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.

Modeling and Control of Multi Stage Rolling Mill Process. Sheet Rolling Mill processes involve progressive thickness reduction of continuous sheet metal in multiple stages. Some of the control variables of interest are exit thickness, throughput and the tension in the sheet as it passes from one stage to the other.
Simulating a Multi-Stage Rolling Mill Process, Part 2: Tension Modeling and Simulation. From the series: Simulating a Multi-Stage Rolling Mill Process. This is the second webinar of a three-part webinar series that will highlight the use of MathWorks products for modeling and control of a multi-stage rolling mill process.
There are many intermediate web guides in cold rolling mills process such as CRM (cold rolling mill), CGL (continuous galvanizing line), EGL (electrical galvanizing line) and so on. The main functions of the web guides are to adjust the center line of the web (strip) to the center line of the steel process. So they are called CPC (center position control).
The rolling stock can be made to work with tight radius turns, but motive power is usually another story. Most common n3 motive power is in the 2-8-0 or 2-8-2 category, and can be made to run down to about 18", but runs better and looks better on 20+".
In this paper, we propose an effective mechanical-electrical-hydraulic-interfacial coupling vibration model for hot rolling mills and obtain a practical measure to relieve mill vibration. First, an experiment related to mill modulus control gain in automatic gauge control (AGC) is carried out during manufacturing. Rolling mill vibration is observed to gradually be enhanced with …

This paper describes a modeling procedure for tandem cold metal rolling, including the linearization step and system identification for control. The tandem cold rolling process is described by a mathematical model based on algebraic equations developed for control purposes and empirical relations. A state-space model is derived and detailed analyses in open loop are …

Accuracy and reliability of numerical simulation of hot rolling processes are dependent on a suitable material model, which describes metal flow behavior. In the present study, Gleeble hot compression tests were carried out at high temperatures up to 1300 °C and varying strain rates for a medium carbon micro-alloyed steel. Based on experimental results, a Johnson-Cook …
