本考案は走行中の熱鋼板を均一に冷却するため
のラミナー冷却用ノズルに係る。[Detailed Description of the Invention] The present invention relates to a laminar cooling nozzle for uniformly cooling a running hot steel plate.
通常熱鋼板を均一に急冷する装置としてスリツ
トノズルを用い、ラミナーフロウ（層流）により
効率的に冷却するものが知られている。 It is known that a slit nozzle is used to uniformly rapidly cool a hot steel plate, and a laminar flow is used to efficiently cool the heated steel plate.
即ちこの冷却装置は剛性の大きな管に一般的に
はパツキンを介して一定の隙間をもつスリツトノ
ズルが接続されたものである。 That is, this cooling device generally has a slit nozzle with a certain gap connected to a highly rigid tube through a packing.
而してこれらのノズルは、従来安定したラミナ
ーフローを維持するという観点からスリツトの間
隙は強固に固定されるのが通例である。 In these nozzles, the gap between the slits is usually firmly fixed from the viewpoint of maintaining a stable laminar flow.

却が著しく阻害されてきた。 However, when such a tube is used, even if a heat shield plate is interposed by a hot steel plate that passes under the cooling device, the slits are subject to thermal distortion, and the predetermined slit nozzle changes greatly, causing the plate width direction to change. uniform cooling has been significantly hindered.
第１図にスリツトノズル間隙変化をグラフで示

本考案はノズル部を移動可能な装置に取り付
け、スリツトノズル間隙を可変にすることにより
前記の問題が解決するものである。 The present invention solves the above problem by attaching the nozzle part to a movable device and making the gap between the slit nozzles variable.
以下本考案を図面によつて詳述する。 The present invention will be explained in detail below with reference to the drawings.
第２図は本考案の断面説明図、第３図は本考案
の正面説明図である。 FIG. 2 is a cross-sectional explanatory view of the present invention, and FIG. 3 is a front explanatory view of the present invention.

動する。６はアームである。 In the figure, a slit with a desired gap is provided along the entire length of a tube 1, and a slit nozzle 3 is attached via a packing 2. The slit nozzle 3 is connected to a slit nozzle gap switch 5 by a support rod 7. Further, the slit nozzle switch is operated in conjunction with the position detector 4 in response to a signal from the position detector 4. 6 is an arm.
即ち本考案によるときはスリツトノズル間隙を

フイードバツクさせながら所定のスリツトノズル
間隙まで移動させる。 That is, according to the present invention, since the slit nozzle gap is configured to be variable, a predetermined slit nozzle gap is memorized as a set value, and when the position detector 4 detects a change in the slit nozzle gap, the slit nozzle gap opening/closing device 5 is activated, and the position detector The slit nozzle is moved to a predetermined gap while feeding back the signal No. 4.
また目づまりが発生した場合には、許容される

なる異物を落下させる。 In addition, when clogging occurs, the foreign matter that causes the clogging is dropped by moving it to the maximum allowable gap.
本考案は以上の通り構成されるが、そのほかノ
ズルを支持する管１自体を合成樹脂など剛性の小

変にすることもでき、本考案はこれらの手段をも
含むものである。 The present invention is constructed as described above, but the slit can also be artificially made variable by making the tube 1 itself that supports the nozzle made of a material with low rigidity such as synthetic resin. It also includes.

却、ｂは補正冷却を示している。 With such a device, the slit nozzle gap can be changed in the width direction of the plate, making it possible to create an arbitrary cooling pattern. For example, the drive side is generally hotter than the operation side, and to compensate for this condition, it is possible to increase the gap between the slit nozzles on the drive side and create a water flow distribution as shown in Figure 4. It is possible. In the figure, a shows uniform cooling, and b shows corrected cooling.
本考案は上述のようにスリツトノズル間隙保持

決し得て、実用的価値は大である。 As described above, the present invention improves the accuracy of maintaining the gap between the slit nozzles, makes it possible to compensate for thermal deformation, etc., and solves clogging caused by sludge mixed in the refrigerant, and has great practical value.
