本発明は、製鋼設備におけるタンディツシュノズルの予
熱方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for preheating a tundish nozzle in steel manufacturing equipment.
溶鋼をタンディツシュからモールドに注入するために、
タンディツシュとモールドとの間全連結するノズルがタ

順調に行うためにはタンディツシュ本体およびノズルに

してノズル詰りか起る原因ともなる。In order to inject molten steel from the tundish into the mold,
A nozzle that fully connects the tundish and the mold is provided at the bottom of the tundish, but in order to smoothly inject molten steel, it is necessary to sufficiently preheat the tundish body and the nozzle. Otherwise, when the molten steel is transferred to the tundish, and furthermore, when it is transferred from the tundish to the mobled, it will be rapidly cooled, causing segregation noise, which will impair quality, and may solidify in the nozzle, causing nozzle clogging. It also causes it to happen.

、矢印は燃焼ガスの流れを示す。In this nozzle preheating method, conventionally, as shown in FIG. 2, preheating was carried out by separately introducing combustion gas for preheating the tundish main body and preheating combustion gas for the tundish nozzle. In the figure, 1 is a tundish, 2 is a tundish nozzle, 3 is a burner for preheating the tundish, and 4 is a preheating box, which is equipped with a tundish nozzle preheating burner 5 inside. As shown in the figure, the danditsh nozzle preheating burner 5 has a structure that surrounds the danditsh nozzle 2 and heats it from the outside.The arrows indicate the flow of combustion gas.
前記のような従来の方法には、次のような問題がある。 The conventional methods described above have the following problems.
１）タンディツシュ本体とタンディツシュノズルとを別
個に夫々予熱するため予熱用の燃焼ガスを多量に必要と
する。1) Since the tundish main body and the tundish nozzle are preheated separately, a large amount of combustion gas for preheating is required.
２）タンディツシュノズルの予熱が外部から行われるた
め、溶鋼が直接触れる肝心のノズル内面の予熱が十分で
なく、溶鋼注入初期のノズル詰りの原因となる場合があ
る。2) Since the tundish nozzle is preheated from the outside, the essential inner surface of the nozzle, which comes into direct contact with molten steel, is not sufficiently preheated, which may cause nozzle clogging at the initial stage of molten steel injection.
本発明は上記の問題点を解決するために、タンディツシ
ュノズルを予熱ボックスで囲い、該予熱ボックスの一方
の端からイジェクタ一方式で内部よりガス全吸引させる
ようにして、タンディツシュ本体の予熱を行う方法を提
供するものである。In order to solve the above problems, the present invention surrounds the tundish nozzle with a preheating box, and preheats the tundish main body by sucking all the gas from inside using an ejector from one end of the preheating box. The present invention provides a method.
タンディツシュ本体を予熱した燃焼ガスは、タンディツ

タンディツシュノズルの出ロヲ抜けて予熱ボックス内に

より、溶鋼の直接触れる部分がすべて十分に予熱される
。The combustion gas that has preheated the tundish body is sucked into the tundish nozzle, and when the molten steel passes, it passes through the exit of the tundish nozzle through the same path and enters the preheating box, where it is sucked from one end of the preheating box. By doing so, all parts that come into direct contact with molten steel are sufficiently preheated.

続されている。FIG. 1 is a schematic diagram showing the overall configuration of an embodiment of the present invention. In the figure, a burner filter for preheating the tundish is provided above the tundish 1, and a tundish nozzle 2 at the bottom of the tundish 1 is surrounded by a preheating box 4, and one opening of the preheating box 4 is connected to an ejector. It is connected to a one-sided suction device (not shown).

ィツシュノズル２の内面は予熱が完全に行われることに
なる。Next, this effect will be fully explained. The combustion gas that is blown onto the inner surface of the tundish 1 by the tundish preheating burner 6 and preheats the inner surface of the tundish 1 follows the inside of the tundish nozzle 2 due to the suction action, and enters the preheating box 4 from the outlet of the tundish nozzle 2. It flows out into the interior and is further drawn into the suction device through one of the ports and discharged. As a result, the inner surface of the tundish 1 and the inner surface of the tundish nozzle 2 are completely preheated.

する効果がある。According to the present invention, by sucking all the preheated waste gas from the tundish main body into the tundish nozzle and preheating it, combustion gas for preheating the tundish nozzle is not required, and the tundish nozzle directly comes into contact with molten steel. Since preheating proceeds from the inside, it has the effect of significantly improving preheating efficiency.
