西南铝120MN全浮动张力拉伸机组

摘要

To meet the requirement of high-intensity material for Chinese "great airplane" item, China National Heavy Machinery Research Institute Co. , Ltd. designed and manufactured a biggest stretcher-120Mn full-floating tension stretcher for Xinan Aluminum Co. , Ltd. The equipment configuration, process flow, main technical parameters and key technology are introduced in this paper. The actual operation indicates that the techi-nology parameters of the stretcher are reasonable and the capability can meet the design requirement. The comprehensive quality of the equipment has reached the international level.%为满足国家“大飞机”项目高强度的材料要求,中国重型机械研究院股份公司(简称中重院)为西南铝业(集团)有限责任公司研制了国内最大吨位矫直机——120 MN全浮动张力拉伸机,本文主要介绍了该机组的设备组成及工艺流程,主要技术参数和采用的一些关键技术.通过现场使用情况表明,该设备技术参数合理,性能满足设计技术要求,设备运行稳定可靠,产品综合质量达到国际领先水平.
