Abstract

ABSTRACT Application of vibration impact at the outer arc side of a billet with a central linear liquid fraction of 25% -35% at 9.5 m from the meniscus. The results show that the impact vibration with low frequency and high impact energy can not only reduce the central porosity degree of the billet from 1.532 to 1.169, but also compact the liquid core, improve the central porosity and promote the heterogeneous nucleation of the molten pool. High frequency and low impact energy can not only increase the proportion of mixed crystal zone by about 8 %, but also reduce the central carbon segregation index from 1.08 to 1.04. Meanwhile, the two kinds of impact vibrations increase the area ratio of the central carbon segregation index in the range of 0.95-1.05 from 56.32% to 70.26% and 80.17%, respectively, and uniform the central carbon distribution of the billet.

凝固端部冲击振动对连铸坯内部质量的影响
振动冲击在距离弯液面9.5米处中心线性液体分数为25%-35%的钢坯外弧侧的应用。结果表明,低频高冲击能量的冲击振动不仅可以将坯料的中心孔隙率从1.532降低到1.169,而且可以压实液芯,提高中心孔隙率,促进熔池的非均匀形核。高频率和低冲击能量不仅可以使混晶区的比例增加约8%,而且可以将中心碳偏析指数从1.08降低到1.04。同时,两种冲击振动使0.95-1.05范围内的中心碳偏析指数的面积比分别从56.32%提高到70.26%和80.17%,使坯料的中心碳分布均匀。
