1 shows a cross-sectional view along AA in FIG.
A larger diameter paper tube 2 is connected to the lower end portion of
A sample collection container 3 is fixed to the paper tube 2. The sampling container 3 is made of a metal container having a thickness of two, and collects, for example, a so-called coin-shaped sample having an outer diameter of about 25 to 400 mm and a thickness of 10 to 25 mm. It is connected. The sampling tube 4 is formed of a quartz tube, and its tip is covered with an iron cap 5.

鎮静するためのアルミニウム線８が内挿されている。In order to measure the carbon content in the molten steel, a single glass tube 6 containing a platinum / platinum rhodium thermocouple made of a fine wire is inserted into the sample collection container 3 from above. The thermocouple is connected to a connection unit 7 provided above the sampling container 3 via a compensating lead wire (not shown). Further, an aluminum wire 8 for calming the sampled molten steel is inserted in the sample collection container 3.

In addition, 11 is an air vent hole of the sampling container 3, and 12 is a paper cylinder for fixing the sampling container 3.

込むように浸漬する。In order to carry out sampling and measurement of the carbon content using this apparatus, a pipe-shaped holder having a connector for electrically connecting to the connection unit 7 at the tip is mounted in the probe paper tube 1. Then, the lead wire passed through the holder is connected to the connection unit 7 to form a circuit for temperature measurement. Then, the paper tube 2 is immersed in the molten steel while supporting the holder.

試料採取の妨げにはならない。The cap 10 is broken while the tip of the paper tube 1 breaks through the steel slag layer, and when the paper tube 1 reaches molten steel, the cap 5 is melted. The molten steel is introduced, and the molten steel is calmed down by the aluminum wire 8 to obtain a molten steel sample with less segregation. With the introduction of the molten steel, the air in the sample collection container 3 is pushed out from the air vent hole 11, but the air corresponding to the pressure increase in the surrounding space escapes into the probe paper tube 1,
Does not interfere with sampling.

のまま分析を行うことが可能である。When the holder is lifted, a target molten steel sample is collected in the sample collection container 3. If the holder is left as it is for a short time, a cooling temperature curve is obtained by the thermocouple in the sample collection container 3. The solidification temperature of the molten steel can be measured on the basis of the above, and by converting this temperature into a carbon content using a table, the carbon content in the molten steel can be measured. Thereafter, the sample that has broken the paper tube 2 and solidified is taken out of the sample collection container 3 and sent to an instrumental analyzer for component analysis. The analysis surface of the sample obtained in the sample collection container 3 is flat and smooth by being in contact with the flat portion of the sample collection container 3,
The analysis can be performed as it is by the instrument analyzer with almost no need for sample preparation.
