本発明は、製鋼炉から溶融金属を採取して、その分析用
試料を調製する溶融金属試料採取器に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a molten metal sampler for collecting molten metal from a steelmaking furnace and preparing samples for analysis thereof.
一般に、溶融金属試料採取器によって製鋼炉から採取さ
れた分析用試料は、冷却、凝固した後に、採取現場から
試料分析場まで輸送管を介して相当の距離にわたって圧
縮空気等によって圧送される。Generally, a sample for analysis is collected from a steelmaking furnace by a molten metal sampler, and after being cooled and solidified, it is pumped by compressed air or the like over a considerable distance from the collection site to a sample analysis site via a transport pipe.
従って、分析用試料は、搬送に適した形状を有している
ことが望ましい。Therefore, it is desirable that the sample for analysis has a shape suitable for transportation.
然るに従来の溶融金属試料採取器によって採取された分
析用試料は゛、その採取器内のサンプル・ケースの構造

、それ数分析用試料を輸送管内で確実に搬送するには、
鋳ダレ又は鋳バリを除（必要があった。そして、このよ
うな作業は費用がかかり、時間を浪費するものであるこ
とは明らかである。However, due to the structure of the sample case in the sampler, the analytical sample collected by a conventional molten metal sampler cannot be used, for example, in an inlet casting sump as shown in Fig. 1(a). , horizontal casting burrs shown in Figure 1 (, 5), and vertical casting burrs as shown in Figure 1 (c) are formed, and the sample for analysis is transported reliably in the transport pipe. for,
It was necessary to remove sag or flash, and it is clear that such an operation is expensive and time consuming.
従って、不発明は、第１図（ｄ）に示されたような健全
な、即ち、輸送管による搬送に逼した形状を有する分析
用試料を得ることができる改良された溶融金属試料採取
器を提供することを目的としている。Therefore, the present invention provides an improved molten metal sampler capable of obtaining a sample for analysis having a sound shape, that is, a shape suitable for transportation by a transport pipe, as shown in FIG. 1(d). is intended to provide.
本発明を図示実施例に従って以下に説明する。The invention will be described below with reference to illustrated embodiments.
第２図は、本発明の試料採取器の実施例を、断面図によ

室３との組合せ部４は、印ろう式嵌合部となっている。A sample case is housed in a protective tube 1 such as a paper tube or a refractory tube. It consists of a bottom chamber 3. The combination portion 4 of the upper chamber 2 and the bottom chamber 3 is a dowel type fitting portion.
保護管１及び上室２には、製鋼炉内で溶融金属を試料と

る。更に保護材７は、保護管１及び上室２の流入口を整
合させ、溶融金属の円滑な流入、流出に寄与している。The protection tube 1 and the upper chamber 2 are provided with an inlet 5 for obtaining molten metal as a sample in the steelmaking furnace, and below this inlet,
A taper at an angle θ is provided downward in the radial direction so that excess molten metal in the sample case flows down after sample collection. A protective material 7 made of mortar, for example, is provided in the protective tube portion of the inlet 5 to prevent deterioration of the protective tube 1 when molten metal flows in, and to prevent molten metal from forming between the protective tube 1 and the bottom chamber 3. Prevents metal from entering. Furthermore, the protective material 7 aligns the inlets of the protective tube 1 and the upper chamber 2, contributing to smooth inflow and outflow of molten metal.
従って、本発明の試料採取器を溶融金属中に浸漬した後
に引き上げると、サンプル・ケース内に金属試料６を採

ような縦鋳バリが発生する余地は全くない。Therefore, when the sample collector of the present invention is immersed in molten metal and then pulled up, at the same time as the metal sample 6 is collected in the sample case, the excess molten metal is transmitted through a portion of the taper as described above, and all of the metal sample 6 is removed from the outside. Therefore, the occurrence of casting sag at the inlet can be completely eliminated. Furthermore, due to the groove structure of the sample case equipped with the dowel-type fitting portion of the present invention, horizontal casting burrs as shown in FIG. , there is no room for vertical casting burrs to occur as shown in FIG. 1(c).

必要もない。In addition, in the present invention, if the pressure of the ferrule type fitting part 4 between the upper chamber 2 and the bottom chamber 3 is insufficient at the time of sample collection, capillary action will cause the metal sample to be exposed to the outermost periphery. There is a risk of vertical burrs forming parallel to the central axis of the sampler. However, since the formation of such casting flash coincides with the direction in which the analytical sample piece is pumped within the transport pipe, it is clear that it does not pose any problem during transport, and therefore there is no need to remove it.
