摘　　要：介绍了高速列车用空腔薄壁型材的生产难点,并针对型材挤压生产时挤压抗力大,严重影响模具质量和生产效率等问题,选取典型断面开展研究,从合金成分设计、铸棒质量以及挤压模具结构三个方面降低型材的挤压抗力,指出了降低挤压抗力的有效方法。The production difficulty of thin walled cavity profiles of the high-speed train was introduced in the paper. The quality and production efficiency of mold had been affected due to large extrusion resistance during extruding profiles. Typical section is selected to research, from the alloy composition design, casting quality and extrusion die structure, to reduce the extrusion resistance,and the effective method to reduce the extrusion resistance is pointed out.

关 键 词：6005A合金 挤压抗力 高速列车
