本考案は連続焼鈍炉の気液ノズルの液抜き装置
に関する。[Detailed Description of the Invention] The present invention relates to a liquid removal device for a gas-liquid nozzle of a continuous annealing furnace.
一般に鋼帯を冷却する方法として、気体と液体
とを噴霧する冷却方式は既にあるが、その方法と

ルによつている。 Generally speaking, there is already a cooling method that sprays gas and liquid as a method of cooling steel strips, but this method uses a blower to send the gas and a pump to send the liquid.
It is cooled by spraying it onto the steel strip in a mixed state. The cooling capacity is controlled by controlling the amount of gas and/or liquid and/or the number of spray nozzles.
この場合、気体と液体の両方をコントロールす
ることは、制御弁の数が多くなり不経済であるた
め、冷却効果への寄与の高い液量をコントロール
するのが通常の方法である。その際、液体ヘツダ
ーの元バルブを完全に閉塞しても気体は出ている
ため、その気体の霧吹効果により、液体ヘツダー
中の残液が吸上げられて霧化される、従つて冷却
の制御が充分でなく、鋼帯冷却に要求される所望
の終点温度が正確に得られない問題があつた。 In this case, since controlling both gas and liquid would increase the number of control valves and be uneconomical, the usual method is to control the amount of liquid that contributes most to the cooling effect. At this time, even if the main valve of the liquid header is completely closed, gas is still coming out, so the residual liquid in the liquid header is sucked up and atomized by the atomizing effect of the gas, thus controlling the cooling. There was a problem that the desired end point temperature required for cooling the steel strip could not be accurately obtained.
本考案は上述の問題を解決したものであつて、
その要旨は気体と液体とを圧力下に混合して気液
噴霧する鋼帯の冷却装置において、複数のノズル

イプを連通した点にある。 The present invention solves the above-mentioned problems.
The gist is that in a steel strip cooling device that mixes gas and liquid under pressure and sprays the gas and liquid, a drain pipe is connected to the vicinity of the end of a gas-liquid nozzle provided with a plurality of nozzle headers.
以下本考案を図面について説明する。 The present invention will be explained below with reference to the drawings.

る。 Figure 1 is a partial sectional view of a gas-liquid spray cooling device for a continuous annealing furnace for steel strips, Figure 2 is an overall explanatory diagram of the present invention,
FIG. 3 is a view taken along the line A--A in FIG. 2. In the figure, the exhaust port 4 of the gas chamber 1 is combined with the drain port 3 of the gas-liquid nozzle 2 at its tip to form a mixing portion. A desired number of the above-mentioned gas-liquid spray devices are provided in the passing direction of the steel strip to constitute a cooling device.
本考案の液抜き装置は、気液ノズル２の端部近

す。 In the liquid draining device of the present invention, a liquid drain pipe 5 is provided in communication with the vicinity of the end of the gas-liquid nozzle 2, but it is provided outside the width of the steel strip. Although it is easier to adjust the drainage rate if the valve 7 is heated, the purpose of the present invention can be achieved even without the valve 7. Reference numeral 6 indicates a water passage, and reference numeral 8 indicates a nozzle mounting portion.
気液ノズル２の内圧は、吹付ガス量および圧力
により異なるが、例えば−40mmAqになる。そこ
で液噴霧のバルブ閉により、液体ヘツダー中の水
面が、前記負圧値に等しくなる迄、噴霧が続くの
で、排水パイプ５の大きさ及び長さは、負圧値及
び排水すべき時間により設計されるとよい。例え
ば、上記負圧時に、気液ヘツダー容積６の場
合、排水すべき時間を８秒とすると、内径4.5mm
φ、長さ100mm程度の排水管が必要となる。 The internal pressure of the gas-liquid nozzle 2 varies depending on the amount and pressure of the blown gas, but is, for example, -40 mmAq. Therefore, by closing the liquid spray valve, spraying continues until the water level in the liquid header becomes equal to the negative pressure value, so the size and length of the drain pipe 5 are designed based on the negative pressure value and the time for draining water. It would be good if it were done. For example, at the above negative pressure, if the gas-liquid header volume is 6, and the time to drain is 8 seconds, the inner diameter is 4.5 mm.
A drain pipe with a diameter of approximately 100 mm is required.
以上本考案について説明したが、本考案による
と、気体噴霧の停止に伴い、液ノズルの残液は、
排液パイプで容易にヘツダーから排出されるの
で、鋼帯の水量及び噴霧時間の観点から、正確な
冷却を得て終点温度の制御が容易であり、その実
用的効果は大である。 The present invention has been explained above. According to the present invention, when gas spraying stops, the remaining liquid in the liquid nozzle is
Since the liquid can be easily discharged from the header with a drainage pipe, it is easy to obtain accurate cooling and control the end point temperature in terms of the amount of water in the steel strip and the spray time, and its practical effects are great.
