  1. This segregation behavior of sn accords with the mechanism of non - equilibrium segregation. it can be obtained through the theoretical calculations that the critical time of sn non - equilibrium segregation is 124 seconds at 750 and the critical cooling rate is 8 / s when cooling from 1320. it is suggested that controlling the cooling rate during continuous casting to avoid the critical cooling rate ( 8 / s ) and avoiding high stress near the trough temperature ( 750 ) may control the form

    通過研究殘留元素sn的偏聚機制及其對o . 15wt . % c鋼熱塑性的影響,對試驗鋼進行脆性預測:建議在該鋼的連鑄過程中彎道矯直溫度盡量避開塑性谷底溫度750 ,二冷區的冷速盡量避開臨界冷卻速率8 / s ,從而可以減少該低碳鋼連鑄坯表面裂紋和橫向裂紋,提高其成材率。
