介绍了目前全球大型铝挤压机的装备情况，国内高速铁路及地铁的建设及其车辆制造规划，以及大型铝型材的市场前景。在全球拥有的５０多台大型铝挤压机中我国有８台，可满足我国２０２５年以前国内市场对大型铝型材的需求。在近２５年内再建设新的大型铝挤压生产线似应慎之又慎。
The current global large-scale aluminum extrusion equipment, the introduction of domestic high-speed rail and subway construction and vehicle manufacturing planning, as well as large aluminum market prospects. In the world with more than 50 large-scale aluminum extrusion machine in China has eight units to meet our domestic demand for large-scale aluminum profiles before 2025. In the past 25 years and then build a new large-scale aluminum extrusion production line should be cautious.
