  • The calculation of rolling force Innoval Technology

    Yield StrengthFrictionNeutral PointTensionThe main factor influencing the rolling force required to reduce the thickness of strip in a rolling mill is the yield strength of the material being rolled. The calculation of yield strength depends upon a wide range of factors. These are: 1. composition 2. previous work done on the material 3. thermal history 4. speed of rolling 5. change in thickness We use what’s known as a constitutive equation to calculate the material’s yield point, or flow stress. There are many forms of these equations in the academic literature, and phy
