Jun 25, 2014· Some rolling mills are simply equipped with a smooth, flat roller while others have a combination roller. The combination roller offers a section of flat surface and a section with wire grooves. The wire grooves do not roll perfectly round wire, though; for that, you would need a full round rolling mill. The wire grooves roll mainly square wire....
