2A12铝合金厚壁管材生产工艺研究

摘要

The key technologies such as extrusion, roll straightening and tension were grasped by the development of the large-scale 2A12 aluminum alloy tube withФ258×9.5mm, which have positive significance for development and production of hard alloy tube.%通过对φ258×9.5mm大规格2A12合金管材的研制，进一步掌握了生产该合金管材的挤压、辊矫、张力拉伸等关键技术，为今后开发硬合金管材积累了生产经验。
