Patent

CA 2618836

The invention relates to a method for lubricating and cooling rollers (3,4,5,6) and metal strips (2) on rolling in particular, on cold rolling of metal strips (2), wherein, on the inlet side (7a) a minimal amount of pure lubricant (9) without a high water content is continuously supplied in an online controlled manner with a controlled viscosity and lubricity depending on a number of process data measurements (23) by means of a physical computer model (22) and the equivalent process data measurements (23) from the outlet side (8a) are also used online by the physical computer model (22).

L'invention concerne un procédé servant à lubrifier et à refroidir des cylindres (3, 4, 5, 6) et une bande métallique (2) lors du laminage, notamment lors du laminage à froid de bandes métalliques (2). Selon l'invention, on applique du côté entrée (7a) une quantité minimale de lubrifiant pur (9), sans teneur élevée en eau et à viscosité et pouvoir lubrifiant contrôlés, en fonction d'une multitude de données de processus (23) en continu et de manière dosée en direct par l'intermédiaire d'un modèle de calcul physique (22). Les données de processus (23) équivalentes du côté sortie (8a) sont également mises en oeuvre en direct par l'intermédiaire du modèle de calcul physique (22).
