とを目的とする。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a direct heat treatment apparatus for rolled wire rods.
The spiral coils that come out of the loop forming machine are securely caught one by one so that the loops do not overlap, and are conveyed vertically or at an inclined angle to ensure uniform cooling and control of the spiral coils. The purpose is to reduce strength variations between and within loops and to improve steering stability of equipment.

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 may become deformed (the perfect circle may collapse).
However, it is difficult to put into practical use due to the disadvantages that the loading condition after concentration is poor, and the loop itself undergoes creep deformation due to its own weight during adjustment cooling, making the loading condition even worse after concentration. The current situation is that this has not been done. Method (ii) includes a method in which the loop is restrained with support rods or claws in order to prevent the loop from falling due to its own weight, and a method in which the coil is dropped into boiling water and the coil is cooled in a controlled manner by the boiling water. 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 wire rods, the variation in tensile strength per loop in lead patenting is within about 2 kg/mm 2 , whereas in the case of direct patenting using the same method, a large variation of around 8 kg/mm 2 occurs. Note that method (iv) requires extremely large-scale equipment and is therefore hardly ever put into practical use.

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.

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, as shown in Figure 1 (the figure [ ] is a side view, [ ] is a XX sectional view, and [ ] is a plan view), the final hot wire A hot rolled wire rod 1 supplied from a rolling mill is formed into a spiral coil 3 by a loop forming machine 2 which rotates around a horizontal axis, and is provided on a side conveyor 4 with pawls 5 etc. between each loop. The sheet is placed on the bed conveyor 6 with the pitch P and the inclination angle α relative to the horizontal axis H being maintained within a certain range, and is transported rightward 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.

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 position of the claw 5 of the side conveyor 4 close to each other dimensionally. ), the claws 5 can only catch the spiral coil 3, and even if the claws 5 and the loops interfere, there may be a catching error or a plurality of loops may be caught. This is because the loops of the helical coil 3 are not aligned at the proper catching position 9 due to variations in the rotational speed of the loop forming machine 2 or because the loops are stretched to be caught by the previous loop.
この問題の解決策としては、ループ吐出口８近
くに爪５をできるだけ接近させれば良い。しか
し、寸法的にも限度があるので、僅かでも接近さ
せるためには、
(1) 爪５のピツチをできるだけ長くとる。 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 in terms of 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の長さをできるだけ短かくする。(3) Make the length of claw 5 as short as possible.

小さくするのは、高速回転であるので、寿命的に
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 impossible.

だけリード角を小さくとり、表面硬度も上げた方
が良い。 Note that the loop forming machine 12, screw conveyors 21, 22, and chain conveyors 33, 37 are mechanically synchronized. The side screw conveyor 21 uses screws with unequal pitches to convey the helical coil 13 in an inclined state, but the same effect can be achieved even if the loop forming machine 12 itself is inclined; The screw conveyor 21 is of equal pitch. Further, it is preferable that the screw conveyors 21 and 22 have a lead angle as small as possible and have a high surface hardness so as not to damage the wire rods.
螺旋状コイル１３の搬送姿勢は、傾斜状態に限

ベヤ４３に代えてチエーンコンベヤを使用するこ
ともできる。 The conveying posture of the helical coil 13 is not limited to the inclined state, but may be in the vertical state. Furthermore, a chain conveyor can be used instead of the roller conveyor 43.

優れている。 As described in detail in the embodiments above, in the present invention, the spiral coils output from the loop forming machine are reliably caught one by one on the screw conveyor and then delivered to the chain conveyor. There is no overlap between the loops, and cooling spots can be prevented from occurring during controlled cooling. Therefore,
There is no variation in strength, and strength comparable to lead patenting material can be obtained. It also has excellent operational stability.
