According to a first aspect of the present invention, there is provided a converter sub-lance metal removing device, wherein the converter sub-lance is guided by a guide member so as to be able to move up and down. The vibration applying means applies vibration to the sub-lance to remove the metal adhered to the sub-lance. When vibration is applied to the sub-lance by the vibration applying means while the sub-lance is inserted into the insertion opening of the hood of the converter, the molten metal adhered to the surface of the sub-lance separates from the sub-lance and falls into the converter. Therefore, the metal on the surface of the sublance can be easily removed. However, even when the sub-lance is pulled out of the converter, the metal adhered to the surface of the sub-lance can be removed by applying vibration to the sub-lance.

The vibration applying means may be a means for mechanically generating vibration by hitting the sub-lance from both sides or one side, or a means for generating vibration by electromagnetic force.
The vibration may be generated by other vibration generating means, or a combination of the above various types may be used. In short,
Any device that can generate vibration and add the vibration to the sublance may be used. Further, the vibration applying means may be provided on the guide member, or may be provided near the insertion opening of the exhaust gas hood of the converter.

When raising and lowering the sub-lance, the sub-lance can be guided by a pair of guide rollers. When the pair of guide rollers is opened and closed by opening and closing drive means, the pair of guide rollers hits the sub-lance and vibration is applied to the sub-lance. The metal that has been added and adhered to the sublance is removed.

At this time, a configuration may be adopted in which a pair of guide rollers applies a symmetrical impact from both sides of the sub-lance, in which case the sub-lance is not displaced to one side.
However, it is also possible to adopt a configuration in which a pair of guide rollers applies a blow from both sides of the sub-lance asymmetrically (shift of the timing of the blow or shift of the position up and down). When the vibration applying means is not operated, the pair of guide rollers can be kept in contact with the sub-lance, and can be effectively used for guiding the sub-lance. Other operations are the same as those of the first aspect.

According to a third aspect of the present invention, there is provided a converter sub-lance metal removing apparatus according to the first or second aspect of the invention, wherein the vibration applying means is driven up and down to switch the position of the vibration applying means in the height direction. A driving means is provided. Since the vibration state of the lower part of the sub lance changes according to the height position where vibration is added to the sub lance, the vibration driving means is moved by the elevation drive means so that the sub lance is positioned in the height direction suitable for removing the metal. Can be switched, and the metal removal performance can be enhanced.
Further, by changing the height position of the vibration applying means, it is possible to directly hit the adhered metal to improve the removal performance. Other effects are the same as those of the first or second aspect.

According to a fourth aspect of the present invention, there is provided an apparatus for removing metal from a sub-lance for a converter, wherein the actuator of the opening / closing drive means comprises a fluid pressure cylinder. Therefore, the driving force of the opening / closing drive means can be generated by the fluid pressure cylinder having a simple configuration, and a strong driving force can be generated. Other effects are the same as those of the second aspect. The metal removal device for a sub-lance for a converter according to claim 5,
The invention according to claim 2 is characterized in that the actuator of the opening / closing drive means comprises an electric motor. Therefore, the opening / closing drive unit can be operated at high speed by the electric motor. Other effects are the same as those of the second aspect.

According to a sixth aspect of the present invention, in the apparatus of the first aspect, the vibration applying means comprises:
At least one electromagnetic vibration generating means is provided. When the main body of the electromagnetic vibration generating means is fixed to a portion other than the sub-lance, and the output portion of the electromagnetic vibration generating means is arranged in contact with the sub-lance to operate the electromagnetic vibration generating means, vibration is applied to the sub-lance. In addition, since high-speed vibration can be generated, the efficiency of metal removal can be enhanced, and various vibrations (vibrations having different frequencies, vibrations having different strengths, etc.) can be performed through drive control for driving the electromagnetic vibration generating means. Can be generated, and a vibration suitable for removing the metal of the sublance can also be selected. Further, the configuration of the vibration applying means is simplified and downsized, which is advantageous in terms of equipment cost.

2 does not open and close, and both lever members 31,
32 will operate substantially synchronously and substantially symmetrically. The timing at which the guide rollers 35 and 36 strike the sublance 5 does not need to completely coincide with each other, and there is no problem even when the guide rollers 35 and 36 strike at a timing slightly shifted. And Sublance 5
The vibration behavior of the lower part of the sub-lance 5 changes depending on the position in the height direction where vibration is applied to the lower lance 5, and according to the weight of the probe 15 connected to the lower end of the sub-lance 5.

And the sub lance 5 are switched to the standby position, and the probe 1
The metal 5 is removed, and the metal removing device 20 can be applied to remove the metal slightly attached to the surface of the sublance 5 at the standby position. At this time, the metal is removed by applying vibration to the sub-lance 5 in the same manner as described above.
5, the height direction position of the lifting platform 21 (that is, the height direction positions of the guide rollers 35 and 36) is gradually changed, and the solidified metal is directly hit on the surface of the sub-lance 5 to directly hit the ground. Gold removal can also be performed. However, at the standby position, the metal removal may be performed while changing the height position of the sub-lance 5 via the winch and the wire 10.

As described above, since the molten metal can be removed while the sub lance 5 is inserted into the converter 1, the metal can be removed efficiently, and there is no need to collect the removed metal. . In addition, the pair of guide rollers 35 and 36 are effectively used, and the pair of lever members 31 and 32 are opened and closed by the pneumatic cylinder 40, so that the pair of guide rollers 3
Since the vibrations are applied by repeatedly applying the impacts at 5, 36, the configuration of the bullion removing device 20 is simplified and downsized, and the equipment cost is also advantageous.

Since the pair of guide rollers 35 and 36 strike both sides of the sub lance 5, the lower portion of the sub lance 5 does not displace to one side and the sub lance 5 collides with the insertion opening 8. Not even. In a state where the bullion removing device 20 is not used, the pair of guide rollers 35 and 36 can be used as original guide rollers. Since the height position of the vibration applying mechanism 30 can be switched by the pneumatic cylinder 40,
It is also possible to improve the slag removal performance. Since the pneumatic cylinder 40 is applied as an actuator of the opening / closing drive means for opening and closing the pair of lever members 31 and 32, the driving force can be generated by the pneumatic cylinder having a simple configuration.
