Section 3 using multi-level regression technique. Concluding remarks and future works are discussed in the last section. INTRODUCTION TO THE SENSING SYSTEM FOR HOT ROLLING PROCESSES Hot rolling process is a very complicated process. Figure 2 illustrates a layout of a sensing system of a hot rolling process. The whole process can be...The mechanical rolling conditions in hot strip mills are precisely defined by various variables, which are taken directly froth the rolling schedule (separation force, torque. speed. strip thickness) or calculated from figures of the rolling schedule and dimensions of the mill (strip reduction, roll diameter etc.). These variables allow to describe the mechanical rolling conditions of all ...

Flat Rolling •Roll Force: F= LwY avg •Roll-strip contact length L •Average strip width w –despite the fact that spreading, or an increase in width, may actually occur if edger mills are not used •Average true stress of the strip in the roll gap Y avg •Assumes no friction and thus predicts lower roll force than the actual value...Various configurations of rolling mills: (d) cluster mill Cluster Mill 22 Variousconfigurations of rolling mills: (e) tandem rolling mill. Tandem Rolling Mill Rolling mills have several stages, where the each stage successively reduces the thickness of the stock until the desired cross section is achieved.
