【考案の詳細な説明】
本考案は熱間圧延された圧延材を冷却するラミ
ナフロースプレイノズルの改良に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a laminar flow spray nozzle for cooling hot rolled rolling stock.
熱間圧延設備において仕上圧延機を出た高温の
ストリツプはランナウトテーブル上を走行中に所
定の温度まで冷却されてダウンコイラに巻き取ら
れており、この冷却のいかんによつて製品品質が
大きく影響される。 In hot rolling equipment, the high-temperature strip that leaves the finishing mill is cooled down to a predetermined temperature while running on a runout table and then wound into a down coiler, and the quality of the product is greatly affected by how well the strip is cooled. Ru.
そこで、均一かつ能率良く冷却できることから
冷却水を層流状態でスプレイするラミナフロー冷
却が広く用いられており、例えば第１図あるいは
第２図に示すように、給水管１に接続された箱状
のヘツダ２の側方あるいは丸形のヘツダ２の下端
に圧延材の幅方向と平行に２枚のノズルプレート
を組合せてわずかなノズル間隙δをあけた断面矩
形のスプレイノズル３が取付けられ、給水管１を
介してヘツダ２に供給される冷却水を層流状態で
スプレイするようにしている。 Therefore, laminar flow cooling, which sprays cooling water in a laminar flow state, is widely used because it can cool uniformly and efficiently.For example, as shown in Fig. 1 or 2, a box-shaped A spray nozzle 3 with a rectangular cross section is installed on the side of the header 2 or at the lower end of the round header 2 in parallel with the width direction of the rolled material by combining two nozzle plates with a slight nozzle gap δ. The cooling water supplied to the header 2 through the header 1 is sprayed in a laminar flow state.
ところが、通常スプレイノズル３のノズル間隙
δは５〜10mm程度と微少なことや製鉄所等で供給
される冷却水は循環使用されるのが一般的で水質
が次第に悪化すると共にゴミ等の混入も多いこと
から頻繁にノズル詰りを起してしまう。このため
水流や水量の確保が難しく冷却能力の維持が困難
となり、短期間毎にノズルに詰つたゴミや内面に
付着した水あか等を清掃しなければならない。 However, the nozzle gap δ of the spray nozzle 3 is usually as small as 5 to 10 mm, and the cooling water supplied to steel mills is generally used in circulation, which gradually deteriorates the quality of the water and causes the contamination of dust, etc. Due to the large number of them, nozzle clogging occurs frequently. For this reason, it is difficult to secure the flow and amount of water, making it difficult to maintain the cooling capacity, and it is necessary to clean the nozzle of dust and water scale adhering to the inner surface every short period of time.
この清掃を行なうにもスプレイノズルのノズル
間隙が微少である上に上下方向の長さが300〜500
mmと長くしかも上部にはヘツダ等が位置するため
スプレイノズルの下側から薄刃等の特殊な清掃用
具を挿入する必要があり、多大な労力と時間とを
費やしている。 Even when performing this cleaning, the nozzle gap of the spray nozzle is minute and the length in the vertical direction is 300 to 500 mm.
Since the spray nozzle is long (about 1.5 mm) and has a header etc. located at the top, it is necessary to insert a special cleaning tool such as a thin blade from the bottom of the spray nozzle, which requires a great deal of labor and time.
一方、冷却能力はスプレイノズルのノズル間隙
が最も重要な因子であるが、使用される熱間圧延
設備と供給される冷却水圧力、温度、流量等とが
決まると、これらのデータに基づき最適にノズル
間隙を設計製作しており、冷却水源の仕様変化や
圧延材の種類の変化等に対応して冷却能力を変え
ることができないという欠点がある。 On the other hand, the most important factor for cooling capacity is the nozzle gap of the spray nozzle, but once the hot rolling equipment to be used and the supplied cooling water pressure, temperature, flow rate, etc. are determined, the optimum cooling capacity can be determined based on these data. The nozzle gap is designed and manufactured, and the drawback is that the cooling capacity cannot be changed in response to changes in the specifications of the cooling water source or the type of rolled material.

特徴とする。 The present invention aims to eliminate such conventional drawbacks and provide a laminar flow spray nozzle that is easy to clean and whose cooling capacity can be adjusted. The structure of the present invention that achieves this object is that, in a laminar flow spray nozzle that is attached to a header and sprays in a laminar flow state, there is a fixed nozzle plate whose upper end is fixed to the header, and a fixed nozzle plate whose upper end is opposite to the fixed nozzle plate. a movable nozzle plate which is movably supported and connected to the fixed nozzle plate, and a packing having a thickness corresponding to the nozzle gap interposed at the connecting portion between the fixed nozzle plate and the movable nozzle plate. It is characterized by being composed of.
