The purpose of this work is to evaluate the performance several wear models, either with different mathematical formulation or definition unknown coefficients, on prediction work-roll amplitude in Hot Strip Mills (HSM). To achieve goal, a classical model calibration approach based inverse optimization has been developed calibrate these models. A large industrial hot rolling database composed by...

On line quality evaluation is an important domain particularly in the complex processes where the characteristic of the product quality is difficult to measure directly. Evaluation based modelling techniques can be considered as an alternative to solve such complex problem. We consider in this work a contribution for product quality evaluation in hot rolling using fuzzy models. Residual changes...

∗ Previous address: Department of Automation, Tianjin University, P. R. China Abstract In steel rolling industry, control of hot metal rolling process plays an important role in assuring high product quality and safe process operation. Although many advanced looper control technologies for finishing rolling process have emerged, looperless interstand tension control of roughing rolling mills re...

In multi-stand cold rolling mills an accurate synchronization of the mill drives is necessary for a good product quality and for a safe process operation. During the standard commissioning procedure the control performance of each drive is optimized individually. However, in normal operation mode the performance is then not always optimal due to the coupling of the drives by the strip being rol...

Shape is an important quality index of cold rolling strip. Up to now, many problems in the shape control domain have not been solved satisfactorily, and a review on the research progress in the shape control domain can help to seek new breakthrough directions. In the past 10 years, researches and applications of shape control models, shape control means, shape detection technology, and shape co...

ISSN 2277 – 5056 | © 2012 Bonfring Abstract--A FEM simulation study was carried out to investigate the influence of the rolling parameters on the rolling process. Using commercial FEM software, ABAQUS, a number of cases were studied. In this paper, a twodimensional Elastic-plastic finite element model to simulate the cold rolling of thick strip with different roll angular velocity and roll diam...

The effect of chemical composition and the hot rolling operations on the microstructure and mechanical properties of in situ aluminum matrix composite with Mg2Si phase as the reinforcement was studied. It was revealed that the modification by phosphorous results in the rounder (more spherical) primary and secondary (eutectic) magnesium silicide intermetallics. During hot rolling, the primary pa...
