【考案の詳細な説明】
本考案は、連続鋳造における電磁誘導攪拌装置に関する
ものである。[Detailed Description of the Invention] The present invention relates to an electromagnetic induction stirring device for continuous casting.
鋳造中の鋳片未凝固部を電磁誘導により攪拌し、内部組
織を改善することが知られている。It is known that the unsolidified part of a cast slab during casting is stirred by electromagnetic induction to improve its internal structure.
一方、最近鋳造中に鋳片山を変更する技術が開発され、
又異鋼種を連続鋳造することも開発された。On the other hand, a technology has recently been developed to change the slab pile during casting.
Continuous casting of different steel grades was also developed.
しかして、このような巾変更部位の未凝固部の攪拌を他
の部位と同様に攪拌すると、鋳片の凝固部（外皮）が破
れるおそれがあり、又異鋼種の継目部においては、同様
に仕切板等を鋳型内溶鋼に配置し異鋼種の混合域を少な
くしておりこの部位も通常の攪拌力を与えると、凝固部
が破れるおそれがある等の欠点をともなうものである。However, if the unsolidified part of such a width changing part is stirred in the same way as other parts, there is a risk that the solidified part (outer skin) of the slab will break, and the same problem will occur at the joint part of different steel types. A partition plate or the like is placed in the molten steel in the mold to reduce the area where different steel types are mixed, and if normal stirring force is applied to this area, there is a risk that the solidified portion may break.
本考案はこのような欠点を有利に解決するためになされ

片幅変更部位又は継目部位変質部移動距離検出器を鋳片
移動位置に設置し、該検出器と電磁誘導攪拌調整器とを
連係せしめた連続鋳造における電磁誘導攪拌装置に関す
るものである。The present invention has been developed to advantageously solve these drawbacks, and its feature is that during continuous casting, the movement distance detector of the changed part of the slab width or the joint part is moved to the position of the slab movement. The present invention relates to an electromagnetic induction stirring device for continuous casting in which the detector and the electromagnetic induction stirring regulator are connected.
即ち本考案においては前記のごとき鋳造中の巾変更部位
、継目部位等の変質部移動を検出し、これに基づき電磁
誘導攪拌器の電流、周波数等を変更して鋳片の変質部位
の攪拌力を弱め前記のごとき欠点を解消しようとするも
のである。In other words, in the present invention, the movement of altered parts such as the width changing area and joint area during casting is detected, and based on this, the current, frequency, etc. of the electromagnetic induction stirrer are changed to increase the stirring force of the altered area of the slab. This is an attempt to weaken the power and eliminate the above-mentioned drawbacks.
かくすることにより鋳片の変質部での凝固部の破れを確
実に防止でき、品質を向上するとともに操業の、安全を
計り得る等の優れた効果が得られるものである。By doing so, it is possible to reliably prevent breakage of the solidified part in the altered part of the slab, resulting in excellent effects such as improving quality and ensuring operational safety.
次に本考案の実施態様を説明する。Next, embodiments of the present invention will be described.
図面において、連続鋳造鋳片１の移動位置に鋳片変質部
移動距離検出器２（例えばパルスジェネレーター等）を
設は電磁誘導攪拌器３の電磁誘導攪拌調整器４と連係せ
しめる。In the drawing, a slab deterioration part movement distance detector 2 (for example, a pulse generator, etc.) is provided at a moving position of the continuously cast slab 1 and is linked to an electromagnetic induction stirring regulator 4 of an electromagnetic induction stirrer 3.
しかして鋳型５において、鋳片１の巾変更又は異鋼種の
鋳込が行なわれたとき、操作ボタン６により検出器２へ
その位置を発信し、次いで鋳片１の移動にともない検出
器２はパルスを調整器４へ送信する、つまり鋳型５と電
磁誘導攪拌器３の距離を調整器４にセットしておき、鋳
片１の移動に従いパルスを調整器４へ送り、変質部位（
巾変更部位等）が電磁誘導攪拌器３に近づいたとき、調
整器４は電流を低くして電磁力を弱めるか又は周波数を
変更して鋳片１の変質部位の攪拌力を弱め該部位が攪拌
器３を通過し電磁力の影響が小さくなったとき調整器４
が、もとの電流又は周波数に調整する。Therefore, when the width of the slab 1 is changed or a different steel type is cast in the mold 5, the operation button 6 transmits the position to the detector 2, and as the slab 1 moves, the detector 2 The pulse is sent to the regulator 4, that is, the distance between the mold 5 and the electromagnetic induction stirrer 3 is set in the regulator 4, and the pulse is sent to the regulator 4 as the slab 1 moves, and the altered area (
When the width changing area, etc.) approaches the electromagnetic induction stirrer 3, the regulator 4 lowers the current to weaken the electromagnetic force or changes the frequency to weaken the stirring force at the altered area of the slab 1. When the influence of electromagnetic force becomes smaller after passing through the stirrer 3, the regulator 4
adjusts to the original current or frequency.
又別の態様として例えば電磁誘導攪拌器を鋳片１に対し
て間隔調整自在に油圧シリンダー等を介して設け、上記
のごとき態様に際し調整器４からの信号により油圧シリ
ンダーを操作し攪拌器３を鋳片１から遠ざけて攪拌力を
弱めることもできる。In another embodiment, for example, an electromagnetic induction stirrer is provided to the slab 1 via a hydraulic cylinder or the like so that the interval can be freely adjusted. It is also possible to weaken the stirring force by moving it away from the slab 1.
