Now we know why roll hardness is important. Next let''s discuss how to achieve and measure roll hardness. As a roll of flexible packaging film material winds, tension builds inside the roll, which is known as inwound tension or residual stress. If this stress becomes greater as the roll is wound, then the inner wraps towards the core will be put
In the Mandrel Mill Process, a solid round (billet) is used. It is heated in a rotary hearth heating furnace and then pierced by a piercer. The pierced billet or hollow shell is rolled by a mandrel mill to reduce the outside diameter and wall thickness which forms a multiple length mother tube.

: Disclaimer. The above information is an estimate only and should be treated as such. The actual round tube sizes depend on several factors that include but not limited to; the amount of material used to create the final shape (better known as forming allowance), gage thickness, etc.
Tube roll design is an organized process culminating in the production of a roll formed welded metal tube. First consideration is the products'' specific characteristics of size, shape and physical properties. The next consideration is the forming and welding machinery available to the producer.
Tube roll design begins with the selection of the most appropriate breakdown roll forming type for the application. Then a sequence of shapes representing the desired amount of bending at each mill station is developed. When we stack these shapes on top of each other they look like a flower. Hence the term, "Forming Flower".
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (, via a hand crank), working animal (, horse mill), wind or water ().
A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as .
