摘要 本文针对热轧厂SP侧压调宽后出现板形不良而造成热轧成材率下降的问题，提出采用新型双斜面侧压模块以改善SP侧压后的板坯形状、降低板坯的尾部翘曲。有限元数值模拟与实验的研究结果表明：采用新型双斜面模块调宽后，板坯中部的“狗骨”峰值有较大程度的降低，其 “狗骨”的最大高度值小于目前热轧厂普遍使用的单斜面模块，而宽度方向上中心部位的厚度大于单斜面模块；同时，双斜面模块的调宽效率高于单斜面模块；相同变形条件下，经单斜面模块侧压后的板坯尾部翘曲程度大，双斜面模块能够明显减小SP侧压后的板坯尾部翘曲，采用双斜面模块可以改善板坯SP侧压后的板形。
Abstract ：To improve the profile of the slab after SP and increase the production efficiency, a new SP tow-step anvil is put forward in this paper. The experimental and FEM results show that, compared with the old anvil, the peak of the “dog bone” reduces and the thick of the middle slab increases after SP when applying the new tow-step anvil. Meanwhile, the slab width adjustment efficiency of the tow-step anvil increases. Under the same deformation conditions, the slab warp after SP reduces obviously.
