Hot Strip Mill Reversing Rougher Mill Study: Yer: EreliTURKEY: veren: Erdemir: Proje Tanm: Detection and correction of the causes of the movements of the rough rolling coils of the reversal by the UEC firm. In Place Machining company performed rolling survey and measurements.
Secondary scale on hot strip and the impact on wear is another issue. Stresses from Hertzian pressure in 4high cold mill back up rolls were measured years ago, the results were never published, but of high interest also, maybe later. K. H. Schr#246;der July 2003 K. H. Schr#246;der: A BASIC UNDERSTANDING OF THE MECHANICS OF ROLLING MILL ROLLS
John G. Lenard, in Primer on Flat Rolling (Second Edition), 2014. Generation III Coil Box Hot Strip Mills. In the 1970s, Stelco of Canada developed the hot coil box designed for installation in hot strip mills ead of the finish mill for coiling the transfer bar from the roughing mill and uncoiling it into the finishing mill. The coil box reduced the distance between the roughing mill
A pickled hot coil is inserted to the payoff reel, off gauge is implemented by applying tension due to friction force using a strip press in the mill. In the case when productiv ity is reverse rolling is continuously continued by ho lding the material again with the tension reel 1).
