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).
Claims14
An operating method for a reversing mill for reverse milling a stock, wherein the mill comprises at least one reversing stand with rolls for rolling a metal stock, the method comprises:
- providing a lubricated stock before starting an initial pass in a sequence of passes through the reversing mill, the lubricated stock being a lubricated rolled strip;
- passing the lubricated 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 with a lubricant 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;
- and
- cooling the reversing stand with a flow of coolant completely decoupled from the supply of lubricant by directly applying coolant that is completely separate in composition, flow rate, temperature, and site of application from the lubricant to at least one of the rolls of the reversing stand.
