Rolling Mills

Rolling Mills

A Rolling Mill or Reduction Mill has a common construction independent of the specific type of rolling being performed:

• 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 maintain 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
• Uncoilers and recoilers - to unroll and roll up coils of metal

Slabs are the feed material for hot strip mills or plate mills and blooms are rolled to billets in a billet mill or large sections in a structural mill. The output from a strip mill is coiled and, subsequently, used as the feed for a cold rolling mill or used directly by fabricators.
