Description

Mill Roller

Mill Roller is the core forming components of welded pipe production lines (such as straight seam welded pipe and spiral welded pipe production lines). Through the continuous rolling of multiple sets of rolls, flat plates or steel strips are gradually bent and shaped, ultimately forming steel pipe billets that meet the specifications, laying the foundation for subsequent welding processes.

Core function and working principle

1. Strip Steel shaping: Through the coordinated action of multiple passes and groups of rolls, the flat strip steel is gradually bent from its initial state into tubular profiles such as "U" and "O" shapes, ensuring the precise cross-sectional dimensions of the tube blank.
2. Control accuracy: The groove type, size and surface accuracy of the rolls directly determine the diameter, roundness and wall thickness uniformity of the pipe blank, which is the key to ensuring the final size qualification of the welded pipe.
3. Stable conveying: During the rolling process, the rolls simultaneously drive the steel strip to continuously and smoothly convey forward, ensuring a smooth production flow and preventing the steel strip from deviating or getting stuck.
