【考案の詳細な説明】
本考案は金属帯の冷却装置に関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cooling device for metal strips.
金属帯を、ロールの胴長方向に中空孔を設けて
冷媒を流通させる冷却ロールによつて冷却する手
段が知られているが、この手段においては下記の
３点を満足させる必要がある。 A method is known in which a metal strip is cooled by a cooling roll having hollow holes in the longitudinal direction of the roll to allow a coolant to flow therethrough, but this method requires the following three points to be satisfied.
(1) 冷却される金属帯が長手方向及び幅方向のい
ずれにも一様に冷却され、金属帯の材質むらや
金属帯の不均一な伸縮が生じないこと。(1) The metal strip to be cooled is cooled uniformly in both the longitudinal and width directions, and there is no unevenness in the material of the metal strip or uneven expansion or contraction of the metal strip.
(2) ロールが周方向（即ち金属帯の長手方向）及
びロールが軸方向（金属帯の幅方向）のいずれ
の方向にも均一な温度となり、均一に伸縮する
こと。(2) The temperature of the roll should be uniform both in the circumferential direction (i.e., the longitudinal direction of the metal strip) and in the axial direction (the width direction of the metal strip), and the roll should expand and contract uniformly.
(3) ロールが冷媒の供給と排出及び駆動に関して
簡単な構造であること。(3) The roll has a simple structure in terms of refrigerant supply and discharge and drive.
前記のうち、金属帯とロールの伸縮を均一にす
ることは金属帯の横流れ又は蛇行を防止するため
に必要な条件である。 Among the above, uniform expansion and contraction of the metal band and roll is a necessary condition to prevent the metal band from flowing sideways or meandering.
しかるに、既に提案されている特開昭51−
104417、特開昭58−61229、特開昭58−61230及び
特開昭58−61237の考案は、いずれもロール胴部
にスパイラル状の流路を形成したものであり、冷
媒をロールの一端から供給し、他端から排出させ
るようになつている。 However, the already proposed JP-A-51-
104417, JP-A-58-61229, JP-A-58-61230, and JP-A-58-61237 all have a spiral flow path formed in the roll body, allowing the refrigerant to flow from one end of the roll. It is designed to be supplied and discharged from the other end.
前記の構成は、前記の必要条件に照らしてみる
と極めて不都合であることがわかる。即ち、冷媒
は、ロールの一端から他端に流れることになり、
ロールの胴部の温度分布が、冷媒供給側から冷媒
排出側に向つて高温となる。これによつて金属帯
の温度分布も不均一になり、冷却後の金属帯の材
質が不均一になる。更に、ロールの胴部の直径及
び金属帯の伸縮が不均一になることから走行中に
金属帯の横流又は蛇行が発生する。 The above arrangement proves to be extremely disadvantageous in the light of the above requirements. That is, the refrigerant will flow from one end of the roll to the other end,
The temperature distribution in the body of the roll increases from the refrigerant supply side to the refrigerant discharge side. As a result, the temperature distribution of the metal band becomes non-uniform, and the material of the metal band after cooling becomes non-uniform. Furthermore, since the diameter of the body of the roll and the expansion and contraction of the metal strip are non-uniform, cross currents or meandering of the metal strip occurs during running.
前記の材質の不均一性と横流れは、連続焼鈍炉
や連続メツキライン等における冷却装置としては
致命的な欠陥である。 The non-uniformity of the material and the lateral flow described above are fatal defects for cooling devices in continuous annealing furnaces, continuous plating lines, etc.
又、冷媒をロールの一端から供給して他端から
排出させることは、ロールの両端にロータリ−ジ
ヨイント等の回転可能な配管継手を接続する必要
が生じることになり、ロールを駆動するための駆
動軸を接続することができず、強いて駆動しよう
とすると、極めて複雑な構造にならざるを得ない
ことになる。 In addition, supplying refrigerant from one end of the roll and discharging it from the other end requires connecting rotatable piping joints such as rotary joints to both ends of the roll, which requires a drive to drive the roll. If the shafts cannot be connected and you are forced to drive it, you will end up with an extremely complicated structure.
そこで、本考案においては金属帯を均一に冷却
することができる金属帯の冷却装置を提供するの
が目的である。 Therefore, an object of the present invention is to provide a cooling device for a metal strip that can uniformly cool the metal strip.
本考案の構成を図面に示す実施例に基き詳細に
説明すると、ロール１の胴部２内面の表面近傍に
複数の往路３ａ，……と復路３ｂ，……を軸方向

出口６に連通する。そして、冷媒供給口５を開口
した軸４ｂの外周にロータリ−ジヨイント等で形
成した回転継手７を接続し、この回転継手７に冷
媒供給管８と冷媒排出管９を設ける。尚、図中１
０，１１は軸受である。 The structure of the present invention will be explained in detail based on the embodiment shown in the drawings.A plurality of outward paths 3a, . . . and return paths 3b, . Then, on one shaft 4a side of the roll 2, adjacent forward and return paths 3a and 3b are connected to a communication path 3.
Connect with c. Also, on the other shaft 4b, the outgoing path 3
a,... are communicated with the refrigerant supply port 5, and return paths 3b,...
... are communicated with a refrigerant discharge port 6 located closer to the shaft end than the refrigerant supply port 5. A rotary joint 7 formed by a rotary joint or the like is connected to the outer periphery of the shaft 4b with the refrigerant supply port 5 open, and a refrigerant supply pipe 8 and a refrigerant discharge pipe 9 are provided to the rotary joint 7. In addition, 1 in the figure
0 and 11 are bearings.
前記ロール１において、駆動する際には連通路
４ａ側を駆動軸に接続する。 When the roll 1 is driven, the communication path 4a side is connected to the drive shaft.
本実施例は前記のように構成したもので、冷媒
供給管８から供給した冷媒は回転継手７から往路
３ａを通り、連通路３ｃで折返し、復路３ｂから
回転継手７を介して冷媒排出管９を通して排出さ
せるようになつている。 The present embodiment is configured as described above, in which the refrigerant supplied from the refrigerant supply pipe 8 passes through the outgoing path 3a from the rotary joint 7, turns back at the communication path 3c, and passes through the refrigerant discharge pipe 9 from the incoming path 3b via the rotary joint 7. It is designed to be discharged through.
前記の冷媒の流れによる温度θは、冷媒供給口
５においてはθSであつたものが、往路３ａにおい
て、金属帯を冷却することにより、金属帯幅端部
からの距離に比例して上昇し、連通路３ｃまで流
れる間にθAまで上昇する。更に冷媒は復路３ｂに
おいて金属帯を冷却することにより冷媒排出口６
まで流れる間にθEまで上昇する。 The temperature θ due to the flow of the refrigerant, which was θ S at the refrigerant supply port 5, increases in proportion to the distance from the width end of the metal band by cooling the metal band in the outward path 3a. , it rises to θ A while flowing to the communication path 3c. Furthermore, the refrigerant cools the metal band on the return path 3b, and then flows to the refrigerant outlet 6.
It rises to θ E while flowing to .
ここで、θA≒θS＋θE／２であり、更に、胴表層部
における熱伝導により胴表面においては、往路３
ａに対応する部分と、復路３ｂに対応する部分の
温度は、夫々往路３ａの温度θSと、復路３ｂの温
度θEとの平均値即ち、
θS＋θE／２≒θAとなり、連通路３ｃの温度θAと等し
くなる。 Here, θ A ≒ θ S + θ E /2, and furthermore, due to the heat conduction in the shell surface layer, the forward path 3
The temperatures of the part corresponding to a and the part corresponding to the return trip 3b are the average value of the temperature θ S of the outward trip 3a and the temperature θ E of the return trip 3b, that is, θ S +θ E /2≈θ A , and are continuous. The temperature becomes equal to the temperature θ A of the passage 3c.
即ち、ロール１の胴部２の表面温度はロール１
の軸方向に均一となり、ロール胴の径方向及び金
属帯の温度も均一となることから、金属帯の材質
は金属帯の幅方向に均一となり、又金属帯の横流
れもなくなる。 That is, the surface temperature of the body 2 of the roll 1 is
Since the temperature of the metal strip becomes uniform in the axial direction of the roll cylinder and the temperature of the metal strip in the radial direction of the roll cylinder and the temperature of the metal strip are also uniform, the material of the metal strip becomes uniform in the width direction of the metal strip, and there is no lateral flow of the metal strip.
尚、胴部の軸方向の長さより、金属帯の幅が小
さい時、金属帯に接している胴部は金属帯に接し
ていない部分より高温となり、胴部の表面部と内
側との間に隙間が生じると、冷媒がバイパスし、
冷却能が低下することになるので、このようなこ
とがないよう胴部に冷媒を流す往復路を鋳ぐるん
で形成する必要がある。 Note that when the width of the metal band is smaller than the length of the body in the axial direction, the body that is in contact with the metal band will be hotter than the part that is not in contact with the metal band, and there will be a gap between the surface and the inside of the body. When a gap occurs, the refrigerant bypasses
Since this will reduce the cooling capacity, it is necessary to form a reciprocating path through which the refrigerant flows through the body to prevent this from happening.
尚、前記実施例においては冷媒の通路をロール
の軸に平行となるよう設けたが、冷媒の通路はロ
ールの軸心に対し傾けたいわゆるスキユー構造と
してもよいものである。 In the above embodiment, the refrigerant passage was provided parallel to the axis of the roll, but the refrigerant passage may have a so-called skew structure in which it is inclined with respect to the axis of the roll.
本考案は前記のような構成、作用を有するもの

出及び駆動構造を簡単にすることができる。 The present invention has the above-mentioned structure and function, and since the refrigerant supply and discharge are provided on the same side and the refrigerant is reciprocated, the metal strip is uniformly cooled in the longitudinal and width directions. The temperature is uniform in the circumferential and axial directions of the roll, and the expansion and contraction of the metal band and roll are uniform, which prevents lateral flow and meandering of the metal band, and simplifies the supply and discharge of refrigerant and the drive structure. be able to.
