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.

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 ...

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.

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).

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.

Abstract: It's possible for different kinds of automatic gauge control (AGC) systems working simultaneously to impact and disturb each other while adjusting their moving directions. In order to implement a decoupling control, we modified the parameters and structure of the AGC system in a hot rolling mill. As a result, it was proved that theoretically, gauge meter type AGC system and ...

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 ...
