Hot rolling is an important steel production process. Rolls in a hot rolling mill cost significantly and influence quality of products. Wear is a major factor of roll fault. So, it is very important to study roll wear at high temperature, although roll wear study in a real rolling mill is very difficult, especially for a hot rolling mill. To meet the need of practical production for the ...

rolling mill, dedicated roll cooling systems are required to fulfill the required functions. Examples are suitable roll cooling and lubricationsystems to fully utilize the advantages of HSS rolls in hot strip mills, and selective roll cooling systems as a method to control the flatness of the strip in cold rolling mills.
A method and apparatus for applying hot rolling mill lubricants composed of water and difficultly dispersible oil to the rolls of rolling stands used to reduce hot steel whereby the lubricant is applied only during the period when the workpiece contacts the rolls of the rolling stands. The oil is continuously circulated in a loop system to maintain it at a desired temperature range, and …
A mathematical model has been developed to compute the changes in the austenite grain size during rolling in a hot-strip mill. The heat-transfer model described in the first of this series of papers has been employed to calculate the temperature distribution through the thickness which serves as a basis for the microstructure model. Single-and double-hit compression tests have …

Keywords: hot rolling, metallurgy 1. Introduction Hot rolling has usually been performed at as high temperatures as possible, thereby reducing the load on the work rolls and mill stands as well as contributing to increased productivity. Alloying wrth Mn, Cr, Ni. etc., was considered when increased strengths were sought.
Mill scale is one of waste materials which is produced as a result of hot rolling of steel in all steel companies. On the other hand, mill scale is considered a rich iron source with minimum impurities. This work aims at conversion of mill scale by adjusting smelting processes to produce different valuable products. The smelting processes were carried out using carbothermic …
In a plate rolling production line, thermomechanically controlled processing is critical for plate quality. In this paper, a set of intermediate cooling equipment of a two-stand plate mill with super density nozzles, medium pressure, and small flow is developed. Based on a simplified dynamic model, a cooling control scheme with combined feedforward, feedback, and adaptive …
In the design of the rolling mill plants, it is fundamental to study the behaviour of the deformation process to assess the main process variables (such as torque and rolling force) in all operating conditions.In this paper, a finite element model is developed and the numerical simulations of the plastic deformation process, in the hot rolling mill of AISI 304 stainless steel, are shown.

John G. Lenard, in Primer on Flat Rolling (Second Edition), 2014 3.5 Friction and Wear. Work rolls in hot strip mills wear due to friction between the roll surface and hot strip. (Back-up 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).
The hot rolling of steel was simulated using data from laboratory experiments and mill trials. Particular attention was paid to prediction of the temperature …
