    PROCESS FLOW CHART The basic raw material is medium carbon & high carbon hot rolled coils The coils are slitted on slitting machine for obtaining the required width of hot rolled strips After slitting these hot rolled strips are acidly pickled through the continuous pickling line for removal of scale The Pickled coils are cold rolledRoll productivity is growing for many reasons, perhaps we can talk about a 5% increase (Roll consumption today for long products is down from 10 15 kg/t to 1 4 kg/t; for flat products from 4 6 kg/t to 1 2 kg/t; with strip casting roll consumptiA BASIC UNDERSTANDING OF THE MECHANICS OF

    Roll torque can be estimated from the rolling force Torque is equal to force multiplied by the radius at which the force acts We can assume that the roll force is acting perpendicular to the strip at a radius equal to one half of the projected arc lengt h of contact For each roll, the torque is: T = FL/2 Roll power is given by:STEEL MAKING HOT WORKING COLD WORKING wwwacciaierievalbruna stainless steels production e rg o f l a i d ra r o f ms o o Bl s l l mi g n i l l ro r o f ms o o Bl Highqualityisourstandard ® STAINLESS STEEL LONG PRODUCTS Complete process flow Chart Remelted Ingot Stock Billets Stock Stock Hot rolling in coils MuffleSTAINLESS STEEL LONG PRODUCTS Complete process

    In the roll bite the strip gains heat from friction between strip and roll and by the deformation of the metal It loses heat by contact with the roll and it is this heat which must be dissipated by the roll coolant Figure 2shows model ed temperature distributions in a roll around its circumference during hot rolling of The roll steelhotstrip mills, has increased the requirements for precise massflow and thickness control As an initial step to meet these demands, Primetals Technologies has developed a new control concept for rolling ultrathin hotrolled strip in the finishing mill of an ESP line Referred to as “ultrathin rolling control,” the systemFEATURING ROLLING AND PROCESSING Primetals
