Beschreibung
Zusammenfassung:	A cold-rolled steel strip mfg. appts. comprises continuous cold redn. equipment and continuous annealing equipment linked directly together. A tension-leveller-type scale breaker, a scale scrubbing brush unit and an immersion-type continuous pickling tank are installed upstream of the cold redn. equipment. The appts. permits direct linkage of continuous picking, cold redn. and annealing processes without employing a long looper. The tension-leveller-type scale breaker does not elongate the stock more than 7%.
