Question

What is the formula for roll separating force?

Answer 1

The formula for roll separating force in rolling contact can be calculated using the following equation:

$F_s=\frac{5}{7}\cdot \frac{W\cdot R}{d}$

Where:

• $F_s$ is the roll separating force (also known as the normal separating force),
• $W$ is the total weight or load on the rolls,
• $R$ is the radius of the rolls, and
• $d$ is the diameter of the rolls.

This formula applies to the case of two rolls in contact, such as in rolling mills or rolling processes. The roll separating force represents the force required to separate the rolls due to the deformation of the material being rolled. It is essential for designing and analyzing rolling processes to ensure proper roll separation and control the thickness and quality of the rolled material.

Note that this formula assumes simplified conditions and does not consider other factors that may affect the roll separating force, such as friction, material properties, or the specific configuration of the rolling process. Actual rolling processes may involve more complex equations and considerations depending on the specific application and requirements.
