Rolling | SpringerLink
A 200-mm-wide strip is cold rolled by a two-high mill in thickness from 2 to 1.5 mm, without any spread. The rolls are 300 mm in diameter and operate at 100 rpm. If the rolling load is 1.1 MN, determine the mill power required for this cold reduction, assuming typical value of lever arm ratio for cold rolling.
A Review on Chatter Analysis in Cold Rolling process
corporation production mill. The computer simulation have been used to study chatters and showed the variation of natural frequency with variety of factors viz. friction, rolling speed, tension, reduction and strip width. The stability criterion for rolling mill was derived analytically using the factors causing negative and positive damping [8].
The effect of roll roughness and lubricant viscosity on the …
The tribological mechanisms of three commercially available oil-in-water emulsions were examined during cold rolling of low carbon steel strips.The independent variables in the study were the viscosity of the oil in the emulsions, the roll roughness, the roll velocity and the reduction. It was concluded that roll roughness plays an integral role …

Strip Cold Rolling | SpringerLink
Strip cold rolling is a technology for metal sheet and strip rolling below recrystallization temperature. The raw material is usually hot-rolled steel strip or plate which is rolled by a cold rolling mill at normal temperature to produce steel profiles. Cold-rolled strip steel and steel sheet have advantages, such as smooth surface, high ...
How Cold Rolling Mills Work | Cold Rolling Process
Cold-rolled steel is a type of steel that has undergone further processing after the initial hot-rolling process. Once the steel undergoes hot rolling, you need to cool it with a finishing technique that lets you compress it using rollers at a relatively low temperature. After cold rolling, the steel may be further processed through annealing ...
