［産業上の利用分野］
この発明は、固液共存状態にある半溶融金属の鋳造方法
に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for casting semi-molten metal in a solid-liquid coexistence state.
［従来の技術］
一般に、鋳片又は鋳塊は、鋳型により周辺部から冷却さ
れるため、その中心部に粗大樹枝状晶からなる偏析を有
する。中心偏析は、機械的性質その他の特性が周辺健全
部より劣る。このため、金属溶湯を鋳造する場合には、
樹枝状晶の発達を可能な限り抑制し、鋳片全体に占める
等軸晶の割合い（以下、等軸品率という）を高める必要
がある。[Prior Art] Generally, a slab or an ingot is cooled from the periphery by a mold, and therefore has segregation consisting of coarse dendrites in its center. The central segregation has mechanical properties and other properties inferior to those of the surrounding healthy area. Therefore, when casting molten metal,
It is necessary to suppress the development of dendrites as much as possible and increase the proportion of equiaxed crystals in the entire slab (hereinafter referred to as equiaxed product ratio).
等軸品率を高める鋳造技術として、例えば、低温鋳造法
及び電磁撹拌法等が知られている。しかしながら、これ
らの技術を利用してもなお、完全溶融状態の溶湯を鋳造
した場合に、凝固時の温度降下が大きいこと、及び冷却
速度が制限されること等の理由から、全領域にて粗大樹
枝状晶が発達することを阻止することは困難である。For example, low-temperature casting, electromagnetic stirring, and the like are known as casting techniques for increasing the equiaxed product rate. However, even if these technologies are used, when casting completely molten metal, the temperature drop during solidification is large and the cooling rate is limited, resulting in roughness in all areas. It is difficult to prevent dendrites from developing.
近時、省エネルギ及び省資源を目的として、一つの工程
で溶融金属から一次製品をつくりだす半溶融加工プロセ
スが開発実用化されつつある。所謂、半溶融加工プロセ
スとは、微細な固相を有する半溶融状態の溶湯を用いて

いう。すなわち、溶湯を液相線及び固相線の間の温度域
に適宜調整し、凝固直前の固液共存状態で溶湯を鋳型に
鋳込み、直ちに凝固させる。このような半溶融加工プロ
セスを利用すれば、等軸品率が向上し、組織が均一かつ
微細化する。Recently, with the aim of saving energy and resources, a semi-molten processing process for producing a primary product from molten metal in one process has been developed and put into practical use. The so-called semi-molten processing process refers to a technology that uses a semi-molten molten metal having a fine solid phase to directly form a product to increase the equiaxed product ratio. That is, the temperature of the molten metal is appropriately adjusted to a temperature range between the liquidus line and the solidus line, and the molten metal is poured into a mold in a solid-liquid coexistence state immediately before solidification, and immediately solidified. If such a semi-melting processing process is used, the equiaxed product rate will be improved and the structure will be uniform and fine.
従来の半溶融金属の鋳造方法は、容器及び鋳型のヘッド
差を利用して、ノズルを介して溶湯を鋳型内に自然落下
させる。A conventional method for casting semi-molten metal uses a head difference between a container and a mold to allow the molten metal to fall naturally into the mold through a nozzle.
［発明が解決しようとする課題］
しかしながら、従来の半溶融金属の鋳造方法においては
、半溶融状態の溶湯は粘性が高いので、自然落下させる
だけでは所定の鋳造速度を得ることが困難になる。特に
、溶湯の固相率を高めると、その流動性が著しく低下す
るので、鋳片を連続鋳造することが困難になる。また、
鋳塊を複雑形状の鋳型を用いて鋳造する場合に、鋳型の
溶湯注入領域（キャビティ）の隅々まで溶湯が十分にい
きわたらなくなる。このため、正確な形状の鋳塊を得る
ことができない。更に、溶湯のノズル通流速度が遅いた
めに、ノズルが塞閉することがあるという不都合を生じ
る。[Problems to be Solved by the Invention] However, in the conventional semi-molten metal casting method, since the molten metal in the semi-molten state has a high viscosity, it is difficult to obtain a predetermined casting speed just by letting it fall naturally. In particular, when the solid fraction of the molten metal is increased, its fluidity is significantly reduced, making it difficult to continuously cast slabs. Also,
When casting an ingot using a mold with a complicated shape, the molten metal does not sufficiently reach every corner of the molten metal injection region (cavity) of the mold. For this reason, it is not possible to obtain an ingot with an accurate shape. Furthermore, since the flow rate of the molten metal through the nozzle is slow, there is a problem that the nozzle may become clogged.
この発明は、かかる事情に鑑みてなされたものであって

することを目的とする。This invention was made in view of the above circumstances, and it is possible to increase the casting speed of semi-molten molten metal, make the shape of the ingot etc. highly accurate, and prevent nozzle clogging. It is an object of the present invention to provide a method for casting semi-molten metal that can be cast.

ることを特徴とする。[Means for Solving the Problems] The method for casting semi-molten metal according to the present invention involves controlling the temperature of the molten metal in a container to bring it into a solid-liquid coexistence state, and casting the molten metal into a mold through a nozzle in the container while stirring. In the method for casting semi-molten metal, the molten metal passage of the nozzle and the molten metal injection area of the mold are made to communicate directly, and the molten metal injection area of the mold is cast under reduced pressure.

That is, completely molten molten steel 3a is contained in the ladle 2, and is supplied to the semi-molten metal manufacturing apparatus 10 via the air seal vibe 4 at a predetermined flow rate. Container 1 of semi-molten metal manufacturing equipment
6 is covered with a lid 12 so that the inside of the apparatus is shut off from the atmosphere. A gas supply pipe (not shown) is provided on the lid 12 to supply inert gas into the apparatus 10. The rotor 26 is inserted into the container 16 through the M12 insertion hole, and its lower end reaches the outlet of the nozzle 20. The upper end of the rotor 26 is connected to a rotating device (not shown) and a lifting device (not shown), so that when the rotor 26 rotates, the molten metal is stirred, and when the rotor 26 moves up and down, the nozzle 20 opens and closes. .

That is, the molten metal passage of the nozzle and the cavity 30 are airtightly communicated, so that the molten metal is directly cast from the nozzle 20 into the mold 6.

張力のほうが上回り、溶鋼が通路３４内に侵入しない。Molten steel 3a adjusted to a predetermined composition and a predetermined temperature is placed in a ladle 2 and transported to a casting facility. The air seal vibe 4 is inserted into the device 10, and argon gas at a predetermined pressure is supplied through the gas supply pipe to create an inert gas atmosphere inside the device. Next, the nozzle of the ladle 2 is opened and the completely molten steel 3a is supplied to the container 16 via the air seal vibe 4. At this time, the rotor 26 is lowered in advance, and the molten metal passage 2
Block 3. The molten metal radiates heat through the container 16 and its temperature decreases. This is heated by the heater 18 and its temperature is adjusted to an appropriate temperature range between the solidus line and the liquidus line. As a result, the solid phase is crystallized in the liquid phase at a predetermined ratio to form molten steel 3b in a semi-molten state. In this case, the solid phase ratio is 0.2
It is preferable to control between ~0.8, and in the case of steel, it is 0.
．． It is more preferable to set the solid phase ratio to 5 to 0.6. When the molten metal is held for a long time, the solid phase, especially the dendrites, grows and becomes coarser. At this time, the rotor 26 is rotated at a predetermined rotation speed N to stir the molten steel 3b. Stirring breaks up the dendrites and forms fine crystal grains. Meanwhile, the gas in the cavity 30 is evacuated by the vacuum pump 40 to a pressure of 1 torr.
Reduce the pressure to several torr. Next, the switch of the heater 22 is turned on to heat the nozzle 20, while the rotor 26
Rotate and lift upward to open the flow passage 23 of the nozzle. Since the pressure in the cavity 30 is reduced, molten steel is forcefully sucked into the cavity 30 through the flow path 23,
The molten steel spreads all the way to the tip region of the branch 32. At this time, since the exhaust passage 34 has a small diameter, the surface tension exceeds the suction force, and molten steel does not enter the passage 34.
溶鋼が鋳型に接触すると、凝固直前の半溶融状態にある
ので、樹枝状晶が粗大化する余裕を与えることなく、そ
の内部に至るまで直ちに凝固する。When the molten steel comes into contact with the mold, it is in a semi-molten state just before solidification, so it immediately solidifies all the way to the inside of the mold, without giving any room for the dendrites to become coarse.

A molten metal inlet of a nozzle 20 of a semi-molten metal manufacturing apparatus is inserted into a cavity 52 of a continuous casting mold 50. An exhaust passage 54 is formed in the upper side wall of the mold 50. This exhaust passage 54 is provided so as to be located above the scene.

に勢いよく流入する。Next, the rotor (not shown) is lifted to open the nozzle 20, and molten steel is injected from the semi-molten metal manufacturing apparatus 10 into the mold 50. At this time, since the pressure inside the mold is reduced, the molten steel is sucked into the mold and flows through the nozzle 20 into the cavity 52.
There is a strong flow into.
