Description

本発明は、鋳型に注湯する注湯取鍋に合金成分材が投入された溶解炉からの溶湯を供給する処理取鍋に、溶解炉から溶湯を供給する方法およびその装置に関する。 The present invention relates to a method and an apparatus for supplying molten metal from a melting furnace to a treatment ladle that supplies molten metal from a melting furnace in which an alloy component material is charged into a pouring ladle that is poured into a mold.

従来、鋳物製品を鋳造する鋳造ラインの一つとして、溶湯の材質を変える合金成分材を合金成分材投入装置から受ける処理取鍋を、溶解炉（保持炉）と注湯取鍋台車装置の移動経路との間に設けて、処理取鍋が合金成分材投入装置からの合金成分材と溶解炉からの溶湯を受けた後、処理取鍋の合金成分材が投入された溶湯を注湯取鍋台車装置の注湯取鍋に移し替えるようにしたものがある。   Conventionally, as one of the casting lines for casting products, the processing ladle that receives the alloy component material that changes the material of the molten metal from the alloy component material charging device is moved between the melting furnace (holding furnace) and the pouring ladle cart device After the processing ladle has received the alloy component material from the alloy component material charging device and the molten metal from the melting furnace, the molten metal into which the alloy component material of the processing ladle has been charged is poured into the pouring ladle.

ところで、このように構成された従来の鋳造ラインでは、溶解炉を傾動して溶湯を処理取鍋に供給する際、溶湯が処理取鍋の外に飛散しないように、かつ、溶湯を処理取鍋に必要量、精度良く供給する要求がある。しかし溶解炉から流出する溶湯の一部が処理取鍋から飛び出したり、溶解炉の傾動速度および傾動位置により溶解炉からの溶湯の流出量が変動することがある。このため、作業者は、溶解炉の傾動速度および傾動位置に多大の神経を使いながら溶解炉から処理取鍋に溶湯を供給しており、作業者に重労働を課している。
このため、業界から、溶解炉から処理取鍋への溶湯の供給を自動的・機械的に行うことが可能な方法および装置の開発が要望されていた。By the way, in the conventional casting line configured in this way, when the molten furnace is tilted and the molten metal is supplied to the processing ladle, the molten metal is prevented from splashing out of the processing ladle and the molten metal is processed into the processing ladle. There is a need to supply the required amount with high accuracy. However, a part of the molten metal flowing out from the melting furnace may jump out of the processing ladle, or the amount of molten metal flowing out from the melting furnace may vary depending on the tilting speed and tilting position of the melting furnace. For this reason, the worker supplies molten metal from the melting furnace to the treatment ladle while using a great deal of nerves in the tilting speed and tilting position of the melting furnace, which imposes heavy labor on the worker.
For this reason, the development of a method and apparatus capable of automatically and mechanically supplying molten metal from a melting furnace to a treatment ladle has been demanded by the industry.

本発明は叙上の事情に鑑みてなされたもので、その目的は、溶解炉から処理取鍋への溶湯の供給を自動的・機械的に行うことが可能な方法および装置を提供することにある。 The present invention has been made in view of the above circumstances, and an object thereof is to provide a method and an apparatus capable of automatically and mechanically supplying molten metal from a melting furnace to a treatment ladle. is there.

また、本発明における溶湯の溶解炉から処理取鍋への供給方法は、溶解炉の傾動速度および傾動位置を制御するとともに、処理取鍋の位置を溶解炉に対して前後に移動制御することにより、溶解炉から流出する溶湯の描く出湯流線の下端が処理取鍋内の所定位置に位置するようになる様に溶解炉から処理取鍋に溶湯を供給することを特徴とする。In order to achieve the above object, the method of supplying the molten metal from the melting furnace to the treatment ladle according to the present invention controls the tilting speed and tilting position of the melting furnace, and the lower end of the outlet stream line drawn by the molten metal flowing out of the melting furnace is The molten metal is supplied from the melting furnace to the treatment ladle so as to be located in the treatment ladle.
In addition, the method for supplying molten metal from the melting furnace to the treatment ladle according to the present invention controls the tilting speed and tilting position of the melting furnace, and controls the movement of the position of the treatment ladle relative to the melting furnace. The molten metal is supplied from the melting furnace to the treatment ladle so that the lower end of the molten metal flowing out of the melting furnace is positioned at a predetermined position in the treatment ladle.

以上の説明から明らかなように、本発明は、溶解炉の傾動速度および傾動位置と処理取鍋の前後位置を制御し、溶解炉から流出する溶湯の描く出湯流線の下端が処理取鍋内に位置するようになる様に溶解炉から処理取鍋に溶湯を供給するものであり、溶解炉から処理取鍋への溶湯の供給を自動的・機械的に行うことが可能になるなどの優れた実用的効果を奏する。
加えて、溶解炉の傾動駆動を電動駆動にしたことで、高温の溶湯から油圧用のオイルを接近させることがなくなり、安全性が高くなった。As is clear from the above description, the present invention controls the tilting speed and tilting position of the melting furnace and the front and rear positions of the treatment ladle, and the lower end of the discharge stream drawn by the molten metal flowing out of the melting furnace is in the treatment ladle. The molten metal is supplied from the melting furnace to the treatment ladle so that it can be located in the furnace, and the molten metal can be automatically and mechanically supplied from the melting furnace to the treatment ladle. Has a practical effect.
In addition, since the tilting drive of the melting furnace is an electric drive, the oil for hydraulic pressure is not approached from the high-temperature molten metal, and safety is improved.

このように構成したものは、合金成分材投入装置（図示せず）から合金成分材を処理取鍋台車４の処理取鍋３に投入した後、その処理取鍋３を台車本体１３により溶解装置２と対向する位置まで移送し、続いて、図５に示すように、制御装置７の管理の下に、溶解装置２の電動シリンダ１１のサーボモータを正回転させて溶解装置２の溶解炉１を処理取鍋３に向けて傾動する。そして、溶解炉１の傾動に際し、溶解炉１の傾動速度および傾動位置を制御して溶解炉１から流出する溶湯が描く出湯流線の下端が処理取鍋３内に位置するようにする。
また、図６のように構成したものは、更に、溶解炉１の傾動に際し、溶解炉１の傾動速度および傾動位置を制御するとともに、処理取鍋の前後位置又は上下（昇降）位置を、溶解炉１の傾動角度値に合わせて移動させることにより、溶解炉１から流出する溶湯が描く出湯流線の下端が処理取鍋３内の所定位置に位置するようにする。What comprised in this way is, after putting an alloy component material into the treatment ladle 3 of the treatment ladle trolley 4 from an alloy component material charging device (not shown), the treatment ladle 3 is melted by the trolley body 13. 2, and subsequently, as shown in FIG. 5, under the control of the control device 7, the servo motor of the electric cylinder 11 of the melting device 2 is rotated forward to melt the melting furnace 1 of the melting device 2. Is tilted toward the processing ladle 3. Then, when the melting furnace 1 is tilted, the tilting speed and tilting position of the melting furnace 1 are controlled so that the lower end of the outgoing stream line drawn by the molten metal flowing out of the melting furnace 1 is positioned in the treatment ladle 3.
Further, in the configuration as shown in FIG. 6, when the melting furnace 1 is tilted, the tilting speed and the tilting position of the melting furnace 1 are controlled, and the front / rear position or the vertical (up / down) position of the treatment ladle is melted. By moving according to the tilt angle value of the furnace 1, the lower end of the tapping stream drawn by the molten metal flowing out of the melting furnace 1 is positioned at a predetermined position in the treatment ladle 3.

すなわち、制御装置７に傾動開始指令が入力されると、予め傾動速度記憶手段７２に記憶している溶解炉１の傾動速度を読み出して傾動速度指示手段７３で溶解炉１の傾動速度を決定する。そして、傾動開始指示手段７１からサーボモータ駆動指示手段７９に溶解炉１の駆動開始指示が送信されて電動シリンダ１１のサーボモータが駆動され、溶解炉１の傾動が開始する。こうして、電動シリンダ１１のサーボモータが駆動されている時、電動シリンダ１１のサーボモータのエンコーダから傾動速度・位置測定手段７４に溶解炉１の傾動速度・傾動位置情報が送信されて、サーボモータ駆動指示手段７９により、逐次、溶解炉１の傾動速度・傾動位置が補正される。同時に溶解炉の傾動角度値に合わせて、処理取鍋の前後位置又は上下（昇降）位置を補正しても良い。 That is, when a tilt start command is input to the control device 7, the tilt speed of the melting furnace 1 previously stored in the tilt speed storage means 72 is read and the tilt speed of the melting furnace 1 is determined by the tilt speed instruction means 73. . Then, an instruction to start driving the melting furnace 1 is transmitted from the tilt start instructing means 71 to the servo motor drive instructing means 79, the servo motor of the electric cylinder 11 is driven, and the tilting of the melting furnace 1 starts. Thus, when the servo motor of the electric cylinder 11 is being driven, the tilt speed / tilt position information of the melting furnace 1 is transmitted from the encoder of the servo motor of the electric cylinder 11 to the tilt speed / position measuring means 74 to drive the servo motor. By the instruction means 79, the tilting speed and tilting position of the melting furnace 1 are sequentially corrected. At the same time, the front / rear position or the vertical (lifting / lowering) position of the treatment ladle may be corrected according to the tilt angle value of the melting furnace.

一方、処理取鍋台車４のロードセル１４からの送信により溶湯重量測定手段７５が処理取鍋３の溶湯重量を決定し、供給溶湯重量記憶手段７６から予定している処理取鍋３内の溶湯重量値を読み出して、湯切り判定手段７７が処理取鍋３の溶湯重量と予定している処理取鍋３内の溶湯重量値を比較して湯切り時期を決定する。湯切時期にきたら、湯切り判定手段７７がサーボモータ駆動指示手段７９に送信して、電動シリンダ１１のサーボモータの停止と溶解炉１の水平位置復帰指示をサーボモータ駆動指示手段７９に指示する。その後、サーボモータ駆動指示手段７９が電動シリンダ１１のサーボモータに送信して電動シリンダ１１のサーボモータを停止させたのち逆回転させて溶解炉１を水平状態に復帰させる。
これにより、溶解炉１から処理取鍋３への溶湯の供給を自動的・機械的に行うことができる。On the other hand, the molten metal weight measurement means 75 determines the molten metal weight of the treatment ladle 3 by transmission from the load cell 14 of the treatment ladle carriage 4, and the molten metal weight in the treatment ladle 3 scheduled from the supplied molten metal weight storage means 76. The value is read out, and the hot water cutting judging means 77 compares the molten metal weight of the processing ladle 3 with the scheduled molten metal weight value in the processing ladle 3 to determine the hot water cutting time. When the hot water cut time is reached, the hot water cut determining means 77 transmits to the servo motor drive instructing means 79 to instruct the servo motor drive instructing means 79 to stop the servo motor of the electric cylinder 11 and to return the horizontal position of the melting furnace 1. . Thereafter, the servo motor drive instructing means 79 transmits to the servo motor of the electric cylinder 11 to stop the servo motor of the electric cylinder 11 and then reversely rotates to return the melting furnace 1 to the horizontal state.
Thereby, the molten metal can be automatically and mechanically supplied from the melting furnace 1 to the treatment ladle 3.

なお、本発明において処理取鍋台車４は、駆動機構１２により図２の左右方向に走行可能にし、駆動機構１５により処理取鍋３を前後方向へ移送可能にしている。溶解炉１の傾動角度毎の出湯流線の位置をあらかじめ記憶させておき、溶解炉１の傾動角度に合わせて処理取鍋を前後に移動することにより、出湯流線の下端を処理取鍋内の所定位置に合わせることができる。
ローラーコンベヤーを採用しない場合は、パンタグラフ状のリフターなどの別の駆動機構により処理取鍋３を直接又は間接的に昇降（上下）させるようにしても良い。このようにすると、溶解炉１から処理取鍋３までの高低差を小さくできるのでさらに安定した溶湯の供給、即ち受湯をすることができる。In the present invention, the processing ladle cart 4 can be moved in the left-right direction in FIG. 2 by the drive mechanism 12, and the processing ladle 3 can be transferred in the front-rear direction by the drive mechanism 15. The position of the tapping streamline for each tilt angle of the melting furnace 1 is stored in advance, and the lower end of the tapping streamline is moved into the processing ladle by moving the processing ladle back and forth according to the tilting angle of the melting furnace 1. Can be adjusted to a predetermined position.
When not using a roller conveyor, you may make it raise / lower (up and down) the processing ladle 3 directly or indirectly by another drive mechanisms, such as a pantograph-like lifter. In this way, the difference in elevation from the melting furnace 1 to the treatment ladle 3 can be reduced, so that a more stable supply of molten metal, that is, hot water can be received.

なお、本発明の溶湯の溶解炉から処理取鍋への供給システムは、処理取鍋台車のローラーコンベヤ移動位置指示手段８０及びリフターの上下移動位置指示手段８１のいずれか又は両方を兼ね備えていても良い。 The system for supplying molten metal from the melting furnace of the present invention to the processing ladle may have either or both of the roller conveyor movement position instruction means 80 and the lifter vertical movement position instruction means 81 of the treatment ladle carriage. good.
