CONSTITUTION:A lance is inserted into a nozzle by the rotation of a motor 27 for a lance and with a rotor 47 for feeding a lance, dependent body 28 for feeding a lance and support 28 for a lance, advanced while blowing oxygen, initial holing is executed by advancing the lance so as to always contact with a raw metal and smelting during piercing. After the supply of oxygen is stopped after piercing, the lance is retreated by reversing the motor 27. After that, the blow pipe is made to coincide with the initially opened hole with a traversing device 3, next advanced with a straight motion motor 17 and made to coincide with the tip of a lower nozzle. After that, smelting is started from the through hole with preheating gas and cutting oxygen and oscillating motion from the upper part to the lower part is executed to prevent the resolidification of the row metal and deterioration of refractory materials.

2. Description of the Related Art At present, a sliding nozzle device mounted on a ladle that handles molten steel is carried into a ladle servicing site in a closed state after completion of casting, and is maintained at this time. If not completely removed with gold,
It is conceivable that the molten steel will solidify and become clogged due to the residual metal at the time of the next casting, resulting in non-open holes. Therefore, this work is important and requires certainty. Therefore, as a conventional method of removing the metal, cleaning work by manually inserting an oxygen lance from the lower nozzle has been performed, but this is a dangerous work under high heat and a bad environment, and automation is desired. ing. However, this cleaning method requires a delicate technique of always contacting the tip of the lance with the metal and making it heat in a red-hot state, and at the same time, it frequently changes depending on the wear condition of the lance and the position of the metal. Was being adjusted.

As described above, it is dangerous work under extremely high heat and bad environment, and automation is desired, but mechanization of work requires complicated operation. It is difficult, and the reality is that it is not yet automated. Therefore, when considering automation,
Mechanization using a consumable lance requires constant measurement of the consumable state of the lance and the movement according to it, so the use of a non-consumable blow tube can be considered as an alternative means. However, even if cleaning is performed only with the non-consumable blowpipe, there is a risk of melting damage to the blown pipe due to blowback of the ablation flame to the object in the closed state.

Further, even when the through holes are present from the initial stage, the simple rotating motion makes it impossible to completely remove the adhering metal due to re-solidification, and the simple heating motion causes a local heating state, resulting in an injection nozzle. It causes deterioration of refractories.
In view of the above situation, the present invention is a cleaning method that automatically removes solidified metal that is clogged or stuck in the sliding nozzle hole and the injection nozzle hole of the sliding nozzle device installed at the bottom of the molten metal ladle. The purpose is to provide a device.

Further, as shown in FIG. 9, the lance of 26 is 2
By rotating the lance motor of No. 7 and 47, 28 and 48, the lance is inserted into the nozzle and advanced while releasing oxygen, and the lance is advanced so that it is always in contact with the metal during perforation, and is abraded. Perform initial opening. After the penetration, the supply of oxygen is stopped, and then the motor of 27 is reversed to retract the lance. After the initial opening by the lance, the blow tube is aligned with the initial opening hole by the traverse device 3 and then moved forward by the linear motor 17 and aligned with the tip of the lower nozzle.
At this time, the forward / backward movement is performed by driving the 17 linear motion motors by 18
To 16 arms and perform along 38 rollers. After positioning of the blow pipe, the fusing is started from the through hole by preheating gas and cutting oxygen, and in order to prevent re-solidification of the metal and deterioration of the refractory, as shown in FIG. Perform the rocking motion as shown.

This oscillating motion is equivalent to one rotation of twelve motors.
Transmission is carried out by 15 pulleys attached to 16 arms by 3 pulleys and 14 belts. Further, during the swinging movement, the direction of the blow tube is determined by the eccentric amount changing bolt 20 and the eccentric angle changing motor 21 before the work so as to determine the turning radius and the direction angle. Eccentricity change 4 with 20 bolts
The guide tube 6 moves the blow tube fixing portion 40. For changing the eccentric angle, the rotation of the motor 21 is rotated by the screw nut 22 to rotate the eccentric angle adjusting shaft 24 through the connecting portion of the front-back movement 23, and the angle 46 is changed.

After the cleaning is completed, the gas is stopped, the arm is retracted, and the traveling carriage 1 moves to the initial position. The direction of the blow pipe is adjusted during the cleaning by the above method, and the swing motion is performed by swinging the blow pipe so that the metal is accurately applied with the ablation gas as shown in FIG. This is to prevent re-solidification of the ground metal, to completely remove it, and to prevent deterioration of refractory materials such as the injection nozzle. If the metal remains after cleaning with this method, the arm is advanced and inserted into the nozzle so that the blow pipe approaches the metal.
