本篇文章是在攀钢轨梁厂和攀枝花钢铁研究院75公斤/米重轨轨端帽形淬火试验工作的基础上提出了三个比较重要的问题,即淬火层深度如何提高的问题;白线层问题;纵向硬度的所谓翘尾问题。根据淬火工艺试验实践对这三个问题提出了一些看法,提供有关厂家和科研单位的同行交流,探讨。 This article is based on the test of 75kg / m heavy rail rail end cap quenching test at Panzhihua Iron and Steel Co., Ltd. and Panzhihua Iron and Steel Research Institute, and puts forward three more important questions: how to increase the depth of quench layer; Line layer problems; the so-called end-to-end warp problem. According to the practice of quenching test put forward some views on these three issues to provide peer-related manufacturers and research units exchange, discussion.
