The macrosegregation is formed in central area of the billet resulted from the continuous enrichment of solute during solidification process.
随凝固的进行,液相中的溶质不断富集,最终在铸坯的中心区域形成宏观偏析。
In order to enhance the uniformity of slab solidification structure and reduce macrosegregation, a self consumption of vibration excitation of nuclear technology in liquid steel was proposed.
