摘要

阐述了三辊全浮连轧管工艺的技术优势,并分析说明了"竹节"控制原理和实施方案。以国内经多年生产实践并运行良好的某Φ140mm二辊全浮连轧管机组为基础,以淘汰落后产能为目标,开发出新型三辊全浮连轧管机。从孔型设计、变形分配、力能参数3个方面建立数学模型,并进行实例分析。结合实例,建立了有限元计算模型,采用有限元分析方法对三辊全浮连轧管机组的轧制全过程进行计算机模拟,为三辊全浮芯棒连轧管机的实际生产提供技术参考。
        The technical advantages of 3-roll full float mandrel were expounded,and the"bamboo"control principle and implementation scheme were introduced.Based on a Φ140mm 2-roll full float mandrel pipe mill in China which run a good production over years,a new 3-roll full float mandrel pipe mill was developed to close down backward production capacity as a goal.The mathematical models of the roll pass were designed,the distribution of deformation and mechanical energy parameters were established,and the analysis example was introduced.Combined with example,the finite element model was established,and the computer simulation for the whole rolling process was carried out.It would provide technical reference for actual production of the 3-roll full float mill.
