本発明は、出湯取鍋中の溶湯を注湯取鍋に移し替える際
に、溶湯中のスラグを除去するための溶湯注入器に関す
る。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a molten metal injector for removing slag from molten metal when transferring molten metal in a tapping ladle to a pouring ladle.
（従来の技術とその問題点）
従来、鋳型に溶湯を注湯するには、溶解炉や保持炉中の
溶湯をまず大形の出湯取鍋に移し替えた後、鋳型への注
湯量に応じて適宜の容量とされた注湯取鍋へ出湯取鍋中
の溶湯を分配し、これを鋳型に注入していた。(Conventional technology and its problems) Conventionally, in order to pour molten metal into a mold, the molten metal in the melting furnace or holding furnace was first transferred to a large tapping ladle, and then the amount of molten metal poured into the mold was adjusted according to the amount. The molten metal in the tapping ladle was distributed to a pouring ladle with an appropriate capacity, and then poured into the mold.
この際、溶湯中のスラグは注湯取鍋において除去される
のが通例である。これは、出湯取鍋においては、溶湯表
面に浮遊しているスラグにある程度保温効果を持たせて
いるからである。At this time, slag in the molten metal is usually removed in a pouring ladle. This is because in the tapping ladle, the slag floating on the surface of the molten metal has a certain degree of heat retention effect.
注湯取鍋におけるスラグの除去は、溶湯表面のスラグを
作業者がかき取っているのが実情である。In reality, slag removal in a pouring ladle involves a worker scraping off the slag on the surface of the molten metal.
このため、スラグの除去が不充分となっており、また作
業者には危険が伴ない、厳しい労働を強いることになっ
ている。For this reason, slag removal is insufficient, and workers are forced to work in a dangerous and difficult manner.
本発明はかかる問題点に鑑みなされたもので、作業者に
負担を強いることなく、注湯取鍋の熔へ１のスラグ除去
が容易に行える手段を提供することを１］的とする。The present invention has been made in view of such problems, and an object of the present invention is to provide a means for easily removing slag from the melt in a pouring ladle without imposing a burden on the worker.

自在に備えられている点にある。(Means for Solving the Problems) In order to achieve the purpose of tilting, a molten metal injector is provided that can remove slag in the molten metal when pouring the molten metal into a pouring ladle. The features of this molten metal injector are:
The inner surface of the syringe main body 7 is made of a refractory material, and a socket 8 is provided at the top of the main body 7, and the molten metal supplied from the socket 8 into the syringe main body 7 is discharged while remaining inside the main body 7. A discharge channel 9 is provided at the bottom of the injector main body 7, and a mesh filter 16 for filtrating the molten metal is detachably provided in the discharge channel 9.
（作 用）
溶湯注入器に供給された溶湯は、注入器本体内部に滞留
しながら流下排出されるので、溶湯表面に浮遊している
スラグは、溶湯の排出に伴って注入器本体内壁に付着し
て、ある程度除去される。(Function) The molten metal supplied to the molten metal injector flows down and is discharged while remaining inside the molten metal injector body, so the slag floating on the surface of the molten metal adheres to the inner wall of the injector body as the molten metal is discharged. It is removed to some extent.
また、排出流路に流入した溶湯は、該流路を流下する間
に網状フィル′多−によって濾過され、その中のスラグ
は機械的に分離されると共に吸着除去される。Further, the molten metal flowing into the discharge channel is filtered by a mesh filter while flowing down the channel, and the slag therein is mechanically separated and removed by adsorption.
樹状フィルターは排出流路に着脱自在に備えられている
から交換が容易である。Since the dendritic filter is removably provided in the discharge channel, it is easy to replace.
（実施例） 以下、本発明の実施例を第１図を参照して説明する。(Example) Embodiments of the present invention will be described below with reference to FIG.
実施例に係る注湯取鍋用溶湯注入器ｌは、架台２に設置
されており、該溶湯注入器１の下方に注湯取鍋３が載置
されている。４は出湯取鍋である。A molten metal pouring ladle injector 1 according to the embodiment is installed on a pedestal 2, and a molten metal pouring ladle 3 is placed below the molten metal injector 1. 4 is a hot water ladle.
前記溶湯注入器１は、概略漏斗状であり、内面が耐火材
層６で形成された注入器本体７を備え、その上部に受口
８が開設され、下部に排出流路９が開設されている。The molten metal injector 1 is roughly funnel-shaped and includes an injector main body 7 whose inner surface is formed of a refractory material layer 6, a socket 8 is provided in the upper part of the injector body 7, and a discharge channel 9 is provided in the lower part. There is.
前記受口８は、大容量の出湯取鍋４の傾動により、取鍋
から流出した金属溶湯を注入器本体７内部に受は入れる
ため、大口径とされている。The socket 8 has a large diameter in order to receive the molten metal flowing out from the ladle into the injector main body 7 due to the tilting of the large-capacity tapping ladle 4.

クランプである。もっとも、着脱自在に接続する手段と
して、クランプに限らず、ボルト・ナンドでもよくその
手段は自由である。The discharge channel 9 is connected to the socket 8 so that the molten metal flowing into the injector body 7 flows down while staying in the body 7.
It has a smaller diameter than the syringe body 7, and is opened in a discharge pipe section 11 extending below the syringe main body 7. The discharge pipe section 11 is
A base 12 integrally formed with the syringe main body 7, a middle tube portion 13 detachably connected to the base 12, and a middle tube portion 1.
3 and a lower pipe part 14 detachably connected to the lower pipe part 3. 15 is a clamp for removably connecting each part with a flange. However, the means for removably connecting is not limited to clamps, but may also be bolts or nands.
基部１２と中管部１３並びに中管部１３と下管部１４と
の間には網状フィルター１６が挟持されており、各部の
着脱により取付は取外し自由とされている。A mesh filter 16 is sandwiched between the base portion 12 and the middle tube portion 13, as well as between the middle tube portion 13 and the lower tube portion 14, and can be freely attached and removed by attaching and detaching each part.
尚、図示例では、フィルターを２枚設けたが、必要に応

欠陥の発生やフィルターの収縮による損傷を有効に防止
できるためである。The mesh filter 16 is made of fire-resistant fibers such as glass fibers and carbon fibers. When using a high-melting metal molten metal such as cast iron or cast steel as the casting metal, it is preferable that the glass fiber has a SiO□ content of 75 or more heavy oil cylinders and has been pre-fired and shrunk. This condition was clarified by the inventor in Japanese Patent Application No. 60-235032, and is applicable to all types of molten cast iron (casting temperature 1200-1450°C) with a 5iOz content of 75% or more. In addition, using a pre-fired and shrunk product is because the casting sand at the filter attachment part is scraped off into the molten metal by the collection of the filter when the molten metal passes through, causing casting defects such as sand pits and shrinkage of the filter. This is because damage caused by this can be effectively prevented.
網状フィルター１６は、通常フェノールレジン等が塗布
されて保形性が付与されるが、本発明においては、耐火
繊維が織製された織布をそのまま使用することもできる
。The mesh filter 16 is usually coated with phenol resin or the like to impart shape retention, but in the present invention, a woven fabric woven with fire-resistant fibers can also be used as is.
網状フィルター１６の目開きサイズは、除去するノロ、
スラグ等の非金属介在物の大きさにもよるが、通常０．
４〜４ｉで充分である。The opening size of the mesh filter 16 is determined by the size of the slag to be removed,
Although it depends on the size of nonmetallic inclusions such as slag, it is usually 0.
4 to 4i is sufficient.

度付着して除去される。According to the above configuration, hot water flows from the hot water ladle 3 into the socket 8. Since the molten metal 8 flows down and is discharged while remaining inside the injector main body 7, the slag on the surface of the molten metal adheres to the inner wall of the injector main body 7 to some extent and is removed.

From the outlet of the IJI outlet channel 9, the molten metal is dropped and supplied to the pouring ladle 3 placed below. Therefore, slag removal work in the pouring ladle 3 becomes unnecessary.
