1. What is 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. It helps quantify the deformation characteristics during the rolling operation.

2. How Does the Calculator Work?

The calculator uses the Factor H formula:

\[ Hr = 2 \times \sqrt{\frac{R}{hfi}} \times \tan^{-1}\left(\sqrt{\frac{R}{hfi}}\right) \times \Theta r \]

Where:

\( Hr \) — Factor H in Rolling Calculation
\( R \) — Roller Radius (m)
\( hfi \) — Thickness after Rolling (m)
\( \Theta r \) — Angle made by Point Roll Center and Normal (rad)

Explanation: The formula calculates the deformation factor by considering the geometric relationship between roller radius, final thickness, and the angle between roller centerline and material normal.

3. Importance of Factor H Calculation

Details: Accurate calculation of Factor H is crucial for predicting material deformation, optimizing rolling parameters, and ensuring product quality in metal forming processes.

4. Using the Calculator

Tips: Enter roller radius and thickness in meters, angle in radians. All values must be positive and non-zero for accurate calculation.
