# Yield Cost Calculation In Hot Roll Mill

Cascade control uses the reduction concept (R Factor) to calculate the mill cascade speed reference This parameter directly related to rolling fundamentals simplifies the setup and operator control During production the loop and tension control automatically adjust the R Factor ensuring minimum material stress between the stands

• ### Plate Rolling Rolls On The Fabricator

When a sheet of this material is rolled its yield strength increases proportionally to the number of bending steps until the yield strength reaches a value close to 360 MPa (50 000 PSI) This is why such work hardening (or self hardening) phenomena should be taken into account when evaluating the rolling capacity of a particular machine
