Rolling Mill Roll Pass Design

Reduction Reduction is the reduce in area from stand pass to stand pass and it manifested as a percentage of the entry stock area  [( A in - Aout) / A in ] × 100 Average reduction of whole mill calculate by it formula [1- 1/ (√n( A in / A out ) ] × 100 = R ave  Reduction and elongation  calculated by following Formula [1- ( 1 / E )] ×100 = R  General reduction and elongation [1- ( 1 / E ave)] × 100 = R ave
