[*]浅析重轨轧制工艺
对重轨生产而言，传统意义上的压缩比已经不能反映轨头，轨腰及轨底的实际变形规律。经过严格控制的连铸坯，其在组织结构上仍无法与初轧坯(经过切头、切尾和大变形)相比。重轨轧制工艺应做相应彻底改进，重轨性能在钢质得到保证的情况下，主要依赖于轧制工艺对组织进行改善，与初轧坯相比，其原有的轧制工艺从以变形为主转到以承担形状控制和组织控制双重任务为主。
The heavy rail production, the traditional sense of the compression ratio can not reflect the rail, railrail bottom deformation. Through strict control of continuous casting slab, the organizational structureno bloom (after cutting head, taillarge deformation) compared. Heavy rail rolling technology should make the corresponding complete improvement of heavy rail steel, performance in which case, rely mainly on organization improvements in rolling process, compared with the bloom, its original rolling process from deformation to assume the shape controlorganization control of dual task.
