Electronic stirring method at the end of solidification during continuous casting of lectures

摘要

The present invention relates to a method for setting the most effective stirring time to reduce the center segregation when the magnetic stirring is applied at the end of the solidification to reduce the center segregation during the continuous casting process of the bloom and billet of molten steel, the flow limit high as C% increases Based on the fact that the agitation thickness will decrease with increasing C%, based on the fact that the penetration depth of the residual molten steel increases and the solidification time increases in the solid-liquid coexistence region at the phase rate, In the case of 0.6≤C% ≤1.1, do = 156 ~ 166-130 ℃%, and in the case of bilette do = 68 ~ 78-26 ℃% within the range of 0.2≤C% ≤0.8.
