Current approaches to Laboratory Evaluation of Lubricant for hot and cold rolling

Abstract

In cold and hot rolling of steel significant energy consumption is involved. Use of lubricants for cold rolling has been. common while use of lubricants for hot rolling is more recent. ResideB energy saving lubricants can significantly improve roll life and quality of product. One of the problems involved in developing the lubricants is prediction of lubricant performance by simpler equioment ~n the laboratory. This brief discussion note focu$es attention on the major approaches available today for lahoratory evaluation. It is considered that thoug~ the information is not exhaustive it can bring the attention of the industry the methods available. Tt is hODed that this information will stimulate discussion of the methods repDrted here
