包钢要从苏联引进年产25万吨钢轨油中整体淬火生产线。为作好引进的技术准备工作,论证了钢轨热处理强化的远景,淬火轨的经济效益。指出了筹建热处理生产线是加速铁路运输发展急需采取的对策之一。作者根据掌握的苏联各生产厂淬火轨试验、生产方面的资料,论述了整体油中淬火工艺的优点,同时也指出了该工艺存在的、有些是不可克服的缺点,供同志们参考。最后,根据世界淬火钢轨发展趋势及包钢进行的、经冶全部鉴定的“钢轨整体加热全长淬火新工艺”的经验,对包钢的钢轨热处理生产线提出了初步设想。
Baotou Steel imports from the Soviet Union with an annual output of 250,000 tons of rail oil in the overall quenching production line. In order to make good preparations for the introduction of technology, this paper demonstrates the prospect of rail heat treatment strengthening and the economic benefits of quenching rail. It is pointed out that the preparation and construction of heat treatment production line is one of the measures urgently needed to accelerate the development of railway transportation. Based on the master quenching rail test and production data from various production plants in the Soviet Union, the author discusses the advantages of the quenching process in the whole oil, and also points out some shortcomings that exist in the process, some of which can not be overcome, for the reference of comrades. Finally, based on the development trend of the world’s hardened steel rails and the experience of “all-in-one quenching new technology of whole rail heating”, which was carried out by Baotou Steel, the tentative plan was put forward for the rail heat treatment production line of Baotou Steel.
