摘要
钢轨焊接接头的品质关系到铁路行车安全,对钢轨焊接接头进行正火处理是提高焊接接头性能的重要手段。目前,现场钢轨移动式气压正火设备控制方式比较落后,自动化程度低,人为因素影响多,正火品质波动大。研究钢轨火焰正火品质控制关键技术,尽早研制开发出适用于现场正火的自动控制设备有着十分重要的意义。为此,介绍了钢轨焊接接头的数控正火系统。
The quality of rail welding joints is related to the safety of railways transportation.The rail welded joints for normalizing treatment is an important means to improve the performance of welding joints.At present,the rail mobile normalizing equipment control method is quite backward,the degree of automation is low,the human factor affects the normalizing quality greatly.Therefore,this paper makes a study of the rail normalizing quality control key technologies,develops automatic control equipment in the field of normalizing as soon as possible and introduces NC normalizing system of rail welding joints.
