Lubrication systems for tandem cold rolling mills are mainly classified as either recirculation systems or direct application systems, as shown in Fig. 1.The differences were described by Semoto and Okamoto (1992) with the historical background. Recirculation systems are mainly applied to sheet gauge products, while direct application systems are mainly used …
Lubrication is necessary to guarantee the proper functioning of rolling mills. It reduces energy consumption during rolling and improves the surface quality of rolled products. Lack of lubricant or overuse of lubricant can both cause chatter in rolling, which results in poor surface quality of the products and even damage of rolling equipment.
In recent years oil/air lubrication has been studied in various steel mill applications. The roll necks of rolling mills are one application in which oil/air lubrication systems have been utilized with favorable results. Compared to conventional lubrication used in steel mill applications, oil/air lubrication reduces environmental pollution ...

Where a sump collects said rolling lubricant after use for reuse in such rolling, also using mixtures of such components to lubricate parts of the rolling mill where leakage ...
Rolling mill chatter mechanism based on the unsteady lubrication performance. Abstract. The unsteady lubrication is one of the major causes for self-excited vibration in rolling. But it is difficult to build a rolling chatter model which considers the unsteady lubrication state in roll bite. Using the regression exponential function model of ...
The rolling process is shown in Fig. 2.1: Rolling is done both hot and cold. It is accomplishes in rolling mills. A rolling mill is a complex machine having two or more working rollers, supporting rollers, roll stands, drive motor, reducing gear, flywheel, coupling gear etc. Rollers may be plain or grooved depends upon the shape of rolled product.
Both liquid and dry-film lubricants can be used for the highly essential lubrication in sheet metal-forming in the automotive industry. Liquid lubricants are commonly applied in the press shop, whereas dry-film lubricants are applied in the rolling mill.
FOR HOT & COLD ROLLING MILLS BY: HUBERTUS WENIG * ABSTRACT . The paper describes how heat is generated in the roll gap and how roll cooling should, be applied on therolls in the best manner. In many cases roll cooling goes along with lubrication. The characteristics of the various coolants used for roll cooling are
