Out of all the variables associated with rolling, none is more important than friction in the roll bite. Friction in rolling, as in many other mechanical processes can be a best friend or a fatal enemy, and its control within an optimum range for each process is essential. The friction is the interconnected phenomena; material, lubrication and heat transfer at the contact surface in cold rolling. Moreover, the friction behavior in industrial environment is highly unclear. It is important to break down many tribological attributes in actual cold rolling into simple laboratory tests. The proposed hybrid lubrication system is helpful to achieve higher rolling speed and more stable rolling for improving the productivity of tandem cold rolling mills. In this paper, an estimation model of the oil film on the strip by the proposed system at the exit section of tandem cold rolling was proposed based on a combination of laboratory tests and a starvation model. The results of this research suggest that it is possible to clarify the lubrication characteristics in tandem cold rolling by using the proposed model. (C) 2015 Elsevier B.V. All rights reserved.
