Abstract

Peeling the obviated by preventing the rolls absorbing H2 from the lubricant. A fixed potential is opt applied between the rolls and the material to be rolled. This potential is opt zero, both between the rolls and between the rolls and the material to be rolled. If the lubricants have acid reaction, the cylinders are opt given a positive potential with respect to the material. The lubricant is opt such that under rolling conditions, it does not release H2; e.g. an aq. MoS2 dispersion, or an aq. synthetic material dispersion. The lubricant is opt neutral under rolling conditions; and opt resists ageing.
