摘要
概述了我国冷轧管机各设计制造企业的研制现状和主要机型,着重介绍了LG型二辊冷轧管机和LD型多辊冷轧管机的孔型设计方法,对我国冷轧管机未来的发展方向进行了展望,认为高速、长行程,不停机连续上料,生产过程全自动化控制的冷轧管机是发展的大方向。指出我国的冷轧管机正处在更新换代的最佳时机,应把握住时机将我国冷轧管设备的水平推向一个新的高度。
Summarized in the assay are the current R ＆ D situations concerning design and manufacture of the tube cold-rolling mill by relevant domestic companies, and the major types of the mill, focusing on the pass design methods for the LG 2-roll cold-rolling mill and the LD multi-roll cold-rolling mill. The development trend of the cold-rolling pipe mill is forecast. And it is regarded that the cold-rolling pipe mill featuring hi-speed, long travel and continuous charging function and full automatic control of the manufacturing process will be the main development orientation of the cold-rolling pipe mill. Moreover, it is emphasized that the domestic tube cold-rolling field is right now facing the best opportunity for upgrading, and should grasp it to promote the domestic tube cold-rolling equipment technology to a much higher level.
