Factor H used in Rolling Calculations Solution

STEP 0: Pre-Calculation Summary

Formula Used

Factor H in Rolling Calculation = 2*sqrt(Roller Radius/Thickness after Rolling)*atan(sqrt(Roller Radius/Thickness after Rolling))*Angle made by Point Roll Center and Normal
H_r = 2*sqrt(R/h_fi)*atan(sqrt(R/h_fi))*Θ_r
This formula uses 3 Functions, 4 Variables

Functions Used

tan - The tangent of an angle is a trigonometric ratio of the length of the side opposite an angle to the length of the side adjacent to an angle in a right triangle., tan(Angle)
atan - Inverse tan is used to calculate the angle by applying the tangent ratio of the angle, which is the opposite side divided by the adjacent side of the right triangle., atan(Number)
sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

Factor H in Rolling Calculation - Factor H in Rolling Calculation is used in rolling calculations to account for the interaction between the material, the rollers, and the deformation process.
Roller Radius - (Measured in Meter) - The Roller Radius is the distance between the center and the point on the circumference of the roller.
Thickness after Rolling - (Measured in Meter) - Thickness after Rolling is the final thickness of the workpiece after the rolling process.
Angle made by Point Roll Center and Normal - (Measured in Radian) - Angle made by Point Roll Center and Normal refers to the angle between the roller centerline and the normal (vertical) to the surface of the material being rolled.

STEP 1: Convert Input(s) to Base Unit

Roller Radius: 102 Millimeter --> 0.102 Meter (Check conversion here)
Thickness after Rolling: 7.2 Millimeter --> 0.0072 Meter (Check conversion here)
Angle made by Point Roll Center and Normal: 18.5 Degree --> 0.32288591161889 Radian (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

H_r = 2*sqrt(R/h_fi)*atan(sqrt(R/h_fi))*Θ_r --> 2*sqrt(0.102/0.0072)*atan(sqrt(0.102/0.0072))*0.32288591161889

Evaluating ... ...

H_r = 3.18678262503031

STEP 3: Convert Result to Output's Unit

3.18678262503031 --> No Conversion Required

FINAL ANSWER

3.18678262503031 ≈ 3.186783 <-- Factor H in Rolling Calculation

How does pressure on rolls vary?

The pressure on rolls starts from the entry point and continues to build up till the neutral point. Similarly the exit pressure is zero at the exit point and increases towards the neutral point. At any section i, between the entry point and exit point in the rolls.
