The complex design of the duo cold-mill, especially the pass. Aiming at this challenge, a parametric mathematical model of the pass is established in the present study. The cold rolling process of 50 pairs of tubes with reasonable actual rolling quality is simulated to obtain the change law of the rolling force. In the trial rolling test, it is found …

The pressure die (also called a pressure slide) supports the outside radius during bending. The pressure die can be stationary; it can follow the workpiece, sliding on rollers at the same rate the workpiece is being drawn into the bend; or it can be "boosted," pushed with hydraulics or (more common today) electrical servomotors, further …

The primary job of the fin section on any tube or pipe mill is to prepare the edges of the strip (parallel) for welding, and set the body of the tube. The only way this will take place, is if we properly set (work) each and every driven and side pass station in the fin section as per the tooling design and set up chart.

Adding to the complexity, this flow rate ideally should be 25 to 30 PSI at the point of dispensing because pressure is lost within each plumbing component. The mill reservoir should be placed close to the mill and use larger-diameter pipe over shorter distances to provide the least change in coolant pressure from the pump to the mill.
