文摘 短应力线轧机是钢铁制造行业大规模使用的机电一体化设备。我国是世界上废旧轧机保有量最大的国家,大部分轧机都因在高温、高湿、微动磨损恶劣环境下服役而导致轧机系统精度下降,失效报废。同时,废旧报废状态的轧机占用企业大量的存储和场地资源,闲置轧机的自然腐蚀将会造成严重的环境污染。激光再制造技术是一种新型高效绿色的轧机修复再制造技术,本文总结了短应力线轧机主要失效方式和激光再制造技术的应用概况。从轧机工况分析、失效机理、材料设计等方面详细评述了短应力线轧机激光再制造存在的主要问题,以及针对这些问题开展的国内外相关研究工作和最新发展动态。在此基础上,指出设计轧机激光再制造专用材料、研发激光再制造过程的实时监测和反馈系统、建立激光再制造后轧机服役性能评价标准、拓展轧机整机激光再制造领域将是未来的主要发展方向。
其他语种文摘 The short-stress-path rolling mill is a mechatronics equipment which is widely used in the steel manufacturing industry.China has the largest number of used rolling mills in the world.Most of the rolling mills are served under the harsh environment of high temperature,high humidity and fretting wear,which leads to the decrease of rolling mill system accuracy and failure scrap.At the same time,the rolling mills in the scrapped state occupy a large amount of storage spaces and site resources of the factories.Furthermore,the natural corrosion of the idle rolling mill will cause serious environmental pollution.Laser remanufacturing is a new type of technology for high-efficiency green rolling mill repairing and remanufacturing.The main failure modes of short-stress-path rolling mills and the application of laser remanufacturing technology on short-stress-path rolling mills were summarized in this paper.From the aspects of mill condition analysis,failure mechanism and material design,the main problems in laser remanufacturing of short-stress-path rolling mill and related research work and latest developments on these issues were reviewed.On this basis,it was pointed out that the main development direction in the future is to design special materials for laser remanufacturing of rolling mill,develop real-time monitoring and feedback system for laser remanufacturing process,and establish evaluation standards for service performance of rolling mill after laser remanufacturing,and to expand the field of laser remanufacturing of rolling mill.
