【考案の詳細な説明】 [考案の目的] (産業上の利用分野) 本考案は鋳型に直接注湯する誘導溶解炉に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial field of application) The present invention relates to an induction melting furnace for directly pouring molten metal into a mold.
(従来の技術) 従来鋳造ラインでは、誘導溶解炉で加熱溶解した溶湯
を少量ずつパドルや取鍋に受けて、ここから間欠的に搬
送装置で送られてくる鋳型に順次注湯している。(Prior Art) In a conventional casting line, a molten metal heated and melted in an induction melting furnace is received little by little in a paddle or a ladle, and the molten metal is intermittently poured into a mold which is intermittently fed from here by a transfer device.
このようにパドルや取鍋で溶湯を一旦受けてから鋳型
に注湯するため、注湯温度の低下が避けられなかった。Since the molten metal is once received by the paddle or ladle and then poured into the mold as described above, a decrease in the pouring temperature cannot be avoided.
このため温度降下分を予め見込んで溶解温度を高くし
て溶解しているが、温度を高くするとエネルギーコスト
が高くなるばかりか、昇温し過ぎると酸化などにより製
品不良の原因となることがあった。For this reason, the temperature drop is expected in advance and the melting temperature is raised to cause melting.However, raising the temperature not only raises the energy cost, but too high a temperature may cause product failure due to oxidation or the like. It was
また誘導溶解炉から鋳型に直接注湯する場合、誘導溶
解炉と搬送されてくる鋳型とは衝突しないように、この
間に間隔を設けて配置されているので、湯口から鋳型ま
での間に溶湯を導く長い樋が必要となる。In addition, when pouring molten metal directly from the induction melting furnace into the mold, the molten metal is placed between the sprue and the mold, because the induction melting furnace and the mold being conveyed do not collide with each other because there is a gap between them. A long gutter to guide is needed.
しかしながらこの長い樋を溶湯が通過する時に同様に
温度が降下するので樋をバーナーで加熱しているが、こ
のときバーナーの燃焼ガスが溶湯に巻き込まれて製品不
良の原因となる問題もあった。However, since the temperature similarly drops when the molten metal passes through this long gutter, the gutter is heated by the burner. However, at this time, there is a problem that the burner combustion gas is caught in the molten metal and causes defective products.
また湯口を長く形成することも考えられるが、湯口を
長くすると傾動ヒンジが湯口の先端側に位置しているの
で、溶湯を完全に排出するために炉体を高く傾動させな
ければならず、このためスタンドや傾動シリンダーが大
型化する問題がある。It is also possible to make the sprue longer, but when the sprue is made longer, the tilting hinge is located at the tip side of the sprue, so the furnace body must be tilted high in order to completely discharge the molten metal. Therefore, there is a problem that the stand and the tilt cylinder become large.
(考案が解決しようとする問題点) 本考案は、上記欠点を除去し炉体の湯口を鋳型に近付
けて直湯できるので、溶解温度を注湯温度とほぼ等しく
してエネルギーコストを安くできると共に、鋳造製品の
品質を向上させた誘導溶解炉を提供するものである。(Problems to be solved by the invention) The present invention eliminates the above-mentioned drawbacks and makes it possible to bring the hot spout of the furnace body close to the mold so that direct hot water can be obtained, so that the melting temperature can be made almost equal to the pouring temperature and the energy cost can be reduced. , An induction melting furnace with improved quality of cast products.
[考案の構成] (問題点を解決するための手段) 本考案は炉体をスタンドに傾動自在に支持すると共
に、スタンドの上部にガイドアームを前方に向って突設

ーを接続したことを特徴とするものである。[Structure of the Invention] (Means for Solving Problems) The present invention supports the furnace body on a stand so that the furnace body can be tilted, and a guide arm is provided on the upper part of the stand so as to project forward. The tilting hinge of the furnace body is movably attached, and a transverse cylinder is connected to the tilting hinge.
(作用) 本考案の作用について説明すると、溶解材料を誘導溶
解炉に投入して誘導加熱し、溶湯ができたらこの状態で
待機する。(Operation) The operation of the present invention will be described. The molten material is put into an induction melting furnace to be induction-heated, and when the molten metal is formed, it waits in this state.

A furnace body 1 made of refractory material and formed in a crucible shape is supported by a stand 2. The furnace body 1 is rotatably supported by a tilting hinge 4 attached to the upper part of the stand 2 at the tip side of the furnace body 3, and both sides of the furnace body 1 are supported by tilting cylinders 5 and 5 as shown in FIG. It is connected to the base of 2 and tilts.
前記スタンド2はその上部に第3図に示すように前方
に向って2本のガイドアーム6、6が水平に突設されて
いる。As shown in FIG. 3, the stand 2 is provided with two guide arms 6, 6 horizontally projecting forward as shown in FIG.

動自在に取付けられ、更にこの傾動ヒンジ4の後端部
は、スタンド2の上部に取付けた横動シリンダー7に接
続されている。The tilting hinge 4 is slidably mounted on the guide arm 6, and the rear end of the tilting hinge 4 is connected to a traverse cylinder 7 mounted on the upper portion of the stand 2.
8は誘導溶解炉の前方に配置された鋳型で、搬送装置
9により間欠的に移動するようになっている。Reference numeral 8 denotes a mold arranged in front of the induction melting furnace, which is intermittently moved by the transfer device 9.
次に上記装置の動作について説明すると、第1図に示
すように溶解材料を炉体1に投入して誘導加熱する。Next, the operation of the above apparatus will be described. As shown in FIG. 1, the molten material is charged into the furnace body 1 and induction heating is performed.

シリンダー5を駆動させてピストンを伸出させると同時
に横動シリンダー7のピストンを伸出させて傾動ヒンジ
4を押し出してガイドアーム6上を前方に移動させる。When the molten metal is produced, it stands by in this state, and when the mold 8 conveyed by the conveying device 9 stops in front of the induction melting furnace, the tilting cylinder 5 is driven to extend the piston and at the same time, the piston of the lateral moving cylinder 7 Is extended and the tilting hinge 4 is pushed out to move the guide arm 6 forward.

すると、炉体1は第1図に仮想線で示すように傾動ヒン
ジ4を支点として傾動しながら湯口3が前方に移動して
鋳型8に近付き、ここから鋳型8に注湯される。When the tilting cylinder 5 and the traversing cylinder 7 are driven simultaneously, the furnace body 1 tilts with the tilting hinge 4 as a fulcrum as shown in phantom in FIG. 1, and the gate 3 moves forward to approach the mold 8. From here, it is poured into the mold 8.
このように注湯時に湯口3がガイドアーム6にガイド
されて前方に移動して鋳型9との距離が短縮されるの
で、樋を通さずに直接注湯することができ、温度降下せ
ずに適正な注湯温度で鋳込むことができる。In this way, when pouring, the sprue 3 is guided by the guide arm 6 and moves forward to shorten the distance from the mold 9, so that the pouring can be performed directly without passing through the gutter, and the temperature does not drop. Can be cast at an appropriate pouring temperature.
