| 摘 要： | 基于三段矫直曲线应变速率的假设,通过计算三段矫直曲线的精确解,验证了使用小变形条件的正确性;考虑高温铸坯蠕变性能,对铸坯的力学行为进行了分析,得出了使用三段矫直曲线方法,铸坯应变速率、应力及应变在矫直区内变化较为平缓,可有效避免铸坯内裂纹的形成;使用本文三段矫直曲线精确解,调整辊列位置,可进行连铸机的在线技术改造。

| Abstract: | Based on the hypotheses of three piece straightening curve.It is verified that the method for using little deformation condition was true with accurate solution of three piece straightening curve.The mechanics behavior of slab was analyzed in regard to the creep properties of high temperature slab.The results show that the strain, the strain velocity and the stress varied so smoothly that the inner crack was prevented.Technical renovation is carried on by adjusting the displacement of rolls and by using the accurate solution of three piece straightening curve. |
