Field of the Invention The present invention, when collecting a sample of molten metal such as molten steel, makes it possible to collect a high-purity sample without contamination, and also enables use in an existing automatic dipping device. The present invention relates to a sampling device.

Description of the Related Art In recent years, the number of high-grade steel grades has increased in the steel industry, and the carbon content of ultra-low carbon steel grades tends to become extremely low-carbon. Therefore, in the refining process, when a sample of such molten steel is sampled and the components in the sample are analyzed, the carbon content must be analyzed with high accuracy. It is necessary to be able to collect a sample of high purity.

含有率を不当に大きくしてしまうからである。By the way, in the case of a conventionally well-known probe, since the probe main body is constituted by a paper tube and the sampling container is provided inside the probe main body, it is possible to use a high-grade steel such as the above-mentioned ultra-low carbon steel. Not suitable for taking samples. Since the paper tube that composes the probe body burns while it is covered and immersed in molten steel, molten steel contaminated by this combustion gas, etc. flows into the sampling container and the carbon content in the sample is unduly increased. Because I will do it.

のである。On the other hand, conventionally, when a molten steel sample is taken by immersing the probe in molten steel, or when measuring the molten steel temperature or the oxygen in the molten steel, the probe is soaked in order to improve work safety and efficiency. An automated automatic dipping device is used and is known as disclosed in Japanese Patent Publication No. 52-28085. That is, this automatic dipping device, with a plurality of probes stacked in a filling case,
The lowermost probe is pulled out by the cutting device and dropped onto the transport device, and after the dropped probe is transported to the mounting device by the transport device, the probe is received by the receiving member in the mounting device and gripped by the chucking means. In this state, the probe is held upright, a dip lance descending from above is inserted into the probe held upright, and then the probe is lowered together with the dip lance to immerse in the molten steel.

い高純度の試料を採取できる。SUMMARY OF THE INVENTION In order to collect samples of high grade steels such as ultra low carbon steels as described above, the present inventors have proposed a simple ladle type sampler having no cause of molten steel contamination. It was found to be the most advantageous. Such a ladle-type sampler has a configuration in which an upper opening cup-shaped container is attached to the tip of a long handle, as disclosed in JP-B-53-26151 and JP-B-57-120253. Since the container is immersed in molten steel through the soaker, and so-called a sample is collected by so-called sampling, a high-purity sample without contamination can be collected.

困難であるという問題を有する。However, needless to say, since the ladle-type sampler is intended for manual sampling work, not only the work efficiency cannot be improved, but also severe work is required in a dangerous environment. . Further, since the operation is performed manually, there are variations in the immersion depth and time of the container, which makes it difficult to repeatedly take a sample under the same conditions.

ある。Therefore, it would be ideal if the sampling operation could be automated by using the existing automatic dipping device as described above while using such a ladle type sampler as a basic structure.
Unfortunately, the existing automatic dipping device has a problem that it cannot be applied to a ladle-type sampler because it is intended for a probe formed into a predetermined cylindrical shape by a paper tube.

な観点から決して好ましくない。Regarding this point, the above ideal can be realized by newly developing an automatic dipping device for a ladle-type sampler. However, many existing furnaces are designed for the cylindrical probe as described above. Since the old automatic dipping device was installed, when introducing a new device,
Old equipment must be taken out of service or discarded, which is never desirable from an economic perspective.

に適した装置を提供できるという効果がある。According to the present invention, the probe body 1 has the tail end portion formed in a cylindrical shape, and the exterior member 16 at the tip end portion.
Since it is formed into a cylindrical shape, it is possible to perform automatic insertion into the immersion lance 8 using an existing conventional automatic immersion device and automatic immersion into the molten metal by the immersion lance 8. When the immersion lance 8 is automatically inserted, the exterior member 16 can be automatically detached from the probe main body 1 by interlocking with the insertion of the immersion lance 8, so that the tip of the probe main body 1 can be attached before the immersion. The ladle-type sampler 12 can be projected in an exposed state, and the container 13 can be positioned at a position away from the probe main body 1 via the handle 14. From this state, the immersion lance 8 is lowered and immersed in the molten metal. A sample of high-purity molten metal that is not affected by contamination can be collected. As a result, there is an effect that it is possible to provide an apparatus suitable for sampling high-grade steel grades such as ultra-low carbon steel while using the existing automatic dipping apparatus.
