Rolling mill for cold rolling metal sheet like carbon steel, stainless steel, silicon steel, alloy steel, etc.

·         Work rolls

·         Backup rolls - are intended to provide rigid support required by the working rolls to prevent bending under the rolling load

·         Rolling balance system - to ensure that the upper work and back up rolls are maintained in proper position relative to lower rolls

·         Roll changing devices - use of an overhead crane and a unit designed to attach to the neck of the roll to be removed from or inserted into the mill.

·         Mill protection devices - to ensure that forces applied to the backup roll chocks are not of such a magnitude to fracture the roll necks or damage the mill housing

·         Roll cooling and lubrication systems

·         Pinions - gears to divide power between the two spindles, rotating them at the same speed but in different directions

·         Gearing - to establish desired rolling speed

·         Drive motors - rolling narrow foil product to thousands of horsepower

·         Electrical controls - constant and variable voltages applied to the motors

·         Coilers and uncoilers - to unroll and roll up coils of metal
