Abstract

PURPOSE:To reduce the negative segregation in an ingot and the segregation in the central part, and reduce strain aging embrittleness during working by subjecting residual molten steel to electromagnetic induction stirring in the magnetic field induced by the AC of specific frequencies and specific magnetic flux densities. CONSTITUTION:The molten steel having beforehand been subjected to cleaning treatment in a converter or ladle is charged together with flux with an immersion nozzle into a mold, and it is continuously drawn out in the downward direction of the mold under non-oxidative casting. Within the range of approximately <=1/2 of the short side of the ingot with respect to the ingot of <=200mm. loop short diameter of the residual molten steel in the ingot at the end period where the molten steel solidified as an ingot, and within the range of approximately <=100cm. with respect to the ingot of >=200mm., the residual molten steel is subjected forcibly to electromagnetic induction stirring by the electromagnetic device provided to the outside circumference of the drawn out ingot by the magnetic field induced by applying the AC of frequency f=1.5-10Hz and 895Xe<-0.20f=G<=2137Xe<-0.20f> magnetic flux density G on the surface of the ingot. Hence, the steel material of good quality with less central segregation is obtained.
