Description
本発明においては、補強枠の高さは、断熱枠の高さより高いことが好ましい。
また、本発明においては、断熱枠上面と、タンディッシュ下面の間に、ノズル周囲から断熱枠上面までを覆う断熱シートが配置されていることが好ましい。
In the present invention, the height of the reinforcing frame is preferably higher than the height of the heat insulating frame.
In the present invention, and the heat insulating frame top, between the lower surface tundish, it is preferable that the heat insulating sheet covering from around the nozzle to the heat insulating frame upper surface is arranged.
まず、図１および図２に示すように本発明の柱状インゴットの鋳造装置は、複数本の柱状鋳型５を用いる。柱状インゴットは、先に記載したようにマスターメタルの使用形状にとって有利であり、複数同時鋳造法によれば生産性に優れている。鋳型形状は柱状であればよく断面は矩形であっても円形であってもよいが、鋳型製造性および作業性（補強枠を用いたときの鋳型位置決めの容易性）の面からは円形が好ましい。鋳型としては溶湯との反応性の低い材質が好ましい。一般的にはコストを考慮して、炭素鋼を適用することができる。
また、鋳型のサイズとしては、内径５０〜２００ｍｍ、長さ５００〜２０００ｍｍが典型である。
本発明では、図１に示すように、鋳型底部より順次凝固させるための冷し金６を配置した定盤７を準備し、その上に中空円柱状の鋳型５を配置することで、マトリックス状に鋳型を組むことができる。使用する典型的な冷し金６の材質は銅であり、定盤７の材質は鋳鉄である。
First, as shown in FIGS. 1 and 2, the columnar ingot casting apparatus of the present invention uses a plurality of columnar molds 5. As described above, the columnar ingot is advantageous for the use shape of the master metal, and is excellent in productivity according to the multiple simultaneous casting method. Mold shape may be may sectional long columnar be circular be rectangular but is preferably circular from the viewpoint of the mold fabrication and workability (ease of mold positioning when using a reinforcing frame) . As the mold, a material having low reactivity with the molten metal is preferable. In general, carbon steel can be applied in consideration of cost.
Moreover, as a size of a casting_mold | template, internal diameter 50-200mm and length 500-2000mm are typical.
In the present invention, as shown in FIG. 1, a matrix 7 is prepared by preparing a platen 7 on which cooling metal 6 for solidifying sequentially from the bottom of the mold is arranged, and placing a hollow cylindrical mold 5 thereon. A mold can be assembled. The material of the typical cooling metal 6 to be used is copper, and the material of the surface plate 7 is cast iron.
上述した断熱枠４を配置したタンディッシュ１を、断熱枠下部端面が柱状鋳型５の上部端面に接触接続するように載置することで、図１および図２に示す本発明の鋳造装置となる。
本発明の鋳造装置は、断熱枠４により、柱状鋳型５毎の断熱空間が形成される。これにより、ノズル３の閉塞の要因となるノズル３近傍の抜熱を確実に抑制することができる。
なお、図３に示すように、断熱枠４上面と、タンディッシュ１の下面の間に、ノズル３周囲から断熱枠４上面までを覆う断熱シート４ａを配置してもよい。断熱シート４ａにより、タンディッシュ１の下面と断熱枠４の境界からの抜熱をさらに低減でき、ノズル３閉塞の発生をさらに抑制できる。断熱シート４ａとしてはアルミナ・シリカ系セラミックファイバ等が利用できる。
また、本発明の鋳造装置においては、断熱枠４の下部端面と柱状鋳型５の上部端面とは、断熱枠４側の自重により接続される。この構造は、組み立て容易性はもちろん、鋳造後のインゴットからの断熱枠４の分離除去性にも優れるものとなる。
また、柱状鋳型５と断熱枠４の載置接続する面の構成として、断熱枠４の下部端面と柱状鋳型５の上部端面とは、お互いに補角となるようなテーパーを形成することが好ましい。これにより位置決めがより容易となる。
By placing the tundish 1 on which the heat insulating frame 4 described above is disposed so that the lower end surface of the heat insulating frame is in contact with the upper end surface of the columnar mold 5, the casting apparatus of the present invention shown in FIGS. 1 and 2 is obtained. .
In the casting apparatus of the present invention, a heat insulating space for each columnar mold 5 is formed by the heat insulating frame 4. Thereby, the heat removal in the vicinity of the nozzle 3 that causes the nozzle 3 to be blocked can be reliably suppressed.
As shown in FIG. 3, and the heat insulating frame 4 top, between the lower surface of the tundish 1, it may be arranged a heat insulating sheet 4a which covers from the nozzles 3 around to adiabatic frame 4 top. With the heat insulating sheet 4a, heat removal from the lower surface of the tundish 1 and the boundary between the heat insulating frames 4 can be further reduced, and the occurrence of nozzle 3 blockage can be further suppressed. An alumina / silica ceramic fiber or the like can be used as the heat insulating sheet 4a.
In the casting apparatus of the present invention, the lower end surface of the heat insulating frame 4 and the upper end surface of the columnar mold 5 are connected by their own weight on the heat insulating frame 4 side. This structure is excellent not only in ease of assembly but also in the ability to separate and remove the heat insulating frame 4 from the ingot after casting.
Further, as a configuration of the surface on which the columnar mold 5 and the heat insulating frame 4 are placed and connected, it is preferable that the lower end surface of the heat insulating frame 4 and the upper end surface of the columnar mold 5 are tapered so as to be complementary to each other. . This makes positioning easier.
