Cold/Hot Rolling Mill

cold/hot rolling mill is a plant which is used to shape and process metal by passing it between a pair of working rolls Components of rolling mills:The work rolls and their bearings - made of material harder than it is intended to roll The backup rolls and its bearings -are intended to provide rigid support required by the working rolls to prevent their flexure or bending under the rolling load The Mill Foundation - reinforced concrete for every ton of mill weight Rolling balance system - to ensure that the upper work and back up rolls are maintain in proper position relative to lower rolls Work 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 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 Motor Couplings - used to connect the shafts of motors to reduction gears in pinion stands Drive motors - rolling narrow foil product to thousands of horsepower Motor Generator Sets - constant and variable voltages applied to the motors Coilers - provides high forward tensions Mill Instrumentations - sensors to monitor all important parameter processes Operating Controls - enable the mill operator to handle rolling process
