Cold rolling is a more complex process where the metals yield strength and hardness increase compared to the hot rolling process. Cold rolling is normally used to decrease the thickness of steel. Cold rolling is more precise than a hot rolled product. However, cold rolled steel is limited to round, square, flat and other such variations due ...

The reversing cold rolling mill is the all-rounder among the cold rolling mills Here, thin strips, thick strips, soft grades, high-strength and ultra-high-strength strips can be rolled in succession on one and the same plant. The RCM is mainly used for low carbon steels, but is also a good solution for modern grades such as silicon steels.
The so-called selective roll cooling is applied mainly for cold rolling mills to control the asymmetrical flatness deviations the strip width. There are furthermore across applications for special cast-rolling mills for narrow-gauge hot strip production. Normally, two rows of nozzles are used in one header. The row of nozzles directed to
Cold rolling reduction is an important factor that affects drawability of IF steel. It has been observed that increasing cold rolling reduction increases the r m value, at least up to 90 34.This effect has been shown in Fig. 5.14.Perhaps the most important parameters in the production of a strong 111 recrystallization texture are the annealing temperature and the time of holding 35.

Oct 08, 2014 Mill stands can be 2- high, 4-high or six-high. 4-high stands are more widely used since they give maximum advantage over other two types. Single or two stands cold rolling mills are normally reversing mills. A reversing mill is where the steel enters the rolling mill from one side, passes through to the other side and then comes back through ...
Rolls are tools used in rolling mills to reduce the cross section of metal stock. The weight of rolls may vary from a few kilograms up to 250 tonnes. Under rolling conditions the contact area between roll and stock suffers wear, the other parts of a roll - body and necks - have to be considered as normal parts of designed components under high ...
Rolling mill consisting of three rolls or known as 3 High rolling mill is typically used for performing multiple reduction passes by wrapping material around the center mill roll and performing another reduction on the opposite mill roll pair. 3 High mill can also be used with varying mill roll sizes to induce a specific percentage of reduction of material on a single side of the work piece.
