【発明の詳細な説明】
この発明は熱間金属片移送用ロールに関するものである
。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a roll for transferring hot metal pieces.
この種のロールは７００〜１１００℃に熱せられた熱間
金属片が繰返し接し、場合によつては一時的に該熱間金
属片が停止する様な条件下で使用されるので、熱間金属
片が当たつている側とその反射側とでは相当の温度差が
生起し膨張量が異なる結果、ロール全体が大きく曲がつ
て使用不可能となる様な問題がある。This type of roll is used under conditions in which hot metal pieces heated to 700 to 1100°C repeatedly come into contact with each other, and in some cases, the hot metal pieces temporarily stop. There is a considerable temperature difference between the side where the piece is in contact and the side where it is reflected, resulting in a different amount of expansion, which causes the problem that the entire roll is greatly bent and becomes unusable.

は上述の問題を解消するロールを提供しようとするもの
であり、その要旨はロール軸の外周に複数個の分割スリ
ーブを被せたロールであつて、該各分割スリーブは隣接
スリーブとの隣接辺が波状若しくは斜行状を呈しており
かつ相互の隣接スリーブ同土間には若干の間隙が設けら

ールである。In recent years, sleeved rolls in which the outer periphery of the roll shaft is covered with a sleeve made of heat-resistant steel or the like have been used, but even with this sleeved roll, the above-mentioned problems have not yet been solved. The present invention aims to provide a roll that solves the above-mentioned problems.The gist of the invention is to provide a roll in which a plurality of divided sleeves are placed around the outer periphery of a roll shaft, and each divided sleeve is adjacent to an adjacent sleeve. A hot roll having wavy or oblique sides, a slight gap between adjacent sleeves, and only the divided sleeves at both ends being fixed to the roll shaft. This is a roll for transporting metal pieces.
以下図面を参酌し乍ら本願発明を詳述すれば、ロール軸
１の外周に波状（第１図参照）若しくは斜行状（第２図
参照）の分割スリーブ２、２、・・・が被せられており
、その両端部の分割スリーブだけがロール軸１に対して
溶接その他の手段により回転、抜出しない様に固定され
ている。The present invention will be described in detail below with reference to the drawings.The outer periphery of the roll shaft 1 is covered with divided sleeves 2, 2, . Only the divided sleeves at both ends are fixed to the roll shaft 1 by welding or other means so as not to rotate or pull out.
ここで相互の隣接スリーブ同土間に若干の間隙を設ける
というのは常温に於いてある間隙を持たせておき、それ
が熱されてスリーブが一ぱいに膨張した場合に丁度該間
隙が詰まる程度の幅を空けておく為であり、必要以上に
間隙を空けるのは避けるべきである。又この発明の各ス

いうのは、第１図及び第２図に示されるもの以外にも考
えられ、要は中間のスリーブがロール軸１の周りを回転
しない様な形状でかつ出来る限り鋭角状部がない様なも
のであれば差支えがなくその例を第３図に示す。Here, creating a slight gap between adjacent sleeves and the same soil means that there is a certain gap at room temperature, and the width is just enough to fill the gap when the sleeve expands to its fullest when heated. This is to leave a gap between the two, and you should avoid leaving a gap larger than necessary. Also, the shapes of the sides of each sleeve of the present invention, that is, the "wavy" and "oblique" shapes, may be other than those shown in FIGS. There is no problem as long as it has a shape that does not rotate around 1 and has as few acute angles as possible, and an example is shown in FIG.

定されているので熱間金属移送に用いた場合複数個のス
リーブはロール軸の周りを回転することなく熱間金属片
の移送が行なえ、又固定されていない中間のスリーブは
スリーブ間の間隙分のみは自由にロール軸の長手方向に
摺動できるので、万一ロールの片面のみが加熱されロー
ルの両面での膨張量が異なる場合にあつても中間のスリ
ーブが移動することによつて補償されロール全体が曲が
るという欠点が無い。If the roll is to be sprayed with external cooling water, it is desirable that the roll shaft be made of a corrosion-resistant material and that its surface be overlaid with a corrosion-resistant material. In this invention, a plurality of divided sleeves are placed over the outer periphery of the roll shaft with a slight gap between them at room temperature, and the sides of these divided sleeves are wavy or oblique, and the sides of Since the sleeves are fixed to the roll shaft, when used for hot metal transfer, multiple sleeves can transfer hot metal pieces without rotating around the roll shaft, and intermediate sleeves that are not fixed are Since only the gap between the sleeves can freely slide in the longitudinal direction of the roll shaft, even if only one side of the roll is heated and the amount of expansion on both sides of the roll is different, the intermediate sleeve will not move. There is no disadvantage that the entire roll bends, which is compensated for by
又分割スリーブが上述の様に「波状」若しくは「斜行状
」を呈しているのでロールの外周面に形成される間隙も
波状若しくは斜行状となる為に、ロールの使用中にロー
ル軸に対してかかる円周方向の応力の方向と上記間隙の
方向がズレているのでロール軸を切損に至らしめる円周
方向の応力を分散せしめロール寿命を向上させる。Furthermore, since the split sleeve has a wavy or oblique shape as described above, the gap formed on the outer peripheral surface of the roll also has a wavy or oblique shape. Since the direction of the stress in the circumferential direction is misaligned with the direction of the gap, the stress in the circumferential direction that could lead to breakage of the roll shaft is dispersed and the life of the roll is improved.
更には間隙が波状若しくは斜行状である為に、分割スリ
ーブが膨張の為にロールの軸方向に摺動する場合、同じ
摺動量に対しては間隙が直行状の場合に比べ狭い間隙で
よく、それだけ被移送材たる熱間金属片には少ない傷痕
しか残さなくてすみ、しかも間隙が直行状でないので該
傷痕は連続した同一部所に生じる事もないので被移送材
を傷つける度合が少なくてすむという効果がある。Furthermore, since the gap is wavy or oblique, when the split sleeve slides in the axial direction of the roll due to expansion, the gap may be narrower than when the gap is perpendicular for the same amount of sliding. This means that fewer scars need to be left on the hot metal piece that is the material to be transferred, and since the gaps are not perpendicular, the scars will not occur in the same continuous location, so there is less damage to the material to be transferred. There is an effect.
