•Roll-strip contact length L •Average strip width w –despite the fact that spreading, or an increase in width, may actually occur if edger mills are not used •Average true stress of the strip in the roll gap Y avg •Assumes no friction and thus predicts lower roll force than the actual value •Power per roll (SI units)= pFLN / 60,000 kW

Cold rolling is a work hardening process used to change the structure of metals and is often used to process stainless steel. Cold rolled stainless steel as a raw material has a wide variety of applications in medical, aerospace and automotive engineering.

What Is A Rolling Mill? In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform. The concept is similar to the rolling of dough. …

A two-stand reversing cold mill can deliver capacities between 300,000 t/a of thin-gauge products or 1,000,000 t/a and more of thicker-gauge products. Main benefits of Primetals Technologies' reversing cold mills. High production capacity and yield; Flexible, low …

Cold rolling can be used to change the gauge of steel sheet metal. Cold rolling is a process used in manufacturing and finishing environments to change the thickness, or gauge, of metals or glass. Used mostly in steel mills, cold rolling involves threading flattened steel into a machine that advances the material through a set of rolls.

common process of cold rolling operation known as chatter. This happened due to numerous discrepancies occurring during manufacturing process, such as roll vibration, variation in strip tension and negative damping [1]. Chatters lead to thickness variation (across the width), surface damage and undesirable noise at work place.

Mechanics of Cold Rolling of Thin Strip 443 where yiw is the vertical deflection of the work roll at element i, gijw (, ) is the influence function for the work roll deflection due to the combined bending and shear forces generated by rolling load, giwf is the influence function for the work roll deflection due to the force generated by the roll bending mechanism, k represents the minimum element

Abstract: A deformation model of roll system in aluminum cold rolling mill applied to online control in the actual production, was established by elastic cantilever beam method and the influence function method processing ideas. The influences of working roll edge contact on the forces acting on the roll system and the cross-sectional shape of aluminum strip in the process of thin aluminum ...

Cold roll forming technology. Introduced in France in 1930 by Mr. Paul BAP, founder of Profilafroid, the steel profiles made from steel coils, also called strips in rolls, were already developed in other countries. Especially in the United States, England and Germany. …
