The Effect of Electromagnetic Stirring on Steel Strand Quality

Application experiments have been done to research the strand quality of high carbon steel 65Mn under the condition of electromagnetic stirring. The experimental results show that the effect of electromagnetic stirring with stirring rollers in side-side disposition mode is better than that in face-face disposition mode. The effect of electromagnetic stirring is also increased with the increasing of current intensity, and the continuous stirring is better than alternating stirring. Thus, conclusion could be arrived that the strand inner quality is improved obviously by the adoption of electromagnetic stirring due to 32% increase of equiaxed zone ratio in the strand and the decrease from B0.5 to C1.0 of the center segregation grade.
