摘要
特宽空心壁板型材是高速列车用高效经济的断面型材 ,文中介绍了模具设计、挤压工艺 ,尤其是横向平直度控制的技术关键是控制金属质点的均速流动和随机淬火温度 5 2 0℃ ,挤压速度 2～ 3m/ min的控制 ,可获得高性能合格的特宽空心型材。
Super-wide hollow wall panel profiles are the high efficiency and economic sections for high speed train. Die design and extrusion process are introduced in the paper. Especially,the technical key for controlling transverse flatness is to control the uniform flow of metal.On-line quenching temperature is 520℃,and extrusion speed is within 2～3m/min.Such high-propety and qualified super-wide hollow profiles can be obtained.
