従来、金属溶融炉から溶融金属を採取し円筒形又は円板形の分析用試料を作る ため操作用のホルダー等に連結され使用される溶融金属試料採取器は、種々知ら れている。図６は、従来の溶融金属試料採取器を使用して採取され、固化され、 試料採取器から取り出されたほぼ円筒形の試料４の斜視図である。図６の従来の 試料４は、首部４２に結合した鋳ばり４３が円筒形試料本体４１の周面を越えて 突出しており、このような鋳ばり４３は、気送管による試料の移送や分析機器に よる試料の把持の妨げになる短所を有する。 2. Description of the Related Art Conventionally, there have been known various types of molten metal samplers which are connected to an operation holder or the like and used for sampling a molten metal from a metal melting furnace to produce a cylindrical or disk-shaped analysis sample. FIG. 6 is a perspective view of a generally cylindrical sample 4 taken, solidified, and removed from a conventional molten metal sampler. In the conventional sample 4 shown in FIG. 6, a flash 43 connected to the neck 42 protrudes beyond the peripheral surface of the cylindrical sample main body 41. Such a flash 43 is used for transferring and analyzing a sample by a pneumatic tube. It has disadvantages that hinder the sample from being gripped by the instrument.
【０００３】 実公平６−４３６７８号公報は、溶融金属試料採取用プローブを開示する。こ のプローブに組込まれた溶融金属試料採取器は、試料室と流入室の間に無機材料 の仕切りを備え、仕切り壁の中央を貫通する石英管により試料室と流入室が連通 され、石英管の上端部を流入室の流入口低部より高くすることにより、試料本体 の周面を越えて突出する鋳ばりの生成を防止する。しかしながら、この公報の溶 融金属試料採取器は、流入室が石英管を備える等、構造が複雑で部品点数も多い ため、材料費が比較的高価となり、製造工数も多い短所を有する。Japanese Utility Model Publication No. 6-43678 discloses a probe for sampling a molten metal. The molten metal sampler incorporated in this probe has a partition made of an inorganic material between the sample chamber and the inflow chamber, and the sample chamber and the inflow chamber are communicated by a quartz tube penetrating the center of the partition wall. By setting the upper end of the sample to be higher than the lower part of the inlet of the inflow chamber, it is possible to prevent the formation of a flash projecting beyond the peripheral surface of the sample body. However, the molten metal sampler disclosed in this publication has disadvantages in that the material cost is relatively expensive and the number of manufacturing steps is large because the structure is complicated and the number of parts is large, for example, the inflow chamber is provided with a quartz tube.

本考案の目的は、従来の溶融金属試料採取器の短所を改良することにあり、溶 融金属の流路を備える湯口部材及び試料室を備える金属製試料ケースから成る溶 融金属試料採取器において、湯口部材の形状構造を試料に大きな鋳ばりが生じな いものとすることにより、鋳ばりの切除を行うことなく気送管による試料の移送 を可能とし、分析機器において試料の把持に障害を生じることを無くすることで ある。本考案の他の目的は、溶融金属試料採取器において、割型から成る比較的 簡単な金型により一体の湯口部材を製造することにより、溶融金属試料採取器の 部品点数を最少とし、製造工数及び製造費用を少なくすることである。 An object of the present invention is to improve the disadvantages of the conventional molten metal sampler, and to provide a molten metal sampler comprising a sprue member having a flow path for molten metal and a metal sample case having a sample chamber. In addition, by making the shape and structure of the sprue member such that large burrs do not occur in the sample, it is possible to transfer the sample by a pneumatic tube without cutting off the burrs and obstruct the gripping of the sample in the analytical instrument. It is to eliminate it. Another object of the present invention is to minimize the number of parts of the molten metal sampler by manufacturing an integrated gate member with a relatively simple mold made of a split mold in the molten metal sampler. And to reduce manufacturing costs.
【０００５】 本考案の別の目的は、湯口部材の形状構造及び寸法を適切に選定することによ り試料採取器が溶融金属に浸漬されたとき溶融金属が小さな流動抵抗により試料 室内へ急速に流入充填され、溶融金属中から引き上げられたとき流入室の余分の 溶融金属が凝固することなく流出して鋳ばりの小さい均質の分析用試料を得るこ とができる溶融金属試料採取器を提供することである。本考案のその他の目的及 び利点は、以下の記載において明らかにされる。Another object of the present invention is to properly select the shape and structure of the sprue member so that when the sampler is immersed in the molten metal, the molten metal rapidly enters the sample chamber due to small flow resistance. Provided is a molten metal sampler which is capable of obtaining a homogeneous analysis sample with small burrs by flowing in without being solidified when excess molten metal in the inflow chamber is solidified when the molten metal is filled in and drawn out of the molten metal. That is. Other objects and advantages of the present invention will be clarified in the following description.
【０００６】[0006]
本考案の溶融金属試料採取器は、円筒形の試料室を備える金属製試料ケース及 び耐火材料製の湯口部材を含み、試料ケース及び湯口部材の外形は、略同一直径 の円筒形であり、湯口部材の下面が試料室の上部を閉鎖するように試料ケースの 上面に係合される。湯口部材は、略漏斗状の流入室及び略円筒形の流路を備え、 流路は、湯口部材の軸線方向に伸長し、一端において試料室に連通すると共に他 端において流入室の小径部に連通し、略漏斗状の流入室は、湯口部材の外周面付 近に大径部を備え、湯口部材中心部に小径部を備える。流入室の大径部の直径Ａ は、小径部の直径Ｂの少なくとも１．２５倍である。 The molten metal sampler of the present invention includes a metal sample case having a cylindrical sample chamber and a sprue member made of a refractory material, and the outer shapes of the sample case and the sprue member are cylindrical with substantially the same diameter. The lower surface of the gate member is engaged with the upper surface of the sample case so as to close the upper portion of the sample chamber. The sprue member has a substantially funnel-shaped inflow chamber and a substantially cylindrical flow path. The flow path extends in the axial direction of the sprue member and communicates with the sample chamber at one end and a small-diameter portion of the inflow chamber at the other end. The communicating, substantially funnel-shaped inflow chamber has a large-diameter portion near the outer peripheral surface of the sprue member and a small-diameter portion at the center of the sprue member. The diameter A 1 of the large diameter portion of the inflow chamber is at least 1.25 times the diameter B of the small diameter portion.
【０００７】 本考案の溶融金属試料採取器は、次の構成を備えることができる。（１）湯口 部材は、一体に成形されたシェルモールド成形物である。（２）流路の軸線と流 入室の軸線が略垂直に交差する。（３）流入室の大径部の直径Ａ、流入室の小径 部の直径Ｂ及び流路の直径Ｃは、Ａ＞Ｂ＞Ｃの関係を有する。（４）流入室の大 径部の直径Ａは、２５〜３５ｍｍである。（５）流入室の小径部の直径Ｂは、１ ６〜２０ｍｍである。（６）流路の直径Ｃは、８〜２０ｍｍである。（７）試料 室と流路が同軸に形成される。[0007] The molten metal sampler of the present invention can have the following configuration.

(6) The diameter C of the channel is 8 to 20 mm. (7) The sample chamber and the channel are formed coaxially.
【０００８】[0008]
本考案において、試料採取器が、操作用ホルダーに連結されて溶融金属中へ浸 漬されると、溶融金属は、流入室の漏斗状の内壁面に案内され、流路を経て試料 室内へ小さな流動抵抗により円滑に流入し、試料室を急速に充填する。試料室内 の空気の一部分は、流入する溶融金属と入れ替わりに流路から排出され、試料室 内の残りの空気は、湯口部材の下面と試料ケースの上面の間の隙間を通り又は湯 口部材中の微小孔を通り試料室内から排出される。 In the present invention, when the sampler is connected to the operation holder and immersed in the molten metal, the molten metal is guided to the funnel-shaped inner wall surface of the inflow chamber, and enters the sample chamber through the flow path. It flows in smoothly due to flow resistance and fills the sample chamber rapidly. A part of the air in the sample chamber is discharged from the flow path in place of the inflowing molten metal, and the remaining air in the sample chamber passes through a gap between the lower surface of the sprue member and the upper surface of the sample case or in the sprue member. Is discharged from the sample chamber through the micropores.
【０００９】 試料室に溶融金属が充填された後、直ぐに試料採取器が溶融金属中から引上げ られる。流入室の大径部が溶融金属表面から上昇されるとき、流入室の溶融金属 が流入室の漏斗状壁面に案内され流入室から円滑に排出される。流路上方の固化 し始めた溶融金属に結合して流入室に残留する溶融金属の量は、少量となる。試 料室に充填された溶融金属は、試料ケースにより熱を奪われ、固化する。試料採 取器内の固化した試料は、湯口部材を除去し試料ケースから取出され、分析用試 料とされる。[0009] Immediately after the sample chamber is filled with molten metal, the sampler is withdrawn from the molten metal. When the large diameter portion of the inflow chamber is raised from the surface of the molten metal, the molten metal in the inflow chamber is guided by the funnel-shaped wall of the inflow chamber, and is smoothly discharged from the inflow chamber. The amount of the molten metal remaining in the inflow chamber by being combined with the solidified molten metal above the flow path is small. The molten metal filled in the sample chamber is deprived of heat by the sample case and solidified. The solidified sample in the sample collector is removed from the sample case after removing the sprue member and used as an analysis sample.

The diameter A of the large diameter portion 51 of the inflow chamber is 25 to 35 mm, the diameter B of the small diameter portion 52 of the inflow chamber 5 is 16 to 20 mm, and the diameter C of the flow path 54 is 8 to 20 mm.

The sprue member 21 is formed by filling and hardening the shell mold material into a mold including two split molds having a semi-cylindrical surface and a split mold corresponding to the bottom surface of the sprue member, and then disassembling and removing the split mold. . The inflow chamber 5 formed in one of the two split molds having a semi-cylindrical surface and a protruding portion corresponding to a connection portion between the inflow chamber and the flow path 54 are formed by moving the split mold along the axis of the inflow chamber from the gate member.

FIG. 5 is a cross-sectional view similar to FIG. 1 showing a state of a sample 4, and FIG. 5 is a perspective view showing a sample collected by the sample collector of FIGS. is there. As shown in FIG. 4, the molten metal in the inflow chamber 5 is guided by the wall surface expanding outward of the inflow chamber 5 when the inflow chamber is filled with the molten metal and then pulled up from the molten metal. Due to the low flow resistance, the molten metal flows out of the inflow chamber 5 without being solidified in a short period of time. The amount is small. When the molten metal is filled into the sample chamber 12 through the flow path 54, the air in the sample chamber 12 is discharged through the flow path 54 or between the lower surface 24 of the gate member 21 and the upper surface of the sample case 11. The sample is discharged from the sample chamber 12 through the gap or the small hole in the gate member.
【００１５】 図５は、図４の溶融金属が固化した試料４を試料採取器１０から取出して示す ものであり、試料の首部４２に付着する鋳ばり４３の寸法は、極めて小さく、試 料本体４１の外周面を越えて突出しない状態にある。図５の試料４は、鋳ばり４ ３の切断作業なしに気送管を用いて移送することが可能であり、またその鋳ばり は分析機器において試料の把持の妨げにならない。それ故、迅速で且つ安価に溶 融金属の分析用試料を作ることができる。FIG. 5 shows the sample 4 from FIG. 4 in which the molten metal has been solidified, taken out of the sample collector 10. The size of the flash 43 attached to the neck 42 of the sample is extremely small, and 41 does not protrude beyond the outer peripheral surface. The sample 4 in FIG. 5 can be transported using a pneumatic tube without cutting the flash 43, and the flash does not hinder the gripping of the sample in the analytical instrument. Therefore, a sample for the analysis of a molten metal can be made quickly and at low cost.

本考案の溶融金属試料採取器において、溶融金属試料採取器が、操作用ホルダ ーに連結されて溶融金属中へ浸漬されると、封鎖部材１６が焼失され、溶融金属 は、流入室の漏斗状の内面に案内され、流路５４を経て試料室１２内へ小さな流 動抵抗により円滑に流入し、試料室を急速に充填する。試料室内の空気は、流路 又は試料ケースと湯口部材の間の隙間若しくは湯口部材中の微笑孔を通り排出さ れる。試料室に溶融金属が充填された後、直ぐに試料採取器が溶融金属中から引 上げられる。流入室の大径部が溶融金属表面から上昇されるとき、流入室の溶融 金属が漏斗形状に案内され流入室から円滑に排出され、流路上方の固化し始めた 溶融金属に結合して流入室に残留し鋳ばりとなる溶融金属の量は、少量となり、 試料の首部に付着する鋳ばりの寸法は、小さくなる。 In the molten metal sampler of the present invention, when the molten metal sampler is connected to the operation holder and immersed in the molten metal, the sealing member 16 is burned out, and the molten metal is formed in a funnel shape in the inflow chamber. And smoothly flows into the sample chamber 12 through the flow path 54 into the sample chamber 12 with a small flow resistance, thereby rapidly filling the sample chamber. The air in the sample chamber is discharged through a flow path, a gap between the sample case and the gate member, or a smiling hole in the gate member. Immediately after the sample chamber is filled with molten metal, the sampler is pulled out of the molten metal. When the large diameter part of the inflow chamber is raised from the surface of the molten metal, the molten metal in the inflow chamber is guided in a funnel shape, smoothly discharged from the inflow chamber, and combined with the molten metal that has begun to solidify above the flow path and flows in. The amount of molten metal remaining in the chamber and forming a flash becomes smaller, and the size of the flash attached to the neck of the sample becomes smaller.
【００１７】 大径部の直径Ａが小径部の直径Ｂの少なくとも１．２５倍である漏斗状の流入 室は、溶融金属の流入及び余分な溶融金属の流出を円滑にすると共に、湯口部材 の形成工程用の金型を割型だけで形成可能とする。また、湯口部材とほぼ同軸に 伸長する円筒形流路は、溶融金属を試料室へその中心から全方角へ均等に流入さ せ試料を均一のものとすると共に、湯口部材の形成において流路に対応する金型 を簡単なものとする。湯口部材を製造する金型は、流路の軸線と流入室の軸線が 略垂直に交差することにより、割型から成る取外し容易な比較的単純な構造とす ることができる。The funnel-shaped inflow chamber in which the diameter A of the large-diameter portion is at least 1.25 times the diameter B of the small-diameter portion facilitates the inflow of the molten metal and the outflow of the excess molten metal, and at the same time, allows the A mold for a forming step can be formed only by a split mold. The cylindrical flow path, which extends almost coaxially with the gate member, allows the molten metal to flow uniformly into the sample chamber from the center in all directions to make the sample uniform and to form a flow path in the formation of the gate member. The corresponding mold should be simple. The mold for manufacturing the sprue member can have a relatively simple structure composed of a split mold, which is easy to remove, because the axis of the flow path and the axis of the inflow chamber intersect substantially vertically.
