A novel method that can perform slow cooling or rapid cooling at any cooling rate is described, for example, in Japanese Patent Application No. 54-116678 (Japanese Unexamined Patent Publication No. 56-41324) entitled "Hot-rolled wire rod cooling method and cooling device". A separate application has been filed.
この冷却方式の概要を第1図に基づいて説明する。An outline of this cooling method will be explained based on FIG. 1.

中心近傍からの抜熱(放熱促進)を図っている。7 is a wire convergence device. The wire ring 3 on the stepped conveyor 4 inside the heat insulating cover 5 is transferred in the form of non-concentric, mutually overlapping 9-layer thick coils, and is once stripped off at the stepped portion 8 of the stepped conveyor 40 to form coils on both sides with high coil density. The aim is to remove heat (promote heat radiation) from near the center of the part.

The thick coiled wire rings 3 that have reached the step position fall from the upper conveyor 4a onto the lower conveyor 4b, and at this time, the rings are unraveled one by one and are sprayed with refrigerant (not shown). It is cooled by a refrigerant (air, inert gas, mist, water, etc. whose temperature is higher than the atmospheric temperature or lower than the atmospheric temperature inside the heat insulating cover 5) from the nozzle.
この線材リング3の落下時にはリングの最先端が3aに
示すように下方側コンベア4bのコーラ間に突込み、リ
ングの移送に支障を来たす訃それがある。When the wire ring 3 falls, the leading edge of the ring may fall between the collages on the lower conveyor 4b as shown in 3a, which may impede the transfer of the ring.
線材は所定の速度で移送しながら冷却されることが必要
であるので、このような突込み現象はラインの中断を招
き、生産性を低下させるため好1しくない。Since the wire needs to be cooled while being transported at a predetermined speed, such a plunging phenomenon is undesirable because it causes interruption of the line and reduces productivity.
また、この突込み現象が要因の一つとなって線材リング
(線材コイル)3の形状が不良になり、品質を左右する
ので好ましくない。Further, this thrusting phenomenon is one of the factors that causes the shape of the wire ring (wire coil) 3 to become defective, which is undesirable because it affects the quality.
さらにこの突込み現象による線材リング(線材コイル)
3の形状不良が発生すると、線材リング(線材コイル)

。Furthermore, wire rings (wire coils) due to this plunging phenomenon
If the defective shape of 3 occurs, the wire ring (wire coil)
It becomes difficult to make the temperature of No. 3 uniform throughout.
従って、線材リング3が段差コンベア40段差個所8に
おいて、下方側コンベア4bの落下位置に対して、該リ
ング3の最先端と最終端は、略同様落下速度でほぐされ
つつ落下させれば、上記難点を解決することができる。Therefore, if the wire ring 3 is dropped at the step portion 8 of the step conveyor 40 with respect to the falling position of the lower conveyor 4b, the leading edge and the final end of the ring 3 are loosened and dropped at substantially the same falling speed. Difficulties can be resolved.

線材の品質目標に応じて適宜選択できる効果がある。Furthermore, if the level difference conveyor 4 can be raised and lowered freely as in the case of a tilting cheeple system, the level difference (the upper side conveyor 4
The transfer part a is 2
00 to 400 mm) can be appropriately selected depending on the quality target of the wire to be cooled.
しかし、本考案において段差コンベア4は昇降自在か、
固定式であるかは特に制限されず、選択は当業者の意志
による。However, in this invention, is it possible to raise and lower the step conveyor 4?
There is no particular restriction on whether it is a fixed type, and the selection is at the discretion of those skilled in the art.
以下本考案の具体例を図面に基づいて説明する。A specific example of the present invention will be described below based on the drawings.
第3図は、第1図の段差コンベア40本考案に係る段差
個所を示す斜視説明図、第4図は第3図の平面図である
。FIG. 3 is a perspective explanatory view showing the step portion of the step conveyor 40 of FIG. 1 according to the present invention, and FIG. 4 is a plan view of FIG. 3.
図示の如く、段差コンベア4の段差個所8を構成する上
方側コンベア4aの乗り継ぎ最先端ローラ9のみを片持
ち駆動方式としてローラ9とローラ9とを分割し、対向
するローラ面を略円錐状に形成している。As shown in the figure, only the topmost transfer roller 9 of the upper conveyor 4a constituting the step portion 8 of the step conveyor 4 is driven in a cantilever manner, and the rollers 9 and 9 are divided, and the opposing roller surfaces are shaped approximately conically. is forming.
この対向する円錐状の組合せ面が、同図に訃いて二点鎖
線で示す線材リング30曲率に応じた切欠案内部10と
なっている。These opposing conical combination surfaces form a notch guide portion 10 corresponding to the curvature of the wire ring 30 shown by the two-dot chain line in the figure.
従って、第4図に平面で示す如く、線材リング3の最終
端Xが通過しつつ上記切欠案内部10より落下し、段差

ング群よりほぐされていく。Therefore, as shown in plan view in FIG. 4, the final end X of the wire ring 3 falls from the notch guide part 10 while passing through, and is unraveled from the following group of wire rings to the lower conveyor 4b forming the stepped portion 8. To go.
この落下の態様は上方側コンベア4aの乗り継ぎ部分が
略平坦なローラ配置となっているので、線材リング3の
最先端Yと最後端Xとは略同−落下速度で下方側コンベ
ア4bの落下位置へ落下する。Since the transition part of the upper conveyor 4a has a substantially flat roller arrangement, the leading edge Y and the rearmost edge X of the wire ring 3 fall at approximately the same falling speed and fall position on the lower conveyor 4b. fall to.

落下するものである。In other words, when the wire ring 3 falls like this, when the leading edge Y of the wire ring 3 protrudes forward from the stepped portion 8 and the rearmost end X reaches the notch guide portion 10 as shown in FIG. Since X cannot be supported (becomes free) by the opposing substantially conical portions of rollers 9 and 9, the leading edge Y
and the rearmost end X fall to the lower conveyor 4b at approximately the same falling speed.
従って、第2図に拡大側するようなコイルはぐしされつ
つ落下する線材リング3の突掛は現象は、はとんど発生
する機会がない。Therefore, there is almost no chance that the phenomenon of the wire ring 3 falling while being uncoiled as shown in the enlarged view in FIG. 2 will occur.
このため、段差個所8を落下する線材リング3の形状は
、最も好ましい形状を維持し、品質を害しないばか9か
、線材リング全体に亘って温度をほぼ均一化することが
できるので、バラツキの極めて小さい金属組織及び機械
的性質を得ることができる。Therefore, the shape of the wire ring 3 falling through the stepped portion 8 can be maintained in the most preferable shape without impairing quality, and the temperature can be made almost uniform over the entire wire ring, so that variations can be avoided. Extremely small metallographic structure and mechanical properties can be obtained.
この場合、本考案の上方側コンベア4aと下方側コンベ
ア4bとの段差個所8は、例えば200〜400mmあ

度を最先端と最後端を略同速度とすることができる。In this way, the present invention provides a cantilever drive type roller with a substantially conical portion that corresponds to the curvature of the wire ring at the top of the transfer tip of the upper conveyor of the step conveyor, and is provided with a cantilever drive type roller to match the curvature of the wire ring. Since the notch guide portion is configured accordingly, the wire ring passing through this stepped portion can fall at approximately the same speed at the leading end and the trailing end.
従ってその段差位置(はぐし位置)にてコイルの先端が
下方側コンベアのローラ間に突込むことなく円滑にコン
ベア上へ順次乗り継ぎ安定して搬送されることになる。Therefore, at the step position (peeling position), the tip of the coil does not stick between the rollers of the lower conveyor, and is smoothly transferred onto the conveyor and stably conveyed.
