この発明は、鋼板材等の冷却装置に係り、特に
加熱炉等で加熱処理された比較的幅広い被処理鋼
板材に、その幅に応じて冷却剤の噴射範囲を調整
することで被処理鋼板材に最適な冷却処理を施し
得る鋼板材等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 steel plate materials, etc., and in particular, adjusts the injection range of coolant according to the width of a relatively wide steel plate material that has been heat-treated in a heating furnace or the like. The present invention relates to a cooling device for steel plate materials, etc., which can perform optimal cooling treatment on the steel plate material to be treated.
一般に加熱炉等で熱処理された鋼板材は、ロー
ラコンベア等によつて搬送されつつ冷却剤により
冷却処理されて、熱加工される。この冷却処理に
際して、冷却水を冷却剤として用いた冷却装置が
知られている。特に本発明にあつては、冷却剤と
して冷却水を用いた冷却装置に係るものである。 Generally, a steel plate material that has been heat treated in a heating furnace or the like is cooled with a coolant while being conveyed by a roller conveyor or the like, and then heat processed. Cooling devices that use cooling water as a coolant in this cooling process are known. In particular, the present invention relates to a cooling device that uses cooling water as a coolant.
従来、この種の鋼板材等を冷却する装置として
は、第１図に示すものが一般に使用されている。
この冷却装置は、図示するごとくローラコンベア
１を構成するローラ２の長手方向に沿つて、即ち
ローラコンベア１の幅方向に沿つてその上方部に
設けられている。 Conventionally, as a device for cooling this type of steel plate material, etc., the device shown in FIG. 1 has been generally used.
As shown in the figure, this cooling device is provided along the longitudinal direction of the rollers 2 constituting the roller conveyor 1, that is, along the width direction of the roller conveyor 1 at an upper portion thereof.
また、冷却装置３はローラ２の長手方向に沿つ
てその上方に亘つて設けられた給水管４と、この
給水管４のローラ２に臨んだ部分に且つローラ２
に沿つて所定の間隔を隔てて設けられた噴射ノズ
ル５と、給水管４を接続された給水系６とから主
に構成されている。 The cooling device 3 also includes a water supply pipe 4 provided along the longitudinal direction of the roller 2 and above the roller 2, and a portion of the water supply pipe 4 that faces the roller 2, and
It is mainly composed of injection nozzles 5 provided at predetermined intervals along the line, and a water supply system 6 to which a water supply pipe 4 is connected.
またローラコンベア１を構成するローラ２はそ
の両端部に軸受部７を備えており、ローラ２を回
転自在に支持され、ローラ２上の被処理鋼板材８
を搬送方向に沿つて移送する。 Further, the roller 2 constituting the roller conveyor 1 is provided with bearings 7 at both ends thereof, and the roller 2 is rotatably supported, and the steel plate material to be processed on the roller 2 is
is transported along the transport direction.
従つてローラ２上に搬送される被処理鋼板材８
は、噴射ノズル５から噴射される冷却水等の冷却
剤によつて冷却処理される。 Therefore, the steel plate material 8 to be treated is conveyed onto the rollers 2
is cooled by a coolant such as cooling water injected from the injection nozzle 5.
ところで、従来の冷却装置にあつては給水管４
に設けられた全ての噴射ノズル５から均一に冷却
水が噴射されるように構成されている。そこで、
冷却水等の冷却剤は被処理鋼板材８の幅の大きさ
に関係なく給水管４に設けられた全ての噴射ノズ
ル５から噴射されていた。 By the way, in the conventional cooling system, the water supply pipe 4
The structure is such that cooling water is uniformly injected from all the injection nozzles 5 provided in the. Therefore,
Coolant such as cooling water is injected from all the injection nozzles 5 provided in the water supply pipe 4 regardless of the width of the steel plate material 8 to be treated.
被処理鋼板材８がローラ２の長手方向に沿つた
幅よりも小さい場合には、被処理鋼板材８以外の
部分に冷却剤が噴射されてしまう。 If the width of the steel plate material 8 to be treated is smaller than the width along the longitudinal direction of the roller 2, the coolant will be injected onto parts other than the steel plate material 8 to be treated.
このように被処理鋼板材８に直接冷却剤を噴射
する以外にその鋼板材の端部から外方部分に冷却
水を噴射することは、その鋼板材の端部９がロー
ラ２等から反射された冷却剤によつてより冷却さ
れて鋼板材の冷却温度分布が不均一となり、好ま
しくない冷却処理がなされる傾向がある。 In this way, in addition to injecting the coolant directly onto the steel plate material 8 to be treated, injecting cooling water from the edge of the steel plate material to the outer portion is a problem in that the end portion 9 of the steel plate material is reflected from the roller 2 or the like. The cooling temperature distribution of the steel sheet material becomes non-uniform due to the cooling caused by the coolant, which tends to result in undesirable cooling treatment.
また、被処理鋼板材８以外の部分に冷却剤を噴
射することは給水系６のポンプ１０の動力損失を
招くと共に、直接ローラ２に冷却剤を噴射するこ
とはローラ２の酸化減量をひき起こすことや軸受
部７に不必要な冷却剤が流入しこれに悪影響をも
たらす。 In addition, injecting the coolant to parts other than the steel plate material 8 to be treated causes power loss of the pump 10 of the water supply system 6, and injecting the coolant directly to the roller 2 causes oxidation loss of the roller 2. In addition, unnecessary coolant flows into the bearing portion 7, which has an adverse effect on the bearing portion 7.
そこで従来の鋼板材等の冷却装置を改良し、鋼
板材の幅に応じて適切に冷却剤を噴射すべく冷却
装置が提案されるに至つている。この改良された
冷却装置は第２図に示すように、給水管４をロー
ラ２の長手方向に沿つて所定の大きさに分割した
ものである。それぞれの給水管４ａ，４ｂ，４ｃ
には分岐された給水系６ａ，６ｂ，６ｃが接続さ
れ、それぞれの給水系には流量調整弁１１ａ，１
１ｂ，１１ｃが設けられている。 Therefore, improvements have been made to conventional cooling devices for steel plate materials, etc., and cooling devices have been proposed to inject coolant appropriately depending on the width of the steel plate material. As shown in FIG. 2, this improved cooling device is constructed by dividing the water supply pipe 4 into predetermined sizes along the longitudinal direction of the roller 2. Each water supply pipe 4a, 4b, 4c
Branched water supply systems 6a, 6b, and 6c are connected to the water supply systems, and each water supply system has flow rate regulating valves 11a and 11a.
1b and 11c are provided.
従つて、被処理鋼板材８′の幅に応じてこれに
横切る給水管から冷却剤を噴射することによつて
冷却処理するように構成されている。 Therefore, the steel plate material 8' is configured to be cooled by injecting a coolant from a water supply pipe that traverses the steel plate material 8' depending on its width.
ところが、被処理鋼板材８′の幅が可変的であ
り、分割された給水管の組み合わせがそれに相応
しないことが起こる。例えば被処理鋼板材８′に
対して分割された給水管の幾つかではこれを被う
ことができなくなつたり、余剰が生じたりするこ
とがある。 However, the width of the steel plate material 8' to be treated is variable, and the combination of the divided water supply pipes may not be appropriate. For example, some of the water supply pipes divided into the steel plate material 8' to be treated may no longer be able to cover it, or there may be surplus water pipes.
また、流量調整弁で給水系からの給水をそれぞ
れの給水管の水圧を一定に制御することが難し
く、被処理鋼板材８′への冷却剤の噴射分布が不
均一になるおそれがある。特に、給水管と給水管
との分割部分における被処理鋼板材８′に不均一
な冷却処理がなされる問題がある。 In addition, it is difficult to control the water pressure of each water supply pipe from the water supply system to a constant level using a flow rate regulating valve, and there is a risk that the injection distribution of the coolant to the steel plate material 8' to be treated may become uneven. In particular, there is a problem in that the steel plate material 8' to be treated at the dividing portion between the water supply pipes is subjected to non-uniform cooling treatment.
そこで、それぞれの噴射ノズルに流量調整弁を
設けて被処理鋼板材の幅に相応させて冷却剤を噴
射することが考えられるが、この場合、調整弁の
制御が技術的に複雑になると共に鋼板材に対して
均一な冷却剤の噴射分布を形成することができな
い。 Therefore, it is conceivable to install a flow rate adjustment valve in each injection nozzle and inject the coolant according to the width of the steel plate to be treated, but in this case, the control of the adjustment valve becomes technically complex and the steel plate It is not possible to create a uniform spray distribution of coolant on the material.

By opening and closing an appropriate number of nozzles 5, the spray width of the coolant along the longitudinal direction of the water supply pipe 4' can be variably adjusted and controlled.
このように、冷却剤の噴射幅が被処理鋼板材の
幅に一致させることができるのでその冷却処理が
