Description

本発明は引上式連続鋳造装置及び引上式連続鋳造方法に関する。   The present invention relates to an up-drawing continuous casting apparatus and an up-drawing continuous casting method.

特許文献１には、発明者らにより、鋳型を要しない画期的な引上式連続鋳造方法として、自由鋳造方法が提案されている。特許文献１に示したように、溶融金属（溶湯）の表面（すなわち湯面）にスタータを浸漬させた後、当該スタータを引き上げると、溶湯の表面膜や表面張力によりスタータに追従して溶湯も導出される。ここで、湯面近傍に設置された形状規定部材を介して、溶湯を導出し、冷却することにより、所望の断面形状を有する鋳物を連続鋳造することができる。   In Patent Document 1, the inventors have proposed a free casting method as an innovative pulling-up-type continuous casting method that does not require a mold. As shown in Patent Document 1, after the starter is immersed in the surface of the molten metal (molten metal) (that is, the molten metal surface), when the starter is pulled up, the molten metal follows the starter by the surface film or surface tension of the molten metal. Derived. Here, a casting having a desired cross-sectional shape can be continuously cast by deriving and cooling the molten metal through a shape determining member installed in the vicinity of the molten metal surface.

通常の連続鋳造方法では、鋳型によって断面形状とともに長手方向の形状も規定される。とりわけ、連続鋳造方法では、鋳型内を凝固した金属（すなわち鋳物）が通り抜ける必要があるため、鋳造された鋳物は長手方向に直線状に延びた形状となる。
これに対し、自由鋳造方法における形状規定部材は、鋳物の断面形状のみを規定し、長手方向の形状は規定しない。そして、形状規定部材は、湯面に平行な方向（すなわち水平方向）に移動可能であるから、長手方向の形状が様々な鋳物が得られる。例えば、特許文献１には、長手方向に直線状でなく、ジグザグ状あるいは螺旋状に形成された中空鋳物（すなわちパイプ）が開示されている。 In a normal continuous casting method, the shape in the longitudinal direction is defined along with the cross-sectional shape by the mold. In particular, in the continuous casting method, since the solidified metal (that is, the casting) needs to pass through the mold, the cast casting has a shape extending linearly in the longitudinal direction.
On the other hand, the shape defining member in the free casting method defines only the cross-sectional shape of the casting, and does not define the shape in the longitudinal direction. And since a shape prescription | regulation member can move to the direction (namely, horizontal direction) parallel to a molten metal surface, the casting in which the shape of a longitudinal direction is various is obtained. For example, Patent Document 1 discloses a hollow casting (that is, a pipe) that is formed in a zigzag shape or a spiral shape instead of being linear in the longitudinal direction.

以下、本発明を適用した具体的な実施の形態について、図面を参照しながら詳細に説明する。ただし、本発明が以下の実施の形態に限定される訳ではない。また、説明を明確にするため、以下の記載及び図面は、適宜、簡略化されている。   Hereinafter, specific embodiments to which the present invention is applied will be described in detail with reference to the drawings. However, the present invention is not limited to the following embodiment. In addition, for clarity of explanation, the following description and drawings are simplified as appropriate.

（実施の形態１）
まず、図１を参照して、実施の形態１に係る自由鋳造装置（引上式連続鋳造装置）について説明する。図１は、実施の形態１に係る自由鋳造装置の断面図である。図１に示すように、実施の形態１に係る自由鋳造装置は、溶湯保持炉１０１、３つの内部形状規定部材１０２ａ１、１０２ａ２、１０２ａ３、外部形状規定部材１０２ｂ、４本の内部冷却ガスノズル１０３、支持ロッド１０４、アクチュエータ１０５、外部冷却ガスノズル１０６を備えている。図１におけるｘｙ平面は水平面を構成し、ｚ軸方向が鉛直方向である。より具体的には、ｚ軸のプラス方向が鉛直上向きとなる。 (Embodiment 1)
First, with reference to FIG. 1, the free casting apparatus (pull-up type continuous casting apparatus) according to Embodiment 1 will be described. 1 is a cross-sectional view of a free casting apparatus according to Embodiment 1. FIG. As shown in FIG. 1, the free casting apparatus according to Embodiment 1 includes a molten metal holding furnace 101, three internal shape defining members 102a1, 102a2, 102a3, an external shape defining member 102b, four internal cooling gas nozzles 103, and a support. A rod 104, an actuator 105, and an external cooling gas nozzle 106 are provided. The xy plane in FIG. 1 constitutes a horizontal plane, and the z-axis direction is the vertical direction. More specifically, the positive direction of the z axis is vertically upward.

溶湯保持炉１０１は、例えばアルミニウムやその合金などの溶湯Ｍ１を収容し、所定の温度に保持する。図１の例では、鋳造中に溶湯保持炉１０１へ溶湯を補充しないため、鋳造の進行とともに溶湯Ｍ１の表面（つまり湯面）は低下する。他方、鋳造中に溶湯保持炉１０１へ溶湯を随時補充し、湯面を一定に保持するような構成としてもよい。なお、当然のことながら、溶湯Ｍ１は他のアルミニウム以外の金属や合金であってもよい。   The molten metal holding furnace 101 accommodates a molten metal M1 such as aluminum or an alloy thereof and holds it at a predetermined temperature. In the example of FIG. 1, since the molten metal is not replenished to the molten metal holding furnace 101 during casting, the surface of the molten metal M1 (that is, the molten metal surface) decreases as the casting progresses. On the other hand, the molten metal may be replenished to the molten metal holding furnace 101 at any time during casting to keep the molten metal surface constant. As a matter of course, the molten metal M1 may be another metal or alloy other than aluminum.

内部形状規定部材１０２ａ１、１０２ａ２、１０２ａ３及び外部形状規定部材１０２ｂは、例えばセラミックスやステンレスなどからなり、湯面近傍に配置されている。図１の例では、３つの内部形状規定部材１０２ａ１、１０２ａ２、１０２ａ３及び１つの外部形状規定部材１０２ｂが湯面に接触するように配置されている。しかしながら、内部形状規定部材１０２ａ１、１０２ａ２、１０２ａ３及び外部形状規定部材１０２ｂは、それらの下側（湯面側）の主面が湯面に接触しないように設置されてもよい。具体的には、内部形状規定部材１０２ａ１、１０２ａ２、１０２ａ３及び外部形状規定部材１０２ｂの下側の主面と湯面との間に所定の（例えば０．５ｍｍ程度の）ギャップを設けてもよい。
３つの内部形状規定部材１０２ａ１、１０２ａ２、１０２ａ３は、鋳造する鋳物Ｍ３の内部形状を規定し、外部形状規定部材１０２ｂは、鋳造する鋳物Ｍ３の外部形状を規定する。 The internal shape defining members 102a1, 102a2, 102a3 and the external shape defining member 102b are made of, for example, ceramics or stainless steel, and are disposed in the vicinity of the molten metal surface. In the example of FIG. 1, three internal shape defining members 102a1, 102a2, 102a3 and one external shape defining member 102b are arranged so as to contact the molten metal surface. However, the inner shape defining members 102a1, 102a2, 102a3 and the outer shape defining member 102b may be installed such that their main surfaces on the lower side (the hot water surface side) do not contact the hot water surface. Specifically, a predetermined gap (for example, about 0.5 mm) may be provided between the main surface of the inner shape defining members 102a1, 102a2, 102a3 and the outer shape defining member 102b and the molten metal surface.
The three internal shape defining members 102a1, 102a2, and 102a3 define the internal shape of the casting M3 to be cast, and the external shape defining member 102b defines the external shape of the cast M3 to be cast.

図１に示すように、溶湯Ｍ１は、その表面膜や表面張力により鋳物Ｍ３に追従して引き上げられ、溶湯通過部１０２ｃを通過する。ここで、溶湯の表面膜や表面張力によって、鋳物Ｍ３に追従して湯面から引き上げられた溶湯を保持溶湯Ｍ２と呼ぶ。また、鋳物Ｍ３と保持溶湯Ｍ２との界面が凝固界面である。   As shown in FIG. 1, the molten metal M1 is pulled up following the casting M3 by its surface film and surface tension, and passes through the molten metal passage portion 102c. Here, the molten metal pulled up from the molten metal surface following the casting M3 by the surface film or surface tension of the molten metal is referred to as a retained molten metal M2. Further, the interface between the casting M3 and the retained molten metal M2 is a solidification interface.

内部形状規定部材１０２ａ１、１０２ａ３の中央部には、それぞれ内部冷却ガスノズル１０３が接続されている。２つに分割される内部形状規定部材１０２ａ２は、それぞれの中央部に内部冷却ガスノズル１０３が接続されている。これら４本の内部冷却ガスノズル１０３は、それぞれの内部形状規定部材１０２ａ１、１０２ａ２、１０２ａ３の中央部から鋳物Ｍ３に向かって冷却ガス（空気、窒素、アルゴンなど）を吹き付け、鋳物Ｍ３を内部から冷却している。同時に、内部冷却ガスノズル１０３は、内部形状規定部材１０２ａ１、１０２ａ２、１０２ａ３を支持している。   Internal cooling gas nozzles 103 are connected to the central portions of the internal shape defining members 102a1 and 102a3, respectively. The internal shape defining member 102a2 divided into two has an internal cooling gas nozzle 103 connected to the center of each. These four internal cooling gas nozzles 103 spray cooling gas (air, nitrogen, argon, etc.) from the central part of each internal shape defining member 102a1, 102a2, 102a3 toward the casting M3 to cool the casting M3 from the inside. ing. At the same time, the internal cooling gas nozzle 103 supports the internal shape defining members 102a1, 102a2, and 102a3.

２本の支持ロッド１０４は、２つに分割される外部形状規定部材１０２ｂのそれぞれを支持している。内部冷却ガスノズル１０３、支持ロッド１０４により、内部形状規定部材１０２ａ１、１０２ａ２、１０２ａ３と外部形状規定部材１０２ｂとの位置関係を維持することができる。また、形状規定部材１０２の分割動作あるいは結合動作を行うことができる。   The two support rods 104 support each of the external shape defining members 102b divided into two. The internal cooling gas nozzle 103 and the support rod 104 can maintain the positional relationship between the internal shape defining members 102a1, 102a2, 102a3 and the external shape defining member 102b. Further, the dividing operation or the combining operation of the shape defining member 102 can be performed.

２つアクチュエータ１０５には、それぞれ２つの内部冷却ガスノズル１０３及び１つの支持ロッド１０４が連結されている。２つのアクチュエータ１０５は、同調して、内部冷却ガスノズル１０３及び支持ロッド１０４を上下方向（鉛直方向）及び水平方向に移動させることができる。そのため、鋳造の進行による湯面の低下とともに、内部形状規定部材１０２ａ１、１０２ａ２、１０２ａ３及び外部形状規定部材１０２ｂを下方向に移動させることができる。また、内部形状規定部材１０２ａ１、１０２ａ２、１０２ａ３及び外部形状規定部材１０２ｂを水平方向に移動させることができる。そのため、鋳物Ｍ３の長手方向の形状を自由に変化させたり、形状規定部材１０２の分割動作あるいは結合動作を行ったりすることができる。   Two actuators 105 are connected to two internal cooling gas nozzles 103 and one support rod 104, respectively. The two actuators 105 can move the internal cooling gas nozzle 103 and the support rod 104 in the vertical direction (vertical direction) and the horizontal direction in synchronization. For this reason, the inner shape determining members 102a1, 102a2, 102a3 and the outer shape determining member 102b can be moved downward as the molten metal surface decreases due to the progress of casting. Further, the inner shape defining members 102a1, 102a2, 102a3 and the outer shape defining member 102b can be moved in the horizontal direction. Therefore, the shape of the casting M3 in the longitudinal direction can be freely changed, and the shape defining member 102 can be divided or joined.

外部冷却ガスノズル（外部冷却部）１０６は、鋳物Ｍ３に冷却ガス（空気、窒素、アルゴンなど）を吹き付け、冷却するためのものである。スタータＳＴに連結された引上機（不図示）により鋳物Ｍ３を引き上げつつ、冷却ガスにより鋳物Ｍ３を冷却することにより、凝固界面近傍の保持溶湯Ｍ２が順次凝固し、鋳物Ｍ３が形成されていく。   The external cooling gas nozzle (external cooling part) 106 is for blowing and cooling cooling gas (air, nitrogen, argon, etc.) on the casting M3. While the casting M3 is pulled up by a pulling machine (not shown) connected to the starter ST and the casting M3 is cooled by the cooling gas, the retained molten metal M2 near the solidification interface is sequentially solidified to form the casting M3. .

次に、図２Ａ、２Ｂを参照して、形状規定部材１０２の詳細について説明する。図２Ａは、形状規定部材１０２の平面図（結合時）である。図２Ｂは、形状規定部材１０２の平面図（分割時）である。図２Ａ、２Ｂに示すように、形状規定部材１０２は、内部形状規定部材１０２ａ１、１０２ａ２、１０２ａ３及び外部形状規定部材１０２ｂを備えている。ここで、図１の内部形状規定部材１０２ａ１、１０２ａ２、１０２ａ３及び外部形状規定部材１０２ｂの断面図は、図２ＡのＩ−Ｉ断面図に相当する。なお、図２Ａ、２Ｂにおけるｘｙｚ座標は、図１と一致している。   Next, the details of the shape defining member 102 will be described with reference to FIGS. 2A and 2B. FIG. 2A is a plan view of the shape defining member 102 (when coupled). FIG. 2B is a plan view of the shape defining member 102 (when divided). As shown in FIGS. 2A and 2B, the shape defining member 102 includes internal shape defining members 102a1, 102a2, 102a3 and an external shape defining member 102b. Here, the cross-sectional views of the internal shape determining members 102a1, 102a2, 102a3 and the external shape determining member 102b in FIG. 1 correspond to the II cross-sectional view in FIG. 2A. Note that the xyz coordinates in FIGS. 2A and 2B coincide with those in FIG.

図２Ａに示すように、外部形状規定部材１０２ｂは、例えば略矩形状の平面形状を有し、中央部に略矩形状の開口部を有している。また、図２Ｂに示すように、外部形状規定部材１０２ｂは、ｙ軸に平行な対称軸に沿って、ｘ軸方向に分割可能である。図２Ａ、２Ｂの例では、外部形状規定部材１０２ｂの四隅はそれぞれ面取り加工されている。また、開口部の四隅にはそれぞれｘ軸方向に突出した突出部が設けられている。   As shown in FIG. 2A, the external shape defining member 102b has, for example, a substantially rectangular planar shape, and has a substantially rectangular opening at the center. As shown in FIG. 2B, the external shape defining member 102b can be divided in the x-axis direction along a symmetry axis parallel to the y-axis. 2A and 2B, the four corners of the external shape defining member 102b are chamfered. In addition, protrusions that protrude in the x-axis direction are provided at the four corners of the opening.

図２Ａに示すように、３つの内部形状規定部材１０２ａ１、１０２ａ２、１０２ａ３はそれぞれ、略矩形状の平面形状を有し、外部形状規定部材１０２ｂの開口部の内部においてｘ軸方向に配列されている。また、図２Ｂに示すように、形状規定部材１０２の中央に位置する内部形状規定部材１０２ａ２は、ｙ軸に平行な対称軸に沿って、ｘ軸方向に分割可能である。内部形状規定部材１０２ａ１、１０２ａ２、１０２ａ３と外部形状規定部材１０２ｂとの間の間隙が、溶湯が通過する溶湯通過部１０２ｃ（ハッチング部）となる。   As shown in FIG. 2A, each of the three internal shape defining members 102a1, 102a2, 102a3 has a substantially rectangular planar shape, and is arranged in the x-axis direction inside the opening of the external shape defining member 102b. . As shown in FIG. 2B, the internal shape defining member 102a2 located at the center of the shape defining member 102 can be divided in the x-axis direction along the symmetry axis parallel to the y-axis. The gaps between the internal shape defining members 102a1, 102a2, 102a3 and the external shape defining member 102b serve as a molten metal passage portion 102c (hatched portion) through which the molten metal passes.

図２Ａ、２Ｂに示すように、形状規定部材１０２は、ｙ軸に平行な対称軸（分割線）に沿って、ｘ軸方向に分割可能である。つまり、形状規定部材１０２は、結合状態と分割状態とを切り換えることができる。そのため、鋳造途中において形状規定部材１０２を結合状態から分割状態へ切り換えることにより、鋳物Ｍ３を分岐させることができる。また、鋳造途中において形状規定部材１０２を分割状態から結合状態へ切り換えることにより、分岐している鋳物Ｍ３を一体化させることができる。すなわち、本実施の形態に係る形状規定部材１０２を用いることにより、分岐構造を有する鋳物Ｍ３を製造することができる。このような分岐構造を有する鋳物Ｍ３の詳細については後述する。   As shown in FIGS. 2A and 2B, the shape defining member 102 can be divided in the x-axis direction along a symmetry axis (partition line) parallel to the y-axis. That is, the shape defining member 102 can be switched between the combined state and the divided state. Therefore, the casting M3 can be branched by switching the shape defining member 102 from the coupled state to the divided state during casting. Further, the casting M3 that is branched can be integrated by switching the shape defining member 102 from the divided state to the coupled state during casting. That is, by using the shape defining member 102 according to the present embodiment, the casting M3 having a branch structure can be manufactured. Details of the casting M3 having such a branched structure will be described later.

次に、図３Ａ、３Ｂを参照して、形状規定部材１０２と連携して鋳物Ｍ３に分岐構造を形成するための溶湯カッターについて説明する。図３Ａは、形状規定部材１０２と溶湯カッターＣ１、Ｃ２との位置関係を示した平面図（形状規定部材１０２の結合時）である。図３Ｂは、形状規定部材１０２と溶湯カッターＣ１、Ｃ２との位置関係を示した平面図（形状規定部材１０２の分割時）である。なお、図３Ａ、３Ｂにおけるｘｙｚ座標は、図１と一致している。   Next, with reference to FIG. 3A and 3B, the molten metal cutter for forming a branch structure in the casting M3 in cooperation with the shape defining member 102 will be described. FIG. 3A is a plan view showing a positional relationship between the shape defining member 102 and the molten metal cutters C1 and C2 (when the shape defining member 102 is coupled). FIG. 3B is a plan view showing the positional relationship between the shape defining member 102 and the molten metal cutters C1 and C2 (when the shape defining member 102 is divided). Note that the xyz coordinates in FIGS. 3A and 3B coincide with those in FIG.

図３Ａ、３Ｂに示すように、Ｙ軸方向に延設された２つの溶湯カッターＣ１、Ｃ２の根元部は、それぞれＸ軸方向に延設されたアームＡ１、Ａ２の一端に固定されている。そして、アームＡ１、Ａ２の他端は、それぞれＹ軸方向に延設されたガイドＧに摺動可能に載置されている。このような構成により、溶湯カッターＣ１、Ｃ２は、Ｙ軸方向に摺動することができる。   As shown in FIGS. 3A and 3B, the base portions of the two melt cutters C1 and C2 extending in the Y-axis direction are fixed to one ends of the arms A1 and A2 extending in the X-axis direction, respectively. The other ends of the arms A1 and A2 are slidably mounted on guides G extending in the Y-axis direction. With such a configuration, the molten metal cutters C1 and C2 can slide in the Y-axis direction.

ここで、ガイドＧは、形状規定部材１０２に追従して、ＸＹ平面上及びＺ軸方向に移動することができる。すなわち、溶湯カッターＣ１、Ｃ２は、形状規定部材１０２に追従して、ＸＹ平面上及びＺ軸方向に移動することができる。溶湯カッターＣ１、Ｃ２は、Ｚ軸方向においては、形状規定部材１０２より上側、凝固界面より下側に配置されている。但し、鋳物Ｍ３の寸法精度を向上させるためには、可能な限り形状規定部材１０２の近くに溶湯カッターＣ１、Ｃ２を設けることが好ましい。   Here, the guide G can follow the shape defining member 102 and move on the XY plane and in the Z-axis direction. That is, the molten metal cutters C1 and C2 can follow the shape defining member 102 and move on the XY plane and in the Z-axis direction. The molten metal cutters C1 and C2 are disposed above the shape defining member 102 and below the solidification interface in the Z-axis direction. However, in order to improve the dimensional accuracy of the casting M3, it is preferable to provide the melt cutters C1 and C2 as close to the shape defining member 102 as possible.

図３Ａに示すように、形状規定部材１０２の結合時には、溶湯カッターＣ１、Ｃ２が、形状規定部材１０２のＹ軸に平行な対称軸上において、形状規定部材１０２から引き上げられた保持溶湯Ｍ２を介して対向配置されている。つまり、溶湯カッターＣ１、Ｃ２は、保持溶湯Ｍ２へ挿入されていない。   As shown in FIG. 3A, when the shape defining member 102 is coupled, the melt cutters C1 and C2 pass through the retained molten metal M2 pulled up from the shape defining member 102 on the axis of symmetry parallel to the Y axis of the shape defining member 102. Are opposed to each other. That is, the molten metal cutters C1 and C2 are not inserted into the retained molten metal M2.

一方、図３Ｂに示すように、形状規定部材１０２の分割時には、溶湯カッターＣ１、Ｃ２が、互いに接近するようにＹ軸方向に移動する。これにより、形状規定部材１０２の分割による保持溶湯Ｍ２の分断を促進する。形状規定部材１０２が分割するだけでは、保持溶湯Ｍ２の表面張力により、保持溶湯Ｍ２が望んだように分断されない恐れがある。そこで、形状規定部材１０２が分割すると同時に、保持溶湯Ｍ２へ溶湯カッターＣ１、Ｃ２を挿入することにより、確実に保持溶湯Ｍ２を分断することができる。これにより、鋳物Ｍ３の分岐構造における寸法精度を向上させることができる。   On the other hand, as shown in FIG. 3B, when the shape defining member 102 is divided, the molten metal cutters C1 and C2 move in the Y-axis direction so as to approach each other. Thereby, the division of the retained molten metal M2 by the division of the shape defining member 102 is promoted. If the shape defining member 102 is only divided, the retained molten metal M2 may not be divided as desired due to the surface tension of the retained molten metal M2. Therefore, the retained molten metal M2 can be reliably divided by inserting the melt cutters C1 and C2 into the retained molten metal M2 at the same time as the shape defining member 102 is divided. Thereby, the dimensional accuracy in the branch structure of the casting M3 can be improved.

次に、図４、５を参照して実施の形態１に係る鋳物Ｍ３について説明する。
図４は、実施の形態１に係る鋳物Ｍ３の斜視図である。図５は、図４におけるＶ−Ｖ切断線による断面斜視図である。実施の形態１に係る鋳物Ｍ３は、例えば自動車の前方に設けられるバンパー（いわゆるフロントバンパー）に使用することができるが、特に用途は限定されない。なお、図４、５におけるｘｙｚ座標は、図１と一致している。また、図４、５に示された鋳物Ｍ３は、あくまでも一例であり、分岐構造を有する鋳物であれば、特に限定されない。 Next, the casting M3 according to the first embodiment will be described with reference to FIGS.
FIG. 4 is a perspective view of the casting M3 according to the first embodiment. 5 is a cross-sectional perspective view taken along the line VV in FIG. The casting M3 according to Embodiment 1 can be used, for example, as a bumper (so-called front bumper) provided in front of the automobile, but the application is not particularly limited. Note that the xyz coordinates in FIGS. 4 and 5 coincide with those in FIG. Moreover, the casting M3 shown by FIG. 4, 5 is an example to the last, and will not be specifically limited if it is a casting which has a branched structure.

図４に示すように、実施の形態１に係る鋳物Ｍ３は、一体部２０１、２０３、分岐部（分岐構造）２０２を備えている。分岐部２０２には、Ｙ軸方向に延びた開口部２０４が設けられている。当該開口部２０４は、例えばフロントバンパーの通気口として利用される。図４に示すように、一体部２０１、２０３は、Ｘ軸方向に並んだ３つの角形パイプＰ１〜Ｐ３が一体化された構造を有している。一体部２０１、２０３は、図２Ａや図３Ａにより示した形状規定部材１０２が結合した状態で形成される。   As shown in FIG. 4, the casting M <b> 3 according to Embodiment 1 includes integral parts 201 and 203 and a branch part (branch structure) 202. The branch part 202 is provided with an opening 204 extending in the Y-axis direction. The opening 204 is used as a vent of a front bumper, for example. As shown in FIG. 4, the integral parts 201 and 203 have a structure in which three rectangular pipes P1 to P3 arranged in the X-axis direction are integrated. The integrated portions 201 and 203 are formed in a state where the shape defining member 102 shown in FIGS. 2A and 3A is coupled.

分岐部２０２では、中央の角形パイプＰ２が縦（Ｚ軸）方向に分割されるとともに、角形パイプＰ１、Ｐ２が互いに離間するように（Ｘ軸方向反対側に）湾曲している。分岐部２０２は、図２Ｂや図３Ｂにより示した形状規定部材１０２が分割した状態で形成される。   In the branch portion 202, the central square pipe P2 is divided in the longitudinal (Z-axis) direction, and the square pipes P1 and P2 are curved so as to be separated from each other (on the opposite side in the X-axis direction). The branch portion 202 is formed in a state where the shape defining member 102 shown in FIGS. 2B and 3B is divided.

より具体的には、鋳造途中において形状規定部材１０２が結合した状態から分割されると、一体部２０１から分岐部２０２の形成に切り換わる。
ここで、形状規定部材１０２の分割幅が拡大するとともに、分岐部２０２における開口部２０４の幅も拡大する。そのため、角形パイプＰ１、Ｐ３の間隔も拡大する。
その後、形状規定部材１０２の分割幅が一定に保持されている間は、分岐部２０２における開口部２０４の幅も一定となり、角形パイプＰ１、Ｐ３は平行となる。
その後、形状規定部材１０２の分割幅が縮小するとともに、分岐部２０２における開口部２０４の幅も縮小する。そのため、角形パイプＰ１、Ｐ３の間隔も縮小する。
そして、鋳造途中において形状規定部材１０２が再結合されると、分岐部２０２から一体部２０３の形成に切り換わる。 More specifically, when the shape defining member 102 is divided from the joined state during casting, the integrated portion 201 is switched to the formation of the branch portion 202.
Here, the division width of the shape defining member 102 is increased, and the width of the opening 204 in the branch portion 202 is also increased. Therefore, the interval between the square pipes P1, P3 is also increased.
Thereafter, while the divided width of the shape defining member 102 is kept constant, the width of the opening 204 in the branch portion 202 is also constant, and the square pipes P1 and P3 are parallel.
Thereafter, the division width of the shape defining member 102 is reduced, and the width of the opening 204 in the branch portion 202 is also reduced. Therefore, the interval between the square pipes P1 and P3 is also reduced.
When the shape defining member 102 is re-coupled during casting, the branch portion 202 is switched to the formation of the integrated portion 203.

次に、図１を参照して、実施の形態１に係る自由鋳造方法について説明する。
まず、スタータＳＴを降下させ、形状規定部材１０２が結合した状態における内部形状規定部材１０２ａ１、１０２ａ２、１０２ａ３と外部形状規定部材１０２ｂとの間の溶湯通過部１０２ｃを通して、スタータＳＴの先端部を溶湯Ｍ１に浸漬させる。スタータＳＴとしては鋳物Ｍ３の一体部２０１と同じ断面形状を有し、長手方向に直線状に延びたものを用いることが好ましい。 Next, the free casting method according to Embodiment 1 will be described with reference to FIG.
First, the starter ST is lowered, and the tip of the starter ST is passed through the molten metal passage portion 102c between the internal shape determining members 102a1, 102a2, 102a3 and the external shape determining member 102b in a state in which the shape determining member 102 is coupled. Soak in. It is preferable to use a starter ST that has the same cross-sectional shape as the integral part 201 of the casting M3 and extends linearly in the longitudinal direction.

次に、所定の速度でスタータＳＴの引き上げを開始する。ここで、スタータＳＴが湯面から離間しても、表面膜や表面張力によって、スタータＳＴに追従して湯面から引き上げられた保持溶湯Ｍ２が形成される。図１に示すように、保持溶湯Ｍ２は、内部形状規定部材１０２ａ１、１０２ａ２、１０２ａ３と外部形状規定部材１０２ｂとの間の溶湯通過部１０２ｃに形成される。つまり、内部形状規定部材１０２ａ１、１０２ａ２、１０２ａ３と外部形状規定部材１０２ｂとにより、保持溶湯Ｍ２に形状が付与される。   Next, the starter ST is started to be pulled up at a predetermined speed. Here, even if the starter ST is separated from the molten metal surface, the retained molten metal M2 pulled up from the molten metal surface following the starter ST is formed by the surface film or surface tension. As shown in FIG. 1, the retained molten metal M2 is formed in the molten metal passage portion 102c between the inner shape defining members 102a1, 102a2, 102a3 and the outer shape defining member 102b. That is, the shape is imparted to the retained molten metal M2 by the inner shape defining members 102a1, 102a2, 102a3 and the outer shape defining member 102b.

次に、スタータＳＴは、内部冷却ガスノズル１０３及び外部冷却ガスノズル１０６から吹き出される冷却ガスにより冷却されているため、保持溶湯Ｍ２が上側から下側に向かって順に凝固し、鋳物Ｍ３が成長していく。このようにして、鋳物Ｍ３を連続鋳造することができる。   Next, since the starter ST is cooled by the cooling gas blown from the internal cooling gas nozzle 103 and the external cooling gas nozzle 106, the retained molten metal M2 is solidified in order from the upper side to the lower side, and the casting M3 grows. Go. In this way, the casting M3 can be continuously cast.

上述の通り、実施の形態１に係る自由鋳造方法では、最初に、形状規定部材１０２が結合された状態（図２Ａ、図３Ａ参照）で一体部２０１（図４参照）が形成される。次に、形状規定部材１０２が分割された状態（図２Ｂ、図３Ｂ参照）で分岐部２０２（図４参照）が形成される。最後に、形状規定部材１０２が再結合されることにより（図２Ａ、図３Ａ参照）、一体部２０３（図４参照）が形成される。   As described above, in the free casting method according to the first embodiment, first, the integrated portion 201 (see FIG. 4) is formed in a state where the shape defining member 102 is coupled (see FIGS. 2A and 3A). Next, the branch portion 202 (see FIG. 4) is formed in a state where the shape defining member 102 is divided (see FIGS. 2B and 3B). Finally, the shape defining member 102 is recombined (see FIGS. 2A and 3A) to form the integrated portion 203 (see FIG. 4).

なお、内部形状規定部材１０２ａ１、１０２ａ２、１０２ａ３及び外部形状規定部材１０２ｂの相対位置関係を維持したまま、形状規定部材１０２を水平方向に移動させることもできる。これにより、分岐構造以外にも、鋳物Ｍ３に種々の屈曲部や湾曲部を付与することができる。   The shape defining member 102 can also be moved in the horizontal direction while maintaining the relative positional relationship between the internal shape defining members 102a1, 102a2, 102a3 and the external shape defining member 102b. Thereby, besides a branched structure, various bending parts and curved parts can be given to casting M3.

なお、内部形状規定部材１０２ａ１、１０２ａ２、１０２ａ３及び外部形状規定部材１０２ｂを水平方向に移動させる代わりに、引上機に固定されたスタータＳＴを水平方向に移動させてもよい。あるいは、内部形状規定部材１０２ａ１、１０２ａ２、１０２ａ３及び外部形状規定部材１０２ｂと、スタータＳＴとを水平面内において反対方向に移動させてもよい。   Instead of moving the internal shape defining members 102a1, 102a2, 102a3 and the external shape defining member 102b in the horizontal direction, the starter ST fixed to the pulling machine may be moved in the horizontal direction. Alternatively, the internal shape defining members 102a1, 102a2, 102a3, the external shape defining member 102b, and the starter ST may be moved in opposite directions within the horizontal plane.

なお、本発明は上記実施の形態に限られたものではなく、趣旨を逸脱しない範囲で適宜変更することが可能である。特に、鋳物Ｍ３は中空（パイプ）構造でなく、中実構造であってもよい。   Note that the present invention is not limited to the above-described embodiment, and can be changed as appropriate without departing from the spirit of the present invention. In particular, the casting M3 may have a solid structure instead of a hollow (pipe) structure.
