“错位”式二辊斜轧管机喂入角的讨论

Discussion on Feed Angle of "Skewed" Type 2-roll Rotary Rolling Pipe Mill

简述了喂入角在斜轧无缝钢管生产中的意义,提出了"错位"式二辊斜轧管机的设想,建议以轧辊/轧制线平面为基准来确定喂入角。在此基础上,分析了二辊式斜轧管机轧辊布置方式不同时,轧辊轴线在相关平面的投影关系及其对轧件运动的影响。

Briefed is the role as feed angle plays in seamless steel tube rotary rolling process. The concept of the ＂skewed＂ 2-roll rotary-rolling pipe mill is proposed. It is suggested to determine the feed angle with the roll/ rolling line plane＇as the reference. With such given conditions, the co-authors analyze the projection of the roll axis on relevant plane, and its influence on the movement of the rolled piece with different roll arrangement types.
