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 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 . F r = rolling resistance or rolling friction (N, lb f). c = rolling resistance coefficient - dimensionless (coefficient of rolling friction - CRF)Fundamental concept of metal rolling - mtixtl.com,•Frictional force is needed to pull the metal into the rolls and responsible for a large portion of the rolling load. •High friction results in high rolling load, a steep friction hill and great tendency for edge cracking. •The friction varies from point to point along the contact arc of the roll.
Rolling mill guide equipments play a major role in ensuring the surface quality of the rolled product. The guides are to be designed for the wide variety of stock sizes and shapes which are normally encountered in the long product rolling. In modern long product rolling mills roller guides are normally used both for entry and exit guides.A BASIC UNDERSTANDING OF THE MECHANICS OF ROLLING MILL,by design limits for maximum separation force, torque, Hertzian pressure etc, but these criteria are valid only under so called “normal rolling conditions” and even these change continuously with progressive wear in the contact zone.
