Recent Developments in Coiler Pinch Roll Technology
Hot Strip Mill Roll INTRODUCTION Recently, coiler pinch rolls have become more recognized as a critical component of the hot strip mill. Once considered a commodity product, pinch rolls have gained increased attention as hot strip mill productivity and the demand forA SURVEY OF THE LOOPER-TENSION CONTROL TECHNOLOGY IN HOT,abnormal rolling condition. Thus, the specifications of dimensional quality and mass flow in hot rolling mills can be satisfied by proper control of the strip tension and looper angle. Figure 1 shows the tension and looper control in a typical finishing mill. Traditionally, looper angle control has been per-Hot Strip Mill - an overview | ScienceDirect Topics,John G. Lenard, in Primer on Flat Rolling (Second Edition), 2014 3.5 Friction and Wear. Work rolls in hot strip mills wear due to friction between the roll surface and hot strip. (Back-up rolls wear as well, but under pressure with elastic deformation, the friction is much less, except for the high work roll roughness in the last stand of a sheet rolling tandem cold mill).Hot strip mills (Steel) - SMS group,You'll appreciate X-Roll ® hot strip mills from SMS group as all-round plants for high-quality hot strip.
