一方■のピンサンプラーは迅速な冷却、試料調製が容易
であるが、内部の健全性に問題がある。On the other hand, the pin sampler (2) has quick cooling and easy sample preparation, but has problems with internal integrity.
溶鋼を迅速に分析するためには、試料が速やかに冷却出
来、分析装置にかける迄の試料調製が容易である必要が
ある。In order to quickly analyze molten steel, it is necessary that the sample can be cooled quickly and that it is easy to prepare the sample before applying it to an analyzer.

った。In the past, when there was little need for rapid analysis, only the internal soundness was considered important, and samplers ① and ③ were used most of the time. No sampler was found sufficient to supply samples for emission spectroscopic analysis.

分析用ピンサンプラーである。In the present invention, a slag stopper made of a low carbon steel pipe is inserted and joined to a paper tube, and a quartz tube mold with a molten steel inlet on the side inside the slag stopper is installed outside the paper tube for quick analysis of molten steel. It is a pin sampler for

ーである。Furthermore, it is a pin sampler for rapid analysis of molten steel, which is a quartz tube mold with a diameter of 8 holes or more, and the quartz tube mold is protected by an iron tube.
本発明者等は、第４図に示す従来のピンサンプラーは、
内部の健全性のみに問題がある点に着目し、従来装置の
基本的な差は試料の形状、特に太さの点にあると考え、
種々の太さを有するピン試料についてその内部健全性に
ついて予め調査した結果、第２表を得た。The present inventors believe that the conventional pin sampler shown in FIG.
Focusing on the fact that the problem lies only in internal integrity, we believe that the fundamental difference between conventional devices lies in the shape of the sample, especially its thickness.
As a result of preliminary investigation of the internal soundness of pin samples having various thicknesses, Table 2 was obtained.
第２表 太さの異なるビシ試料の内部
健全性の比較
本夫々１０本のピンサンプルを任意の４箇所で切断しピ
ンホールがあった場合を不良とした。Table 2: Comparison of internal soundness of pin samples with different thicknesses Each of the 10 pin samples was cut at four arbitrary locations, and those with pinholes were considered defective.
第２表に示す如く、径が太くなるにつれて不良率は低減
し１５胴φでは、従来の第２図及び第３図のサンプラー
と略々間等であることを確かめた。As shown in Table 2, as the diameter becomes thicker, the defective rate decreases, and it was confirmed that for the 15 cylinder φ, the defect rate was approximately between that of the conventional samplers shown in FIGS. 2 and 3.
以上の結果に基づいて 本発明はなされたものである。The present invention has been made based on the above results.
即ち後述する実施例の第１図に示す如く、本発明では石

試料の取出し並びに冷却が有利である。That is, as shown in FIG. 1 of the embodiment described later, in the present invention, a sample mold made of quartz was provided outside the paper tube, so the fourth
It is advantageous to take out and cool the sample from the inside of the paper tube, as in the conventional pinsano puller shown in the figure.
又ビシサノブルの太さは、前述の第２表より８ ｍｍφ
以上が不良率の点から必要である。従って本発明に用い
る石英管の内径は８〜２０ｍｍが好ましい。Also, the thickness of the bishisannoble is 8 mmφ from the above-mentioned table 2.
The above is necessary from the viewpoint of defect rate. Therefore, the inner diameter of the quartz tube used in the present invention is preferably 8 to 20 mm.
更に脱酸鋼を採取する場合はアルミニウム線を予め石英
管製鋳型内に挿入して置くことが好ましい。Furthermore, when extracting deoxidized steel, it is preferable to insert an aluminum wire into a quartz tube mold in advance.
石英管製鋳型は裸ののままでは、溶鋼採取時スラグに当
たり、破損するので分析に支障ない低炭素鋼等の鉄以外
の成分の少ないスラグストッパー管で保護する必要があ
る。If the quartz tube mold is left bare, it will hit the slag during sampling of the molten steel and break, so it must be protected with a slag stopper tube made of low-carbon steel or other material that contains few components other than iron, which does not interfere with analysis.
溶鋼を採取すると、スラグストッパーは溶欠されている
ので溶鋼流入口の所で容易に破断出来るので、取出し、
冷却は極めて容易であり、又径が細いので迅速に切断し
、良好な分析面を得ることが出来る。When collecting molten steel, the slag stopper is notched and can easily break at the molten steel inlet, so take it out and
Cooling is extremely easy, and since the diameter is small, it can be cut quickly and a good analysis surface can be obtained.
