The hot rolling of steel sheets is a highly energyintensive process. There are technical and operational issues associated with this process, and the causes of these issues can be various. This study involved analysis of one issue that has a great influence on the resulting surface quality of rolled sheet metal: rolled foreign material. After the sheet cools, rolled foreign material tends to ...

In this work, a rolling simulation system for the hot rolling of steel is elaborated. The system is capable of simulating rolling of slabs and blooms, as well as round or square billets, in different symmetric or asymmetric forms in continuous, reversing, or combined rolling. Groove geometries are userdefined and an arbitrary number of rolling stands and distances between them may be used.

When hot rolling steel in the laboratory, using relatively small rolling mills, values of 420 kW/m 2 K appear to be the correct magnitudes. If modelling hot rolling of steel under industrial conditions, values of 50120 kW/m 2 K are more useful. In both cases, the layer of scale is an important parameter.

Roll Design1. John G. Lenard, in Primer on Flat Rolling (Second Edition), 2014 Friction and Wear. Work rolls in hot strip mills wear due to friction between the roll surface and hot strip. (Backup rolls wear as well, but under pressure with elastic deformation, the friction is much less, except for the high work roll roughness in the last stand of a sheet rolling tandem cold mill).

Abstract: Technological advantages and decreasing costs are the reasons for the success of radar measurement systems for hot rolling mills. Contrary to light waves, radar radiation at the selected frequency range is insensitive to steam and dust. With high accuracies and robustness, the radar system works under harsh environmental conditions.

Roll wear is more severe with this type of hotstrip mill than with semicontinuous and continuous hotstrip mills. However, this disadvantage can be alleviated considerably by the use of hotrolling lubricants. Steckel hot mills are capable of productivities ranging from 250,000 to over 1,000,000 tons per year.

The looper control of hot strip finishing mill is one of the most critical control items in hot strip rolling mill process. It is a highly complex nonlinear system, with strong states coupling and uncertainty that present a difficult control challenge. Loopers are placed between finishing mill stands not only to control the mass flow of the two stands but also to generate a constant specific ...

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 function, rolling mills do not generate scrap. The process of rolling affects the materials at a metallurgical level and the desired ...

Profile and shape control is utilized to maintain the dimensional quality of a rolled strip. Prediction of work roll thermal expansion is an important element in controlling the strip profile and flatness in a modern, highspeed rolling mill. In this study, a full threedimensional analytical model "based on the finite difference method under transient condition" that already was developed ...

Asymmetric hot rolling has been found to decrease the rolling loads, to increase recrystallisation kinetics and to refine the grain size. Thereby this rolling practice opens the way to save energy, to decrease hot band thickness, to enlarge formats, to increase strength, to reduce alloying additions and to improve formability.
