Basics of the Rod Rolling Mill Process
Rod mills, which also often double as bar mills, can turn out huge amounts of metal fashioned into rods of various thickness. These rods are cooled and sliced into desired lengths and are manufactured according to specifications needed for particular applications.

Function
-
Materials are rolled for many different reasons, with formations of rods from these materials being one of the most common resulting products. This causes a lasting change to the material as it is pressed between two large cylindrical metal rollers. The resulting flattened material can then be formed into many different shapes, including rods, for different jobs.
Considerations
-
When the flattened metal is being conveyed through the milling process, clearance is an important consideration. Clearance allowance must be precise to let the exact thickness pass through the machine in order to get the correct end product. Another consideration is proper alignment of the roll center lines. This ensures that the proper width of flattened metal is being milled, again to achieve the desired final rod.

History
-
Mills used as rollers have been around since at least 1590. They began as small, simple machines that were powered by flowing water. Wider metal sheets began appearing around 1720 when inventor John Hanbury perfected rollers for the production of tinplate and Henry Court introduced rollers in 1784 that could press grooved rolls that could be made into round sectional pieces such as rods.
