RFS-4 - Roll Force Measurement system

Our roll force measurement systems have a unique design that enable them either to be used to retrofit older mills or be applied directly, as original equipment, to new mills. In both cases, extensometer kits weld directly to existing posts, so no additional mill modification is required.

Rolling mill separation forces are measured accurately and conveniently with the RFS-4 system, which is the product of many years of continuous development and improvement. Extensometers on the mill posts provide an electrical signal proportional to the mill separation force. The extensometers typically are installed on both sides of both mill posts to ensure that forces on the drive and work sides of the mill are balanced. Standard configuration requires four extensometers, installed as depicted above, to eliminate bending error. However, in some cases only two mounting locations are available. Roll force can be measured with only two extensometers, provided that one unit is mounted on each post. If this configuration is used, extensometers must be mounted symmetrically, i.e., both on the inside or both on the outside of the mill posts.
