Abstract

En magnetisk valsekalander som omfatter et par roterbare, parallelle valser (l, 2) og en elektromagnet forsynt med to polstykker (6, 7) som strekker seg parallelt med valsene (l, 2) og er forbundet med et felles underlag (5) gjennom et antall magnetkjerner (8) med et arrangement som er speilsymmetrisk i forhold til både. det transversale midtplan og det langsgående midtplan for kalanderen. En spole (9) og en styresolenoid (10) anbrakt i nærheten av det relevante polstykke (6, 7), er viklet omkring hver av kjernene (8), og intensiteten av den strøm som sirkulerer i spolen (9) blir regulert ved hjelp av en justeringsenhet (11) som igjen blir styrt av en reguleringsenhet (12) som mottar og behandler magnetfluksavlesningen utført av styresolenoiden (10).
