针对宝钢2050热轧生产线上新型号支承辊,采用有限元仿真技术,以有限元模拟软件ABAQUS为平台,运用热-力耦合方法动态模拟各道次轧制过程,分析轧制过程中该支承辊的工作状态。分析认为支承辊辊身与工作辊辊身接触部位、支承辊辊颈与轴承接触部位及支承辊辊颈与辊身连接的部位是可能失效的主要部位,校核后结果表明,该支承辊在工作时是安全的。经过实验验证,仿真结果与实际生产数据比较吻合,仿真结果准确可靠。
Aiming at the new type of backup roll in Baosteel 2050 hot rolling production line, finite element simulation technology and finite element simulation software ABAQUS were used as a platform to dynamically simulate each pass rolling process by using thermo-mechanical coupling method. During the rolling process, Work status. It is analyzed that the contact area between the support roller body and the work roll body, the contact area between the support roll neck and the bearing and the connection part between the support roll neck and the roll body are the main parts that may fail. After checking, the results show that the support roll Work is safe. After experimental verification, the simulation results are in good agreement with the actual production data, and the simulation results are accurate and reliable.
