Home Rolling Mills Modeling

The dynamic characteristics in a rolling process have been investigated with various methods, but a mathematical model to predict actual chatter vibration has not been established. In this paper, we propose a mathematical model of a cold rolling mill to predict chatter vibration. The mathematical model was verified by experiment and theoretical analysis. The chatter …

Rolling Mill (or roll stand or steel rolling mill) is a machine in which all the equipment for metal rolling like rolls, bearings, housing, motors, frame, power system, etc are set up to perform a metal rolling operation. In steel rolling mills, workpiece having greater thickness is fed through the rollers and the final workpiece with reduced ...

Adventures in Modeling a Rolling Mill Model Railroad . This rolling mill and the rest of your mill complex in my humble opinion truly capture heavy industry in scale The detail down to the reflection of hot steel ingots by the rollers in the rolling mill make me see this as not only a nice piece of scale railroading but a tribute to the strength of the steel industry a vital capability truly ...


The state space model formulation is used in the minimization of the strip thickness variations in a hot rolling mill to lead to a less output thickness variations with the real industrial data. In this paper, a real application of opti- mal control of a hot rolling mill is presented. It is used the state space model formulation in the minimization of the strip thickness variations.

The Coke Ovens Overall Mill Layout. The Steel Rolling Mill will have to be designed and 3D printed. I will share the designs as I complete them. In order to model this, I needed a layout of a real steel mill and I can find no better example than José Balan Filho's modeling of the Valene steel mill. His passionate development of the mill is an exceptional example of modeling.


The hot rolling mill design is prepared with a virtual work-place, which enables the users to either prepare a hot rolling mill design from the scratch or select and fine-tune an existing project of a rolling mill common scheme. Moreover, the user can upload new material or devices models and use them in the simulation process.

During the last 90 years, a lot of works have been published about rolling theories for the two-roll rolling process (2RP). In the last decades, the three-roll process (3RP) has become a significant technique in the production of wire rod and bars, as it allows to cover a wide range of finished dimensions with one pass design, or to realize very close tolerances, depending on the pass …


What Is a Rolling Mill? At its most basic principle, a rolling mill is a machine that reduces the thickness of a metal without sacing any of the material – meaning material is always displaced and never lost. By design and …


In this paper, a soft sensor is developed for the hot steel rolling mill process using least-squares support vector machines and a properly designed bias update term. It is shown that the system can handle multiple different operating conditions (different strip thickness setpoints, and input conditions).
