するという問題があった。In a casting method using a continuous casting machine, it is common to supply molten steel from a tundish into a continuous casting mold directly or through a submerged nozzle. However, in the conventional continuous casting method, even if the discharge hole angle of the submerged nozzle is changed, the molten steel flow injected into the continuous casting mold deeply penetrates into the unsolidified casting area, resulting in the slag accompanying it. Similarly, air bubbles also penetrate deeply and are trapped in the solidified shell, and the difference in specific gravity between them and the molten steel prevents them from surfacing and escaping to improve the surface of the molten steel, resulting in a reduction in product quality. Ta.

As disclosed in Japanese Patent Application No. 856, a technique has been proposed in which the flow of molten steel in a continuous casting mold is decelerated by a static magnetic field and dispersed and stirred. As shown in FIG. 1, an excitation means 2 consisting of a DC exciting electromagnet bundle or an electromagnet having a pair of magnetic poles is placed outside the continuous casting mold 1 at a position immediately after the molten steel flows into the continuous casting mold 1. The flow of the molten steel 5 is decelerated by applying a static magnetic field 6 to the molten steel 5 flowing into the continuous casting mold 1 from each injection port of the immersion nozzle 8 in a direction that intersects with the flow direction of the molten steel 5. This results in an upward dispersion flow. According to this technology, melt! a5
The generation of an upwardly dispersed flow effectively prevents the entrainment of slag and air bubbles, and also reduces the depth of penetration of the molten steel flow into the unsolidified casting area based on the deceleration of the flow, and prevents its solidification. By preventing collision with shell 8,
Obstruction of floating and escape of slag and air bubbles onto the surface of the molten steel and their capture by the solidified shell B are respectively prevented.

内部への進入深さが、第2図に示すように、従来技術の
ほぼ半分にはなるものの、それでもなお2iの進入深さ

に防止することができない問題があった。However, according to this technique, the penetration depth of the molten steel flow into the unsolidified casting region is approximately half that of the conventional technology, as shown in FIG. 2, but the penetration depth is still 2i. Therefore, even with this technique, there was a problem that deterioration in product quality could not be sufficiently prevented.

。The present invention advantageously solves this problem by applying a static magnetic field to the flow of molten steel injected into the continuous casting mold in a direction intersecting the flow direction of the molten steel. The continuous casting strand is forced to decelerate to disperse stirring, and the remaining flow of the molten steel, which escapes the force and flows downward along the wall surface of the continuous casting mold, is caused to flow in a continuous casting strand directly below the continuous casting mold in a direction that intersects with this. The present invention provides a method for stirring poured molten steel in continuous casting, which comprises a combination of applying a static magnetic field to further slow down the flow and strengthening it by dispersion stirring, and a device directly used for carrying out the method. be.

硝実ならしめるものである。The present invention applies a static magnetic field to the poured molten steel flow in a continuous casting mold, decelerates the flow, and disperses and stirs it in the L direction, thereby preventing the entrainment of slag and air bubbles.
In addition, by applying a static magnetic field directly under the continuous casting mold to the residual flow of molten steel that is not dispersed and stirred, this residual flow is also decelerated, and by dispersing and stirring, the unsolidified steel is This effectively prevents slag and air bubbles from entering the casting area, thereby making it easier to prevent slag and air bubbles from floating and escaping.
以下に本発明を図示例に基づいて説明する。The present invention will be explained below based on illustrated examples.

Two sets of excitation means 14 made of DC excitation electromagnets or permanent magnets having a pair of magnetic poles are arranged in the vicinity of the condition injection position from 2 to there so that a static magnetic field 14a can be applied in the thickness direction of the continuous casting mold 11. Further, an excitation means 17 similar to that described above having a pair of magnetic poles sandwiching the casting strand 15 is disposed directly below the continuous casting mold 11 so as to directly oppose the solidified shell 16 of the casting strand 15.

A static magnetic field 14a acts on the molten steel flow go injected into the continuous casting mold 11 in a direction perpendicular to the flow direction near the inflow position, so that the flow is caused by the static magnetic field 14.
Depending on the direction of action of a, the speed is reduced in accordance with Fleming's law to force dispersion and stirring. Therefore, an upward dispersion flow 21 is generated in the molten steel flow 20, effectively preventing slag and bubbles from being drawn into the unsolidified casting region, and facilitating their floating and escape.

のとなる。On the other hand, the residual flow of the melt that is decelerated but not forced to undergo the above-mentioned dispersion stirring is caused by the excitation means 17 acting in the width direction of the cast strand 16 in the direct direction of the continuous casting mold 11, intersecting with the flow direction. The static magnetic field 17a from the flow rate is substantially stopped by the rml kJJ force proportional to the square of the flow velocity, and the dispersion agitation is enhanced, resulting in a separate upward dispersion flow 22. Therefore, the entrainment of slag and bubbles is more effectively prevented here, and their escape from the surface based on the difference in specific gravity is further ensured by piggybacking on the upward dispersion flow z2 and substantially stopping the residual flow.
