【考案の詳細な説明】 〔産業上の利用分野〕 本考案は、溶湯を中空の加熱装置から鋳塊として連続的
に引き出すようにする連続鋳造装置に関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a continuous casting device for continuously drawing molten metal as an ingot from a hollow heating device.
近年、良質な材質の鋳塊を得るために使用される連続鋳

タンディッシュ３を経て加熱鋳型４に導き、当該中空の
加熱鋳型４の出口から鋳塊６として引出している。その
際、鋳塊６は冷却装置５から噴射される冷却水Ｗによっ
て冷却されながら引出装置７によって連続的に引出され
る。In recent years, continuous casting equipment used to obtain an ingot of high quality material guides a molten metal 2 in a crucible 1 to a heating mold 4 through a tundish 3 as shown in FIG. An ingot 6 is drawn out from the outlet of the mold 4. At that time, the ingot 6 is continuously drawn by the drawing device 7 while being cooled by the cooling water W jetted from the cooling device 5.
上記の冷却装置５は、第４図のように、丸型ノズル5Aに
孔径の小さい数個のノズル孔5Bを放射状に設けることに
より構成されており、各ノズル孔5Bより鋳塊６に向けて
冷却水Ｗを噴出させている。As shown in FIG. 4, the cooling device 5 described above is configured by radially providing several nozzle holes 5B having a small hole diameter in the round nozzle 5A, and each nozzle hole 5B is directed toward the ingot 6. The cooling water W is ejected.
しかし、鋳塊６の冷却ゾーンZ1は斜線で示すように非常
に狭い部分である。例えば、この鋳塊６を径12mmの丸棒
とし、ノズル孔5Bの径を1.0mmとした場合の冷却ゾーンZ
1は、約２〜3mm程度であり、冷却効率が非常に悪い。こ
の種の連続鋳造設備における冷却能力は冷却水Ｗの圧力
や流量よりも加熱鋳型４から冷却装置５の冷却位置まで
の距離、及び冷却ゾーンの広さが大きく影響されること
が知られている。However, the cooling zone Z 1 of the ingot 6 is a very narrow portion as shown by the diagonal lines. For example, when the ingot 6 is a round bar with a diameter of 12 mm and the diameter of the nozzle hole 5B is 1.0 mm, the cooling zone Z
1 is about 2 to 3 mm, and the cooling efficiency is very poor. It is known that the cooling capacity in this type of continuous casting equipment is more greatly affected by the distance from the heating mold 4 to the cooling position of the cooling device 5 and the width of the cooling zone than the pressure and flow rate of the cooling water W. .
一方、この冷却水Ｗが高温の鋳塊６に当たることによっ
て発生する蒸気や水滴が加熱鋳型４側に流れると、加熱
鋳型４を冷却することになるので絶対に避けなければな
らない。On the other hand, if steam or water droplets generated when the cooling water W hits the hot ingot 6 flows to the heating mold 4 side, the heating mold 4 will be cooled and must be absolutely avoided.
本考案は、係る従来の問題点を解消するためになされた

とを目的とするものである。The present invention has been made to solve the above conventional problems, and efficiently cools an ingot drawn from a hollow heating mold, and steam or water droplets generated during cooling flows to the heating mold side. It is an object of the present invention to provide a continuous casting device that does not have such a problem.

る。The continuous casting device of the present invention for achieving the above object is
In a continuous casting device configured to cool the ingot by a cooling device arranged on the downstream side of the heating mold while continuously drawing the ingot from a hollow heating mold, the ingot passes through the cooling device. And a slit-shaped nozzle hole along the moving direction of the ingot, and the nozzle hole is inclined toward the moving direction of the ingot. At the same time, it is characterized in that it is directed in the tangential direction of the ingot.

する冷却ゾーンも大幅に広くなる。That is, when the cooling water is jetted from the slit-shaped nozzle holes that are inclined in the drawing direction of the ingot and are spirally arranged, a swirl is generated in the passage of the cooling device, which is generated around the ingot. The steam and water droplets are swirled and flow in the direction of pulling out the ingot. Further, since the inlet side of the cooling device has a negative pressure and the air in the room is drawn into the passage of the cooling device, steam and water droplets generated in the cooling device are further prevented from flowing to the heating mold side. Also, the cooling zone for the ingot is significantly widened.
以下、図面を参照して本考案の実施例を説明する。 Embodiments of the present invention will be described below with reference to the drawings.

る。FIG. 1 is a sectional view of a main part of a continuous casting apparatus according to the present invention. A cooling device 15 is a cooling water W on the outer periphery of an ingot 6 drawn downward from a heating mold 4 in the continuous casting equipment of FIG. Is provided for cooling by spraying downward.

斜している。As shown in FIG. 2, the cooling device 15 has a tubular shape and faces the passage 17 of the nozzle 16 and has a large number of slit-shaped nozzle holes 18.
Are arranged in a spiral pattern. Each nozzle hole 18 has a first
As shown in the figure, it is vertically long, and is inclined diagonally downward.
各ノズル孔18は、第１図に示すように、下向き角θ1を
有しており、また、第２図に示すように、渦巻角θ2を
有している。なお、各ノズル孔18は鋳塊６の接線上に位
置させることが望ましい。Each nozzle hole 18 has a downward angle θ 1 as shown in FIG. 1 and a swirl angle θ 2 as shown in FIG. It is desirable that each nozzle hole 18 be located on the tangent line of the ingot 6.
符号19は各ノズル孔18を連通させるために各ノズル孔18

冷却水供給孔である。Reference numeral 19 indicates each nozzle hole 18 in order to communicate each nozzle hole 18.
An annular passage 20 is provided on the back surface of the cooling passage, and 20 is a cooling water supply hole communicating with the passage 19.
そして、下向きに傾斜し、かつ、スパイラル状に配設さ

塊に対する冷却ゾーンZ2も従来に比べて大幅に広くな
る。When the cooling water W is jetted from a large number of slit-shaped nozzle holes 18 which are inclined downward and are arranged spirally, a swirl is generated in the passage 17 of the nozzle 16 and the periphery of the ingot 6 is generated. The steam and water droplets generated in 1 flow in the withdrawal direction of the ingot 6 while being wound in a spiral shape. Further, since the inlet side of the passage 17 has a negative pressure and the air in the room is drawn into the passage 17, steam and water droplets generated in the nozzle 16 are heated.
It will be further blocked from flowing to the side. Also, the cooling zone Z 2 for the ingot is significantly wider than in the conventional case.
上記のように、本考案によれば、冷却装置の通路内に渦

になる。また、鋳塊に対する冷却ゾーンも従来に比べて
大幅に広くなる。As described above, according to the present invention, a vortex flow is generated in the passage of the cooling device, and the steam and water droplets generated around the ingot flow not only in the drawing direction of the ingot while swirling, but also in the cooling device. The inlet side becomes negative pressure, and the air in the room is drawn into the passage of the cooling device, so that steam and water droplets generated in the cooling device are prevented from flowing to the heating mold side. Also, the cooling zone for the ingot is significantly wider than in the conventional case.
したがって、冷却装置内で発生した蒸気や水滴が上流の

させることもできる。Therefore, there is no possibility that steam or water droplets generated in the cooling device will flow to the upstream heating mold side to cool the heating mold, and a high quality ingot can be obtained. Further, since the distance from the heating mold to the cooling position by the cooling device can be shortened and the cooling capacity in the continuous casting equipment can be increased, the casting speed can be increased.
