PRINCIPLE. This is a forming process in which material is passed between two or more rotating tools (rollers). During longitudinal rolling, the rolling stock is moved at an angle perpendicular to the rolling axes, without rotating around its own longitudinal axis, and travels down the gap between the rollers.
In fact the small rolls come in contact with the work piece and the big roll act as back up roll. Higher reduction of the order 25:1 is possible in one pass. The mill provides forging action as well as rolling action at the same time. There will be two high mill at the .
Jan 14, 2013· Rolling Process. FOUR HIGH MILL Small-diameter rolls (less strength & rigidity) are supported by larger-diameter backup rolls CLUSTER OR SENDZIMIR Each of the work rolls is supported by two backing rolls. CONTINOUSThe objective is to decrease the thickness of the metal with anincrease in length and with little increase in width.
An important chance for optimising the productivity in rolling mills consists of combining single processes in an efficient and reliable manor. Referring to that approach, the 2 photos on this page show a 15 t crane spreader beam before and after the weighing modernisation. This crane is used to
Get this from a library! Principles and Applications of Metal Rolling. [Siddhartha Ray] -- Rolling is an important metal forming process which involves the passing of metal stock through a pair of rollers. It is categorized depending on the recrystallization temperature of the metal ...
Rolling is normally a hot working process unless specifically mensions as cold working. The metal is taken into rolls by friction and subsequently compressed to obtain the final shape. The thickness of the metal that can down into rolls depends on the roughness of the roll surface.
Thanks to a new generation of precision machining, Pepetools "ULTRA" Series rolling mills are stronger than ever. Standard on each mill is a high performance 4:1 reduction gear box, turned with a high strength forged steel handle. Each roll is precision machined from select grades of high density steel.
