内の水位が一定に保たれるようになっている。A pipe 4 opened to a water tank 8 via a pump 6 is connected to a spray nozzle 2 for cooling the mold 1, and cooling water is blown from the spray nozzle 2 to the mold 1. When the pipe 5 opened to the elevated water tank 7 and provided with the emergency valve 11 is connected to the pipe 4, and a failure occurs in the normal water supply system supplied from the pipe 4 via the water tank 8 and the pump 6. Then, the emergency valve 11 is opened, emergency cooling water is supplied to the pipe 4 via the pipe 5 by the head of the elevated water tank 7, and cooling water is supplied to the mold 1 from the spray nozzle 2. In the figure, reference numeral 9 denotes a pipe branched from the downstream side of the pump 6 of the pipe 4 to supply water to the elevated water tank 7, and the elevated water tank 7 is connected to the water tank 8 by a bypass pipe 10, and Aquarium 7
The water level inside is kept constant.

冷却水がモールドに供給される時、給水系の切換わる時
間遅れによって給水が一時的に止る現象が起る。In the conventional cooling method of the continuous casting mold described above, when water supply from the water tank is stopped due to an accident such as a power failure and emergency cooling water is supplied to the mold, water supply is performed due to a time delay when a water supply system is switched. A phenomenon that stops temporarily occurs.
スプレ冷却モールドの場合、給水が一時的にでも止る
と水圧が下って冷却能力が急激に低下してモールドが溶
損する危険性がある。In the case of the spray cooling mold, if the supply of water is stopped even temporarily, there is a danger that the water pressure will drop and the cooling capacity will drop sharply, causing the mold to melt.
本発明は、上記従来の冷却方法の欠点を解決して非常

高架水槽内の水が連鋳用モールドに吹付けられる。In the present invention, cooling water having sufficient heat and water pressure to solidify the molten steel is sprayed from the steady spray nozzle onto the continuous casting mold by a pump. On the other hand, from the emergency spray nozzle, the water in the elevated water tank is sprayed onto the continuous casting mold by the head of the water in the elevated water tank.

続行され、連鋳用モールドの溶損が防がれる。During a normal operation, the cooling water from the emergency spray nozzle is constantly sprayed on the continuous casting mold together with the cooling water from the above-mentioned normal spray nozzle. Even if the pump stops due to an accident such as a power outage and the cooling water from the normal spray nozzle stops, the cooling water from the emergency spray nozzle continues to be sprayed on the continuous casting mold to continue cooling the continuous casting mold. Thus, erosion of the continuous casting mold is prevented.

い程度の量となるようにされている。An emergency spray nozzle 3 is provided in addition to a plurality of stationary spray nozzles 2 to which cooling water is supplied from a pipe 4, and the spray nozzle 3 is connected to an elevated water tank 7 by a pipe 5. That is, in the system shown in FIG. 2, the pipe 5 is connected to the pipe 4, but in this system, the pipe 5 is not provided with an emergency valve, and is connected to the emergency spray nozzle 3. Further, the amount of water spouted from the emergency spray nozzle 3 is set to an amount that does not damage the mold.
上記以外の点は、第１図に示される装置は第２図に示
される従来装置と同じ構成を有している。Except for the above points, the device shown in FIG. 1 has the same configuration as the conventional device shown in FIG.

ド１に噴出される。このとき、給水ポンプ６により加圧
され高圧，大量の冷却水が送られる。In this embodiment, the water tank 8 is normally operated by the pump 6.
The water in the inside is jetted from the spray nozzle 2 for steady state to the mold 1 as cooling water. At this time, the water is pumped by the water supply pump 6 to send a high pressure and a large amount of cooling water.
一方同時に、高架水槽７の高さによって決る圧力とモ
ールド１が溶損しない程度の量の冷却水が非常用スプレ
ノズル３より供給される。At the same time, the emergency spray nozzle 3 supplies pressure determined by the height of the elevated water tank 7 and cooling water in such an amount that the mold 1 is not melted.

る。Even if a failure such as a power failure occurs in the water supply system that sends the cooling water to the steady-state spray nozzle 2 and the pump 6 stops, the cooling water is continuously supplied to the emergency spray nozzle 3 by the water head in the elevated water tank 7. Then, the mold is cooled by an amount of cooling water that does not damage the mold 1, and the melt damage can be prevented.

ことが適当である。According to experience, the amount of cooling water supplied from the emergency spray nozzle 3 only needs to be about 1/3 of the amount of cooling water supplied from the regular spray nozzle 2, and the amount of the emergency cooling water is 20%. If it is supplied for about a minute, it is possible to escape from the very situation. Therefore, it is appropriate to determine the emergency cooling water system including the emergency spray nozzle 3, the pipe 5, the elevated water tank 7, and the like based on this standard.

れる。The present invention sprays cooling water supplied by a pump from a steady-state spray nozzle onto a continuous casting mold, and uses the water in the elevated spray tank as the cooling water for the continuous casting from the emergency spray nozzle by the head of water in the elevated water tank. Because the mold is sprayed, even if the pump stops due to an accident such as a power outage and the cooling water from the normal spray nozzle stops, the cooling water from the emergency spray nozzle continues to blow to the continuous casting mold. Attached. Therefore, there is no discontinuity in heat removal due to a time delay as in the conventional method. Therefore, according to the present invention, it is possible to prevent a mold melting accident at the time of a power failure or the like, and to guarantee safe operation of the continuous casting machine.
