Abstract
Operating method for a reversing rolling mill having at least one reversing rolling stand (2) for rolling a rolled metal stock (5), wherein the stock (5) passes the at least one reversing rolling stand (2) in a sequence of alternating direction passes (7) and after each pass, the stock is wound up by a reversing reel (3, 4), wherein only rolling oil, without water as a carrier medium, is applied to the stock (5) by rolling-oil applicator (6), between the at least one reversing rolling stand (2) and the winding-up reel (31, 41).

An operating method for a reversing mill, wherein the mill comprises at least one reversing stand for rolling a metal stock,
- the method comprises passing:
- the stock through the at least one reversing stand in a sequence of passes in alternating reversed directions of travel;
- winding up the stock after each pass onto a reversing reel acting as a coiler of the stock;
- lubricating the stock prior to winding the stock on the coiler by applying rolling oil as a carrier medium to the stock, and without applying water, between the at least one reversing stand and the coiler for causing a lubricating effect solely by the rolling oil applied to the stock prior to the coiling of the stock.
A reversing mill comprising at least one reversing stand, through which metal stock passes in a sequence of alternating directions of travel;
- and
- reversing reels configured and operable for coiling and uncoiling the stock dependent on the direction of travel of the reels and the stock, the reels being located at opposite sides of the stand disposed at entry and exit sides of the stand;
- and
- a rolling oil applicator configured and operable for applying rolling oil to the stock without also applying water as a carrier medium, the applicator is disposed between the at least one reversing stand and the reversing reel then acting as the coiler, so that the stock is lubricated before the stock is wound on the coiler, wherein a lubricating effect is produced solely by the rolling oil applied to the stock prior to coiling.
