本発明は鋳造用／８湯保持炉に関し、詳しくは脱ガス鎮
静化機能を備えた鋳造用溶湯保持炉に関する。DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a molten metal holding furnace for casting, and more particularly to a molten metal holding furnace for casting equipped with a degassing suppression function.
鋳造に用いる鋳鉄、アルミニウム等の溶湯には、酸素、

）をおこなっている。Molten metals such as cast iron and aluminum used for casting contain oxygen,
Contains gases such as nitrogen and hydrogen. These gases may be generated from the melted material during melting or f8'/
When transferring Jk, it will grow more each time you blow in air, etc. When casting is performed using a molten metal containing more than a certain amount of these gases, casting defects such as pin holes and gas holes are likely to occur. Therefore, in order to prevent such casting defects,
Usually, before casting, the molten metal is subjected to degassing treatment (degassing purification treatment).

することができるものである。This degassing suppression treatment is usually performed in a molten metal holding furnace before casting. This molten metal holding furnace receives a large amount of molten metal from the melting furnace, temporarily holds it, and can constantly dispense the molten metal in small quantities.

とがある。This degassing suppression treatment includes two methods: leaving the molten metal for a long time to spontaneously emit gas (the first conventional method), and adding a degassing accelerator such as chloride or inert gas to the molten metal. Method of blowing to promote degassing (second conventional method)
There is.

交互に使用するか、溶湯保持炉を大きくして鎮静化した
残湯量を増やし受湯する溶湯のガスを薄めて使用する必
要があり、設備が大量りになるという問題がある。Among these, the first conventional method takes time to suppress degassing and increases the cost of heat retention, and the original function of the molten metal holding furnace is to receive a large amount of molten metal from the melting furnace and constantly dispense it in small quantities. In order to meet this requirement, it is necessary to install two molten metal holding furnaces and use them alternately, or to increase the size of the molten metal holding furnace, increase the amount of residual molten metal, and dilute the gas of the receiving molten metal. There is a problem with the amount of equipment needed.
また、第２の従来法は、脱ガス促進剤の費用の他に、塩

要になり、歩留りが悪いという問題がある。In addition to the cost of the degassing promoter, the second conventional method also requires processing costs to compensate for the reduction in molten metal temperature, the generation of slag, and the removal of harmful gases by introducing or blowing in a salt gas promoter. There is a problem that it gets bulky. Furthermore, since the processing time is considerable, the operating efficiency of casting equipment that uses the molten metal discharged from the molten metal holding furnace is significantly reduced. In addition, the temperature of the mold, etc. into which the metal is poured drops, so it becomes necessary to cast the mold (cast without making it into a product) in order to raise the temperature of the mold, etc. when pouring the metal again, resulting in poor yield. There is.
〔発明の目的〕

る鋳造用溶湯保持炉によって達成される。According to the present invention, this purpose is to receive the molten metal from above,
This is a type of molten metal holding furnace for casting that preferentially taps the molten metal accumulated in the lower part, and the inside of this molten metal holding furnace has a cross-sectional area smaller than that of the /8 molten metal holding furnace, /8+& This is achieved by a molten metal holding furnace for casting characterized in that a partition plate that partitions the inside of the holding furnace into an upper and lower part is provided substantially horizontally.
なお、仕切板の周縁に、上方を曲りでフランジを設ける
ことが望ましい。Note that it is desirable to provide a flange on the periphery of the partition plate with a flange bent upward.

。Casting melt of the present invention/! According to the holding furnace A, the molten metal poured into the molten metal holding furnace containing a relatively large amount of gas is blocked by the partition plate, and most of it does not flow below the partition plate, but instead flows above the partition plate. accumulate. Therefore, the turbulence (stirring) of the molten metal caused by the receiving metal is not transmitted to the calmed molten metal that exists below the finishing J plate. Therefore, from the lower part of the molten metal holding furnace, the 4? M can be tapped.

態となる。The remaining metal below the partition plate is gradually reduced by tapping, and the molten metal above the partition plate is sequentially replenished downward through the gap formed by the inner wall of the molten metal holding furnace and the partition plate. At this time, the replenished molten metal initially has a high gas content, but due to the large amount of remaining metal, the amount of gas is diluted by the remaining metal, and as time passes, the gas naturally evaporates. By the time the bath is released, the gas has been sufficiently degassed and the condition has calmed down.
以上より、本発明の鋳造用溶湯保持炉によれば、以下の
