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].
