【摘要】 通过对 LD—60型冷轧管机的现场测试以及实验数据分析,说明了 LD 型冷轧管机有它自己的变形特点。轧制过程中变形量沿宏观变形区长度上的分配,影响金属在变形工作锥上的硬化过程、轧制力参数以及变形工具的使用寿命。本文在实验研究的基础上,提出了在 LD 型冷轧管机变形区上力参数的合理分布原则,并据此提出相对减壁量沿宏观变形区长度上的分配原则。更多还原

【Abstract】 Measurements and experimental investigations in the LD-60 type cold pilgrim mill showed that deformation of this mill has it’s own characteristics.The distribution of the deformation over the reduction zone has influence on the working har-dening of metal,the rolling pressure and service life of the deformation tools.In this paper,based on experimental investigations,a reasonable distribution principle of thepressure over the reduction zone,is proposed and on this basis,a distribution principle of the re-lative wall reduction over the reduction zone is suggested too.更多还原
