How to Calculate Pressure Acting on Rolls from Entry Side?
Pressure Acting on Rolls from Entry Side calculator uses Pressure Acting at Entry = Mean Yield Shear Stress*Thickness at Entry/Initial Thickness*exp(Coefficient of Friction*(2*sqrt(Radius of Roller/Final Thickness after Rolling)*atan(Angle made by Point Roll Center and Normal*sqrt(Radius of Roller/Final Thickness after Rolling))-2*sqrt(Radius of Roller/Final Thickness after Rolling)*atan(Angle of Bite*sqrt(Radius of Roller/Final Thickness after Rolling)))) to calculate the Pressure Acting at Entry, The Pressure acting on rolls from entry side is the pressure exerted on the sheet by the roll, it is essential for reducing material thickness, controlling shape, improving surface finish, and minimizing defects. Pressure Acting at Entry is denoted by Pen symbol.
How to calculate Pressure Acting on Rolls from Entry Side using this online calculator? To use this online calculator for Pressure Acting on Rolls from Entry Side, enter Mean Yield Shear Stress (Se), Thickness at Entry (he), Initial Thickness (hin), Coefficient of Friction (μrp), Radius of Roller (Rroller), Final Thickness after Rolling (hf), Angle made by Point Roll Center and Normal (Θr) & Angle of Bite (αbite) and hit the calculate button. Here is how the Pressure Acting on Rolls from Entry Side calculation can be explained with given input values -> 3.5E-12 = 4359.69*1.1E-05/0.0035*exp(0.5*(2*sqrt(0.104/0.0075)*atan(0.32288591161889*sqrt(0.104/0.0075))-2*sqrt(0.104/0.0075)*atan(0.785398163397301*sqrt(0.104/0.0075)))).
