提案され、かつ一部実用に供されている。 Direct heat treatment of the wire rod that comes out of the final hot wire rod rolling mill involves blowing a coolant such as air onto the hot rolled wire rod that has been formed into a spiral coil shape in a loop forming machine while being transported by a conveyor. It is carried out with
Regarding this direct heat treatment method, several techniques have already been proposed, and some of them have been put into practical use.

されていない。 However, in method (i) above, each loop is
Difficult to hold each item vertically,
Since the loop holding mechanism applies an external support force toward the center of the loop at the horizontal diameter position of the loop, the loop is easily deformed (the perfect circle is lost), and the appearance of the package after concentration is poor. During conditioning cooling, the loop itself undergoes creep deformation due to its own weight, which has disadvantages such as worsening the appearance of the load after concentrating, so it is currently hardly put into practical use. Method (i) includes a method of regulating and cooling the loop while restraining it with a support rod or claw in order to prevent the loop from falling due to its own weight, a method of dropping the coil into boiling water and regulating and cooling it with the boiling water, etc. There are various methods, but all of them have the disadvantage that uniform heat treatment cannot be guaranteed because the work is complicated, loops overlap each other, and the cooling effect of the refrigerant is unstable. Method (iii) causes a difference in the cooling rate between the overlapping part of the non-concentric loops and the other parts, making it impossible to perform uniform heat treatment in the circumferential direction of the loop. For mmφ wire rods, the variation in tensile strength per loop in lead patenting is within about 2 kg/mm, whereas in the case of direct patenting using the same method, a large variation of around 8 kg/mm2 occurs. Note that method (iv) requires extremely large-scale equipment and is therefore hardly ever put into practical use.

れてきたが、根本的には、鉛パテンテイング処理
材なみの効果が得られていないのが実情である。 In the case of the Stelmor method, as mentioned above, the spiral coils from the loop forming machine are conveyed in a non-concentric manner on a chain conveyor or roller conveyor above the bed, and during the conveyance process, the spiral coils are conveyed from the bottom of the bed. This is a very simple method that performs patenting treatment by adjusting cooling using blast air and has excellent operational stability. However, in this case, because the loops overlap, cooling spots occur, and as a result, the strength decreases. Variations occur, and a product comparable to lead patented material cannot be obtained. In order to solve this problem, measures such as applying a stronger blast only to the overlapped portions, and shifting the overlapped portions of the loops using a baffle roller, etc. during conveyance on a chain conveyor or roller conveyor above the bed have been taken. However, the fundamental reality is that they have not been as effective as lead patented materials.

でキヤツチングするのは困難である。 Therefore, as shown in FIG. 1, a method has been attempted in which the spiral coil loops are conveyed without overlapping to perform controlled cooling. Next, to explain the outline of the direct patenting method, Figure 1 (the figure is a side view,
As shown in XX sectional view, and is a plan view, the hot rolled wire rod (i) supplied from the final hot wire rod rolling machine is passed through the loop forming machine 2 which rotates around the horizontal axis. The spiral coil 3 is formed at the side conveyor 4, and the pitch P between each loop and the inclination angle α with respect to the horizontal axis H are maintained within a certain range by the claws 5 etc. provided on the side conveyor 4.
and is transferred to the right in the figure. During this transfer, the helical coil 3 is regulated and cooled by a fluid coolant 7, such as air, which is fed from the bottom to the top of the bed conveyor 6, after which it is introduced into a suitable concentrator. The controlled cooling effect during such transfer depends on the pitch between each loop of the helical coil 3 and the refrigerant delivery angle with respect to the helical coil 3. In this case, effective controlled cooling can be obtained and the strength variation can be suppressed to the same level as that of lead patenting material.
It is difficult to catch.

いためである。 In other words, as shown in FIG. 2, it is impossible to bring the loop outlet 8 formed by the guide pipe of the loop forming machine 2 and the claw 5 of the side conveyor 4 close to each other dimensionally, so that the loop falls freely (moves). ), the claw 5 can only catch the spiral coil 3, and the claw 5 and the loop may interfere with each other, or a catching error or multiple loops may be caught. This may be caused by variations in the rotational speed of the loop forming machine 2 or by the loop being pulled by the previous loop to be caught by the helical coil 3.
This is because the loops are not aligned at the proper catching position 9.
この問題の解決策としては、ループ吐出口８近

し、寸法的にも限度であるので、僅かでも接近さ
せるためには、
(1) 爪５のピツチをできだけ長くとる。 As a solution to this problem, the claw 5 should be moved as close as possible to the loop discharge port 8. However, there is a limit due to dimensions, so in order to make them even slightly closer, (1) Make the pitch of the claws 5 as long as possible.
(2) チエーンスプロケツト１０の歯数をできるだ
け減らす。(2) Reduce the number of teeth on chain sprocket 10 as much as possible.
(3) 爪５の長さをできだけ短かくする。(3) Make the length of claw 5 as short as possible.
こと等が考えられるが、これ等の場合には、次の

も無理がある。(3)の場合、爪５を短かくすると、
搬送途中の調整冷却による変態動作時のクリープ
変形により、ループが爪５から外れる恐れがあ
る。However, in these cases, the following problems arise. That is, in case (1), the conveyor speed is already too fast and the design is impossible, but it becomes even faster and becomes even more difficult. In the case of (2), reducing the diameter of the chain sprocket 10 is unreasonable in terms of service life since it rotates at high speed. In the case of (3), if the claw 5 is shortened,
There is a risk that the loop may come off from the claw 5 due to creep deformation during the transformation operation due to adjustment cooling during transportation.
従つて、圧延線速100m／secという今後の技術
に対応するためには、第１図に示すような方式は
不可能である。 Therefore, in order to cope with the future technology of rolling line speed of 100 m/sec, the method shown in FIG. 1 is not possible.

The feature is that the hot-rolled wire is formed into a spiral coil using a loop forming machine, and the spiral coil is conveyed while being forcedly cooled. In the heat treatment equipment, a frame into which the spiral coil is fitted is provided in the conveying direction on the exit side of the loop forming machine, and a chain conveyor is provided on the top of this frame to hold and convey the spiral coil in a vertical position from the inside. The present invention is characterized in that a chain conveyor is provided below the frame and is equipped with a large number of rollers that can run on rails and support the frame in a floating state.

次重ね倒し、集束機に搬送して結束する。 In the above configuration, the wire rod 11 finished in the finishing mill is supplied to the guide pipe 16 in the loop forming machine 14 via the water cooler 12 and the pinch roller 13, and the loop forming machine 14 is rotated according to the wire speed. By rotating it several times, a helical coil 15 of a predetermined warp is formed. Then, a helical coil 15 formed by the loop forming machine 14
are received by the upper chain conveyor 19 located in the loop and operated to maintain a predetermined pitch, and are held in a vertical position by the upper chain conveyor 19 and conveyed in the direction indicated by the arrow a. When the spiral coil 15 reaches the blast passage 38 constituted by the inner and outer peripheral ducts 39 and 40, the blast passage 38
