The calculation of rolling force - Innoval Technology,

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 inter-connected process variables,Online calculation model of rolling force for cold rolling,,Online calculation model of rolling force for cold rolling mill based on numerical integration Abstract: Based on comprehensive consideration of elastic and plastic deformation of both strip and work roll, an online rolling force model for tandem cold rolling mill has been developed by numerical integration method in this paper.Roll force measurement | ABB,Roll Force Measurement ABB’s Millmate roll force system is the perfect choice for measuring roll force in both hot rolling and cold rolling mills, thereby achieving correct roll gap settings and force distribution. The system is proven to be exceptionally robust and resilient to high forces as well as aggressive mill agents.

1. Hot rolling and rolling defects: 1.1 Front and back,

1. Hot rolling and rolling defects: 1.1 Front and back tensions: We have seen that the rolling load is dependent on roll diameter, higher the roll dia, higher the roll force. Similarly, smaller reductions requires lower roll force. In order to reduce the roll force, we can reduce roll diameter, or reducing the friction.Rolling Resistance - Engineering ToolBox,The force that resists the motion of a body rolling on a surface is called the rolling resistance or the rolling friction.. The rolling resistance can be expressed by the generic equation . F r = c W (1). where .
