本试验以唐钢立式连铸机浇注的16Mn方坯(140×140mm)为对象,采用了结晶器N_2气保护下连续喂入混合稀土金属丝的工艺,研究了稀土对铸坯质量和钢材性能的影响。在[RE/[S]=2～3的范围内,铸坯中RE和S的分布均匀、等轴晶率增加、柱状晶区枝晶的
In this experiment, the 16Mn billet (140 × 140mm) cast by Tangshan vertical continuous caster was used as the object, and the technology of continuously feeding mixed rare earth wire under the protection of mold N_2 gas was studied. The effects of rare earth on slab quality and steel properties influences. In the range of [RE / [S] = 2 ~ 3, the distribution of RE and S in the slab is uniform and the equiaxed grain rate increases. The dendritic
