Types of Cold Rolling Mills (With Diagram) | Metals | Metallurgy
Like hot rolling, cold rolling can be done using two-and-four-high roll arrangements. Two types of cold rolling mills commonly used are: (i) Sendzimir mill. (ii) Saxl pendulum mill. Both of these mills make use of small diameter rolls. The former type makes use of elaborate system of backing rolls of increasing diameter as shown in Fig. 6.1.

Numerical Investigation of Chatter in Cold Rolling Mills
1 Introduction. Chatter in rolling mills is the undesirable mechanical vibration observed in most of the rolling mills operating at high speed and rolling thin strips. It results in unacceptable gauge variations in the rolled strip, affects the surface quality, damages mill components and produces undesirable noise.

What is Temper Rolling?
Typically, the amount of metal thickness reduction performed at temper rolling is minimal (0.5% to 2.0%). Temper rolling is done on a temper mill, which is composed of an entry end uncoiler, a cold rolling mill stand, advanced metal thickness control equipment, oiling equipment, and an exit end recoiler. The physical properties that are ...
