rolling speed, rolling time) and tribological factors (friction, wear, lubricant) [1]. In the first part of the thesis it is shown that biodegradable synthetic water-based lubricants, which are less detrimental to the environment, may substitute conventional mineral oils and oil-in-water emulsions in cold rolling. This is also clear from [2-4].

INTRODUCTION. A rolling mill is a machine or factory for shaping metal by passing it between a pair of work rolls.. Rolling mills are often incorporated into integrated steelworks, but also exist as separate plants and can be used for other metals, and other materials.. Rolling mills historically have been of several kinds: Depending on the …
