Continuous rolling process of straight seam steel pipe
Straight seam steel pipe continuous rolling process, the continuous rolling process is used in the continuous rlling and diameter reduction process of the steel pipe. Continuous steel pipe rolling is a process in which a steel pipe and a core rod move together in multiple stands. The deformation and movement of the steel pipe are simultaneously affected by the roll and the core rod.
The mandrel can be free-floating, that is, it is driven by metal to move forward; it can also be limited, that is, giving the mandrel a speed of movement to limit its free movement. During the movement, the mandrel, roll and steel pipe are connected into a whole, and any one of the changes in the link will cause the state of the entire system to change. The theory of continuous rolling is to study the relationship between them.
