Process for the lubrication and cooling of the rolls and the metal strip during rolling, particularly during cold rolling of metal strips.

摘要

Method for lubricating and cooling cylinders (3, 4, 5, 6) and the metal strip (2) rolling on a roll stand (1), applied by spraying, at least on the inlet side (7a) of the roll (1), a lubricant (9) and applied by spraying on the output side (8a) of the roll (1) a cooling agent (10) and being constituted the lubricant (9) and the cooling agent (10) for liquid products with lubricating activity, cleaning and inerting or a combination thereof and are provided on the underside of the metal strip (2a) and / or on the top side of the metal strip (2b) and / or on the cylinders lower work (4) of the roll (1) and respectively on the cylinder upper work (3), characterized in that is calculated and dosed continuously quantity agent pure lubricant applied on the side surface d and inlet (7a), without a high proportion of water, with a controlled viscosity and using a physical computer model (22) such that this amount corresponds to the minimum amount of lubricant that is actually required for lamination; and wherein the physical computer model for the continuous computation of the minimal amount of agent lubricant takes into consideration continuous process data (23) - the speed of the metal strip (13), - the quality of the metal strip (14 ), - the flatness of the metal strip (11a, 11b), - the surface of the metal strip (26), - the tension of the metal strip (28), on the input side (7a) and on the side of output (8a) of the roll (1) and process data - the rolling force (29), - the diameter of the work rolls (30), - the roughness of the work rolls (31) and - the material of the cylinders (32).
