In general, "rolling" is a process that uses a pair of rolls to form materials. There are two rolling techniques, hotrolling and coldrollforming based on the temperature of the metal being used. If the temperature is above the crystallization temperature of metal, the process is called hotrolling; otherwise it is called coldrolling.

Nov 06, 2017· In the classic sense, a tube mill is a kind of welded roll form system; however, not every welded roll form system is a tube mill. Tube mills are welded roll form systems that have been finetuned to run a specific diameter range, typically at fast speeds (see Figure 1). Diameter range is mentioned because a tube mill welds a round product.
Jan 11, 2005· Roll Forming a Tube. Now let''s roll form the same 2in.diameter tube with prepunching. The process requires 10 passes before the welding station, because a typical roll former doesn''t have idler stands. Tube and pipe mills use idlers between almost every pass to assist in forming the round.
Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of 3000 to 270 mm (–4 to –35 mesh). Grinding action is by line contact between the rods extending the length of the mill. Rods tumble and spin in roughly parallel alignment simulating a series of roll crushers. This results in preferential grinding of ...
