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

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.
