に示す。(Prior Art) In a metal refining process, it is necessary to appropriately collect a molten metal sample, analyze its components by using an analytical instrument, to know the result, and control the operation using the analysis result. A molten metal sampling probe is used to collect the metal sample, and one of the conventional examples is shown in FIGS. 3 and 4.

に形成された流入孔には蓋５がかぶせられている。FIG. 3 is a perspective view showing the outline of the appearance of a conventional molten metal sampling probe (hereinafter, simply referred to as a probe). The probe 1 is provided with an upper protection tube 2 and a lower protection tube 3 both made of paper, and the lower end of the lower protection tube 3 is sealed with a blind cap 4. A sample collection mold is housed near the inner lower end of the lower protection tube 3, and a lid 5 is put on the inflow hole formed in the lower protection tube so as to communicate with the mold.

９は一般的には石英管又はセラミック製の管である。FIG. 4 is a sectional view of the sampling portion of the probe of FIG. Near the inner lower end of the lower protection tube 3, a split-type sampling mold 6 is received with its inflow hole 7 aligned with the hole 8 of the lower protection tube 3. A recess 11 is formed around the hole 8 on the outer circumference of the lower protection tube 3. The inflow pipe 9 to the sampling die 6 is hermetically inserted into the hole 8 of the lower protection pipe 3,
The outer end thereof is flush with the bottom surface of the recess 11, and the inner end side is hermetically inserted into the inflow hole 7 of the sampling die 6. The inflow pipe 9 is generally a quartz pipe or a ceramic pipe.
凹所11には金属製の内蓋12が載置され、流入管９の外端

An outer lid 13 made of paper is directly placed on the inner lid 12 made of metal. These lids 12 and 13 prevent mixing of slag existing on the surface of the molten metal when the probe 1 is immersed in the molten metal, and are burned or melted by the molten metal in the molten metal to melt. The metal is allowed to flow into the sampling die 6.

問題が生ずる。(Problems to be Solved by the Invention) In the probe 1 configured as described above, the probe 1
When the probe 1 is pulled up from the molten metal, the molten metal 14 before solidification continuously flows out from the inside of the inflow pipe 9 along the bottom surface 11a of the recess 11 and solidifies in this state.
So-called drooling 16 occurs. FIG. 6 shows the sample 15 thus obtained. Hot water like this
The resulting sample 15 of 16 cannot be pneumatically transported to the analysis chamber using a paper cylinder, and cannot be chucked to an analytical instrument.
また、紙製の外蓋13が金属製の内蓋12に直接重ねて配置
してあるので、両方の蓋がほぼ同時に焼失あるいは溶融

混入し、いわゆるカーボンのピックアップが生じて試料
中の炭素の成分比が高くなり、溶融金属中の炭素の正し
い定量分析が行えないという問題も生ずる。Further, since the paper outer lid 13 is placed directly on the metal inner lid 12, both lids are burnt or melted almost at the same time, and the carbon generated from the paper outer lid 13 is the molten metal sample. There is also a problem that the carbon content in the sample becomes high and the component ratio of carbon in the sample becomes high, so that correct quantitative analysis of carbon in the molten metal cannot be performed.

凹所22が形成されている。The configuration of the present embodiment includes an upper protection tube (not shown), a lower protection tube 3, a sampling die 6, an inflow tube 9, an inner lid 23, an outer lid 24, etc., as in the conventional example described above. It is composed of.
A relatively deep recess is formed around the hole 8 of the lower protection tube 3.
21 is formed, and a relatively shallow recess 22 is formed around the recess 21.

It is located inward of the outer peripheral surface. An inner lid 23 made of metal is attached by directly covering the other end, while an outer lid 24 is arranged in the shallow recess 22 and is clearly shown in the figure between the inner lid 23 and the outer lid 24. A gap is provided.

うに湯だれのない良好な試料が得られる。(Effect of the Invention) Since the present invention is configured as described above, when the probe is pulled up from inside the molten metal, the molten metal flowing out from the inflow pipe 9 has a wall that is transmitted and flows as in the conventional example. Since it does not exist, it becomes a drop and drops from the end of the inflow tube, so-called boiling point is improved, and a good sample without dripping can be obtained as shown in FIG.

素量の定量分析が行える。Further, in the present invention, since a gap is provided between the inner lid and the outer lid, there is a time lag between the burnout of the paper outer lid and the melting of the metal inner lid. Therefore, since the inner lid is melted after the outer lid is completely burned, the carbon generated by the burning of the paper outer lid is not mixed in the sample, and the accurate quantitative analysis of the carbon amount can be performed.
