Iron and steel industry is the base of the country economy. It is the important support of the social developing, and is the important basic industry of the modern economic. This paper studies the rolling mechanical model of rolling process control, fluid stress model, rolling torque model and the temperature change models. And put forward an on-line modeling method of rolling mill based Least-...

In this paper, a kinematic optimal design of a new parallel-type rolling mill based upon Stewart platform manipulator is investigated. The objective of this new parallel-type rolling mill is to permit an integrated control of the strip thickness, strip shape, pair crossing angle, uniform wear of the rolls, and tension of the strip. A manipulability measure, as the ratio of the manipulability el...

The decrease in hot strength or even rolling load as strain increases in some stands of the finishing hot strip mill with no metallurgical reasons is a relatively common event. Apparently this fact is associated with modification in the tribological conditions between rolling stock and work roll surfaces due to unexpected interactions with scale. The aim of this work was to determine the values...

The flatness target curve is important in the control theory. accuracy of an factor to determine load means and quality. Aiming at defect that crown each pass after rolling cannot be controlled quantitatively traditional formulation cold rolling, a new method considering was proposed. Specifically, can set by combining total proportional change hot field instability discrimination model field. ...

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...

In this paper, the influence of rolling parameters on generation wear particles is studied experimentally using a pilot scale mill. Further, multi-scale model proposed to predict amount generated in cold processes operating under boundary lubrication. Rolling experiments revealed that thickness reduction and roll roughness are two dominant process control processes. Analysis size distribution s...
