この発明は、ロングノズル内面に付着した地金
を洗浄するための地金洗浄用バーナーに関するも
のである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a metal cleaning burner for cleaning metal adhered to the inner surface of a long nozzle.
連続鋳造法において、タンデイツシユへの溶鋼
の供給は、第１図に示されるように、取鍋（図示
せず）の底部に取付けられたコレクターノズル１
に圧接されたロングノズル２を介して行なわれて
いる。 In the continuous casting method, molten steel is supplied to the tundish through a collector nozzle 1 attached to the bottom of the ladle (not shown), as shown in FIG.
This is done through a long nozzle 2 that is pressed into contact with the
上記ロングノズル２の特に、上部内面には、鋳
込の進行につれて地金が付着するので、鋳込終了
後に付着した地金をロングノズル面から除去する
必要がある。 As the casting progresses, the base metal adheres to the long nozzle 2, particularly to the upper inner surface thereof, so that it is necessary to remove the adhered base metal from the long nozzle surface after the casting is completed.
従来、地金の除去は、人手により酸素をパイプ
によつてロングノズル内面に吹付けることにより
行なつていた。 Conventionally, metal removal has been carried out manually by spraying oxygen onto the inner surface of a long nozzle through a pipe.
しかし、このような除去方法では、局部的な洗

この結果、鋼品質に悪影響を及ぼすとともに、ロ
ングノズルの温度が低下するので、次の溶鋼鋳込
時に地金の付着量が増加する。 However, with this removal method, only local cleaning can be performed, so cleaning takes a long time. If cleaning takes a long time, it will take time to pour the next molten steel into the tundish, and during this time the amount of molten steel in the tundish will decrease, so molten steel containing many inclusions will be poured into the mold.
As a result, the quality of the steel is adversely affected and the temperature of the long nozzle decreases, which increases the amount of metal deposited during the next pouring of molten steel.

ることに特徴を有する。 From the above-mentioned viewpoints, the present invention provides a cleaning burner that can reliably remove metal attached to the inner surface of a long nozzle in a short period of time without manual intervention, and has a plurality of oxygen discharge ports, A cylindrical burner main body that is inclined outward with respect to the axis and is bored in a circular arrangement, a ring-shaped fixed metal fitting having an inner diameter larger than an outer diameter of the burner main body, and an axial center of the fixed metal fitting. It is characterized in that it is comprised of a plurality of fixing screws that penetrate toward the fixing hardware and are screwed into the fixing hardware, and a ring-shaped mounting plate fixed to the outer peripheral surface of the fixing hardware.
この発明の一態様を図面を参照しながら説明す
る。 One embodiment of the present invention will be described with reference to the drawings.
第２図は、この発明の一態様を示すバーナーの
断面図、第３図は、同正面図である。 FIG. 2 is a sectional view of a burner showing one embodiment of the present invention, and FIG. 3 is a front view thereof.

外方に向けて傾斜している。 At the tip of the burner body 3, a plurality of oxygen discharge holes 3a are arranged in a circular shape, and at the center of the rear end, an oxygen supply hole 3b is formed. A hollow chamber 3c is formed. Therefore, the oxygen supplied into the burner body 3 from the oxygen supply hole 3b passes through the hollow chamber 3c and is simultaneously discharged in a ring shape from each discharge hole 3a. Each discharge hole 3a is slightly inclined outward with respect to the axis of the burner body 3.

調整することができる。 In the fixing hardware 4, insert four fixing screws 6 toward the center.
penetrates the fixed hardware 4 and is screwed together. The inner diameter of the fixed hardware 4 is slightly larger than the outer diameter of the burner body 3. Therefore, a gap is formed between the burner body 3 inserted into the fixed hardware 4 and the fixed hardware 4. By adjusting the fixing screw 6, the burner main body 3 can be adjusted in position vertically and horizontally with respect to the fixed hardware 4.

ノズル２の上面の寸法とほぼ等しい。 A flange 5a extending perpendicularly downward is formed on the outer edge of the mounting plate 5, and prevents the mounting plate 5 from shifting in the left-right direction after the mounting plate 5 is placed on the long nozzle. . The width dimension of the mounting plate 5 is approximately equal to the dimension of the upper surface of the long nozzle 2.

で、地金７は一度に除去洗浄される。 In order to wash and remove the metal deposited inside the long nozzle using the burner configured as described above, the burner main body 3 is inserted into the fixed hardware 4 and temporarily fixed with the fixing screw 6. Thereafter, as shown in FIG. 4, the burner main body 3 is installed on the long nozzle 2 by placing the mounting plate 5 on the long nozzle 2. Next, adjust the fixing screw 6 of the fixing hardware 4 to adjust the position of the burner body 3 in the vertical and horizontal directions, so that the burner body 3 is connected to the long nozzle 2.
Each discharge hole 3a is made to face the base metal 7 attached to the long nozzle 2 without contacting the long nozzle 2. Thereafter, the valve 9 of the oxygen supply pipe 8 connected to the oxygen supply hole 3b of the burner body 3 is opened to discharge oxygen toward the base metal 7 from the discharge hole 3a. Since oxygen is discharged from each discharge hole 3a in a ring shape to the base metal 7 all at once, the base metal 7 is removed and cleaned at once.
