Claims (2)

주조슬랩 및 불룸의 제조시, 인발되는 주조슬랩 및 불룸의 비응고 용강에 전자교반력을 가하는 방법에 있어서, 비응고부분의 두께가 주조슬랩 및 불룸의 두께방향에서 관측된 두께의 45% 내지 15%되는 부분에 위치시키고, 비응고 및 응고부분사이의 계면에서의 자속밀도(단위 : 가우스)와 교반시간[전자교반기의 교반유효거리(mm)와 주조속도(m/min)의 비율로 정의되며 단위 : min임]의 곱의 값이 전자교반기가 위치된 것으로부터 인발부로 연장된 부분에 있는 비응고용강의 전체체적(단위 : ㎥)의 ㎥당 1600gauss·min 또는 그 이상이 되도록 비응고용강에 주조방향으로 교반을 가하는 것을 특징으로 하는 연속주조에 있어서 용강의 전자교반방법.In the manufacture of casting slabs and blooms, in the method of applying an electromagnetic stirring force to the casting slabs and the non-solidified molten steel of the blooms, the thickness of the non-solidified portion is 45% to 15% of the thickness observed in the thickness direction of the casting slabs and the blooms. It is located at the part which is%, and it is defined as the ratio of magnetic flux density (unit: Gauss) and stirring time [the stirring effective distance (mm) of the stirrer and the casting speed (m / min) at the interface between the non-solidification and the solidification part. Unit: min] is cast in non-solidified steel so that the value of the product is 1600gauss · min or more per m3 of the total volume (unit: m3) of the non-solidified steel in the portion extending from the place where the electronic stirrer is located. The stirring method of the molten steel in continuous casting, characterized in that the stirring in the direction. 청구범위 제 1 항에 있어서, 전자교반기를 주조슬켑 및 불룸의 두째방향에서 볼때 비응고부분의 두께의 35% 내지 20% 범위인 인발부사이에 위치시키는 것을 특징으로 하는 연속주조에 있어서 용강의 전자교반방법.8. The electrostirring of molten steel in continuous casting as set forth in claim 1, wherein the electrostirrer is placed between the draw portions in the range of 35% to 20% of the thickness of the non-solidified portion as seen in the second direction of the casting slab and the bloom. Way. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
