Double-reduced cold rolled steel strip

摘要

Apparatus and method for manufacture of DR (Double Rolled) steel strip in which a continuous annealing furnace (7) is arranged for annealing of cold-reduced steel strip (1) passing continuously through said furnace, and a rolling mill (14, 15) for cold-rolling of steel strip is arranged to receive in-line the output of annealed steel strip from said furnace. The mill has at least one roll stand having a pair of work rolls (16) of which only one is driven externally. Rolling fluid, preferably free of mineral oil, is supplied to the strip being rolled in the rolling mill, and is removed from the strip prior to entry of the strip to downstream tension-applying means (10).
