摘　　要：轨道车辆用的铝材主要通过挤压方法生产。车体结构用的挤压铝材是大型材,中小型材用于车体内部装修。前者用量占车体铝材用量的80%以上。本文分两部分发表,第一部分概述了车体型材的生产工艺流程、铝结构车体的设计要求、车体大型材的规格类型。介绍了大型材的制坯、挤压、热处理等工序。Extruded aluminum takes a major part of aluminum materials for rail vehicle. Among extruded aluminum for car body, small and medium profiles are used as internal decoration and large profiles as structure,which account for more than 80% of the aluminum for car body. As the first part of the paper （ two parts）, it demonstrates the process flow of pro-files for car body, the design requirements for car body with aluminum structure and the types of large profiles for car body. Meanwhile, the processes of blanking, extrusion and heat treatment are also introduced for large profiles.
