【発明の詳細な説明】 〔産業上の利用分野〕 本発明は帯鋼を噴流酸洗液によって連続して酸洗する噴
流酸洗装置に関する。The present invention relates to a jet pickling apparatus for continuously pickling a steel strip with a jet pickling solution.
第３図は従来の噴流酸洗槽の破断側面図、第４図は第３
図のIV−IV断面図である。FIG. 3 is a cutaway side view of a conventional jet pickling tank, and FIG.
FIG. 4 is a sectional view taken along the line IV-IV in the figure.
上図に示すように、缶体１の底面と、カバー２と側壁６
の入側スキッド３及び出側スキッド４とによって囲まれ

から排液路15、集液室16、排液管17を経て循環槽（図示
せず）に戻して循環させる。As shown in the above figure, the bottom of the can body 1, the cover 2 and the side wall 6
In the treatment tank 10 surrounded by the inlet side skid 3 and the outlet side skid 4, a pickling tank R of a circulation tank (not shown) is provided with an upper nozzle header 12 on the inlet side, an upper nozzle header 13 on the outlet side, and Drainage port 7 ejected from the lower nozzle header 14 and formed in the side wall 6
Then, the liquid is returned to a circulation tank (not shown) through the drainage path 15, the liquid collection chamber 16, and the drainage pipe 17 for circulation.
そして、この処理槽10に帯鋼Ｓを入側スキッド３、出側
スキッド４、中間スキッド５によって支持しながら走行
させ、その両面を酸洗処理する。Then, the strip steel S is run while being supported by the inlet side skid 3, the outlet side skid 4, and the intermediate skid 5 in this treatment tank 10, and both surfaces thereof are pickled.
上記従来の装置では、次のような問題点があった。 The above conventional device has the following problems.
（ａ） 入側には上ノズルヘッダ12は１組しかなく、帯
鋼Ｓの上方の空中に配設されているので、例えば300〜5
00m/分のような高速のラインでは、酸洗液Ｒが供給不足
になる。このため、処理槽10に酸洗液Ｒを充満させるこ
とが困難となる。酸洗液Ｒが充満されないと帯鋼Ｓが液
面に浮上し、酸洗不良になる。(A) Since there is only one set of the upper nozzle header 12 on the entrance side and it is arranged in the air above the strip steel S, for example, 300 to 5
In a high-speed line such as 00 m / min, the pickling solution R is insufficiently supplied. For this reason, it becomes difficult to fill the processing bath 10 with the pickling solution R. If the pickling solution R is not filled, the strip steel S floats on the surface of the liquid, resulting in poor pickling.
（ｂ） 処理槽10内の帯鋼Ｓの出側の下面は出側スキッ
ド４によって摺動支持され水切りされているので、出側
の帯鋼Ｓの下方の下ノズルヘッダ14がなくても酸洗液Ｒ
が集液室16に大量に流出することはない。このため、こ
の下ノズルヘッダ14は余分な部品となる。(B) Since the lower surface of the strip steel S in the processing tank 10 on the outlet side is slidably supported by the outlet side skid 4 and drained, even if the lower nozzle header 14 below the outlet steel strip S is not provided, the acid is removed. Wash liquid R
Does not flow into the collection chamber 16 in a large amount. Therefore, the lower nozzle header 14 is an extra component.
本発明は上記課題を解決するため次の手段を講ずる。 The present invention takes the following means in order to solve the above problems.
すなわち、噴流酸洗槽として、走行する帯鋼をノズルヘ
ッダから入側及び出側にスキッドを持つ処理槽内に噴出

て、前記ノズルヘッダを前記処理槽の入側のスキッドの
前方でかつ前記帯鋼の上方及び同入側のスキッドの後方
でかつ同帯鋼の下方と、前記処理槽の出側のスキッドの
後方でかつ前記帯鋼の上方とに配設する。That is, as a jet pickling tank, in a jet pickling tank for continuously pickling a running steel strip from a nozzle header into a treatment tank having skids on the inlet side and the outlet side by pickling, the nozzle header The front side of the skid on the inlet side of the treatment tank and above the steel strip and behind the skid on the same inlet side and below the steel strip, and behind the skid on the outlet side of the treatment tank and the steel strip. And above.
上記手段により、酸洗液が入側上方のノズルヘッダと入
側下方のノズルヘッダから、処理槽上流部において帯鋼

される。By the above means, the pickling solution is jetted from the nozzle header above the inlet side and the nozzle header below the inlet side from the top and bottom of the strip steel in the upstream part of the treatment tank to fill the inside of the treatment tank and the nozzle header above the outlet side. Therefore, in the downstream portion, it is jetted from above the strip steel and filled in the processing tank. A sufficient amount of pickling solution is supplied from the nozzle headers for the treatment, and a large amount is supplied on the upstream side, and the steel strip travels backwards, so that the flow becomes smooth, and the acid concentration and temperature in the treatment tank are increased. Maintained uniform.
このようにして帯鋼の高速酸洗処理が行なわれる。In this way, the high-speed pickling treatment of the steel strip is performed.

Is lower than the height of the side wall 7 by a predetermined amount. Further, an outlet skid 4 which also serves as a rear wall is provided at the rear end of the processing tank 10. The height of the outgoing skid 4 is the same as that of the incoming skid 3. A plurality of intermediate skids 5 are provided in parallel with the entrance skid 3 between the entrance skid 3 and the exit skid 4. The height of the intermediate skid 5 is the same as the height of the entrance side skid 3. The rear processing belt S runs backward on the skids 3, 4, 5 along the side wall 6.

られ噴口を前方下方に向けている。An upper (first) inlet-side nozzle header 12 is provided parallel to the skid 3 at the upper front of the inlet-side skid 3, and the nozzle is directed rearward and downward. Further, on the downstream side of the inlet side skid 3 and below the steel strip S, an inlet side lower (second) nozzle header 11 is provided in the liquid parallel to the skid 3, and the jet port is directed rearward and upward. Further, on the upper rear side of the outlet side skid 4, a nozzle header 13 on the upper side of the outlet side (third) is provided in parallel with the skid 4, and the injection port is directed forward and downward.

につながれている。A tank-shaped collecting chamber 16 is provided in front of and behind the inlet skid 3 and the outlet skid 4. A discharge passage 15 is provided outside the side wall, and the front and rear ends thereof are connected to the liquid collection chamber 16. A drainage pipe 17 is provided in the liquid collection chamber 16 and is connected to a circulation tank (not shown).

理槽10から後方へ酸洗液が排出されることを防止する。In the above structure, the pickling solution is jet-supplied from the nozzle headers 11, 12 and 13, fills the treatment tank 10 to treat the strip steel S, and then flows out from the drainage port 7. At this time, the first and second nozzle headers 11 and 12 are on the upstream side, and the second nozzle header is on the rear side of the inlet skid 3, so that a sufficient pickling solution for treatment is supplied to the rear side. In addition, since the steel strip S travels backward, it efficiently flows into the processing tank 10 and the flow becomes smooth. Further, since the third nozzle header 13 ejects the pickling solution from above the steel strip S toward the front behind the delivery side skid 4, it supplies the pickling solution into the treatment tank 10 and moves backward from the treatment tank 10. Prevent discharge of the pickling solution.
また、処理槽10の出側の帯鋼Ｓの下面は出側スキッド４
によって酸洗液Ｒの水切りができて処理槽10外への流出
がほとんどないので、この個所のノズルヘッダが不要に
なる。Further, the lower surface of the strip steel S on the exit side of the processing tank 10 is the exit skid 4
As a result, the pickling solution R can be drained and hardly flows out of the processing tank 10, so that the nozzle header at this location is unnecessary.
以上に説明したように本発明は次の効果を奏する。 As described above, the present invention has the following effects.
（ａ） ノズルヘッダを処理槽の入側の帯鋼の上方及び
下方と、処理槽の出側の帯鋼の上方とに配設したことに

え、出側スキッドの後方かつ上方の噴流により帯鋼が後
方に走行するときに随行する酸洗液の槽外への流出が少
なくなり、槽内を液で充満できるため、帯鋼を良好に酸
洗処理することができる。(A) By arranging the nozzle header above and below the strip steel on the inlet side of the treatment tank and above the strip steel on the outlet side of the treatment tank, the jet stream of the pickling solution is introduced from the inlet side in the tank. In addition to being able to supply enough, the jet stream above and behind the exit skid causes the amount of pickling solution that accompanies the trailing steel strip to run backwards to a lesser extent, which allows the tank to be filled with liquid, so that the steel strip can be filled. Can be satisfactorily pickled.
（ｂ） 処理槽の出側の帯鋼の下面は出側スキッドによ
って酸洗液の水切りができて処理槽外への流出がほとん
どないので、この個所のノズルヘッダを除去し、コスト
の低減を図った。(B) The bottom surface of the strip on the outlet side of the treatment tank can be drained by the skid on the outlet side, and the pickling solution does not flow out of the treatment tank. Therefore, the nozzle header at this point is removed to reduce the cost. planned.
