Therefore, due to the fact that the (111) pole density in the subsurface of decarburized bands still have a higher intensity, adding Mo into Hi-B steels could lower the slab reheating temperature.

本文采用X射线极密度和取向分布函数方法，证明含Mo Hi-B钢采用1310℃低温铸坯加热时，其热轧板表层织构特征与不含Mo并在1380℃高温铸坯加热时相似，为典型的剪切形变织构，两者的热轧板与脱碳板表层织构特征也极为相似，而含Mo Hi-B钢在1380℃铸坯加热时却没有以上这些相似性。
