The calculation of rolling force. When manufacturing sheet products it's important to understand the rolling force. This is because you need it to set the appropriate roll gap on the mill, accounting for the stretch of the stand. The prediction of rolling force can be challenging due to the large number of interconnected process variables ...

The Sheet Metal Rolling Machine works according to the principle of three point bending. The rotation of the driven rolls being utilized to feed the metal through the rolls by means of the frictional forces present between the surface of the rolls and sheet. No lubricant is used at its presence interference with the ability to grip.
