摘　　要：介绍了我国钢轨和大H型钢生产技术与装备的发展情况,主要包括钢轨用钢的研究和发展,钢轨钢的冶炼和连铸技术,钢轨万能轧制工艺、精整和检测装备与技术,以及大H型钢的生产工艺布置和近终形连铸异形坯、X—H轧制法等技术。并指出,生产400mm系列和更大规格的U型、直线型、Z型、H型钢板桩是我国大型型钢生产面临的重大技术难题。The development of production processes and equipment of rail and heavy H-beam in China were introduced. The main contents were the studies and progress of rail steels, its steelmaking and casting proeesses, universal rolling technology , finishing process and detection equipment and techniques, and applying near net shape casting billet and X-H technology for heavy H-beam. At last, the authors pointed out there are diffi- culties in China for 400mm and more large gauges U, Z, H and line section piling bar.
