九、發明說明: 【發明所屬之技術領域】 本發明係有關金屬,尤其是鋼的連續鑄造。特別是有 關扁平產品(亦即細長截面者)鑄造時的電磁攪拌,=至 更精確而言,係有關於金屬液體池中利用外加磁場建立流 動的特殊分佈。 【先前技術】 請注意應瞭解-般說法「細長截面的產品」係表示寬 度至少是厚度兩倍的冶金產品,尤其是板坯小塊料薄 板坯等。 七〇年代初期出現在連續鑄鋼領域,電磁攪拌已迅速 確定其作為固化時控制液體池内流動之幾乎為必需工具的 地位。記得最常用的原理是吾人所熟知的Mhd (磁流體 動力學)原理,其利用放置在與鑄件相鄰的一個多相感應 盗,或大體而言為數個多相感應器所產生的移動(轉動或 仃進)磁場以其位移驅動液態金屬。適當地位於鑄造機之 冶金高度的這些感應器係供以可調頻率之電流,藉此提供 各種能與冶金工作者要求匹配的授拌模式。 再者,對於瞭解連續鑄造期間之金屬固化機構的不斷 進步已明確顯示液態金屬的循環運動對於最終固化產品的 整體品質(即内部健全、表面清潔度或沒有失雜物、固化 結構等)扮演的重要角色= 就這一點而言,在連續鑄造期間施加至熔融金屬的運 動可概要分為兩種,取決於吾人所考慮的是鑄模或是其下IX. DESCRIPTION OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to continuous casting of metals, particularly steel. In particular, electromagnetic stirring during casting of flat products (i.e., elongated sections), to a more precise degree, is a special distribution of the flow in the metal liquid pool using an applied magnetic field. [Prior Art] Please note that the "slim section product" is a metallurgical product with a width at least twice the thickness, especially a small slab of slab. It appeared in the field of continuous cast steel in the early seventies, and electromagnetic stirring has quickly established itself as an almost essential tool for controlling the flow in the liquid pool during solidification. It is remembered that the most commonly used principle is the Mhd (Magnetic Fluid Dynamics) principle, which is well known in the art, which utilizes the movement of a multiphase sensor, or, in general, several multiphase sensors placed adjacent to the casting (rotation) Or the magnetic field drives the liquid metal with its displacement. These inductors, suitably located at the metallurgical height of the casting machine, are supplied with current at an adjustable frequency, thereby providing a variety of mixing modes that can be matched to the requirements of the metallurgist. Furthermore, it is clear that the continuous advancement of metal-curing mechanisms during continuous casting has shown that the cyclic motion of liquid metal plays a role in the overall quality of the final cured product (ie, internal soundness, surface cleanliness or no debris, solidified structure, etc.). Important role = In this regard, the motion applied to the molten metal during continuous casting can be broadly divided into two types, depending on whether the mold is considered or underneath
