Abstract

PURPOSE: To maintain the purity of a rolling fluid and thus ensure the quality of a product and the stability of continuous rolling operation, by backwashing the filter, followed by ultrafiltration treatment in the reuse of a rolling fluid contg. impurities while filtering.
CONSTITUTION: A rolling fluid (a) contg. impurities used to clean rolling rolls in a rolling mill 3 is fed, after removing of the impurities coming up to the surface in a tank 4, to a filter apparatus 1. In the filter apparatus 1, the rolling fluid is filtered by means of a filter cloth. The filtrate thus obtd. is transferred to a tank 5 for reuse. On the other hand, the impurities, such as machine oil and iron dust separated and collected on the filter cloth, is backwashed with compressed air (c) at a predetermined time internal, and the backwash drain (d) is continuously fed, after being temporarily held in a tank 6, into an ultrafiltration membrane apparatus 2 by means of a pump 8. In the apparatus 2, the backwash drain is filtered while circulating by making use of an ultrafiltration membrane module, thereby enabling the impurities to be concentrated. The fluid (e) which has passed the apparatus 2 is circulated for reuse.
