摘要: 通过ANSYS软件模拟了200 mm×1600 mm不锈钢板坯连铸轻压下过程扇形段铸坯的变形,得出1~#到11~#扇形段辊缝的动态补偿量0.2~1.0 mm。生产应用表明,拉速0.7 m/min和0.9 m/min,压下速率0.8~1.4mm/m,总压下量1.30~4.56 mm,铸坯中心偏析均有改善,铸坯厚度与设定值之差≤0.5 mm;拉速为0.7 m/min时,未采用动态轻压下时,C、S中心偏析指数为1.30,当压下速率为1.2 mm/m,压下区间固相率20%~50%时,C、S中心偏析指数降至1.05。

Abstract: Deformation of slab at segment during dynamic soft reduction of casting 200 mm x 1 600 mm stainless steel slab has been simulated by soft ware ANSYS. It is obtained that the effective compensation of roll gap at No.l to No.11 of segment is 0.2 ~ 1.0 mm. Production application results show that with casting speed 0.7 m/min and 0. 9 m/min, dynamic soft reduction rate 0.8 ~ 1.4 mm/m, total reduction 1.30 〜4.56 mm, the center segregation of slab all improves and the error of thickness of slab between measured and given value is less than 0. 5 mm; at casting speed 0.7 m/min, as without using dynamic soft reduction the center segregation index of C and S is 1. 3, while with dynamic soft reduction rate 1. 2 mm/m, solidification rate at reduction zone is 20% 〜50% , the center segregation index of C and S decreases to 1.05.
