Abstract
Method for the continuous manufacture of steel strip in which steel strip is fed into an annealing furnace at a certain feed-in rate and drawn out of the furnace at a rate higher than the feed-in rate while subjecting the steel strip to a pulling force in the annealing furnace at a temperature above the recrystallization temperature of the steel in the region of 1000.degree. to 1250.degree. C. This results in the introduction of a permanent stretch of the steel strip corresponding to the difference between the feed-out and feed-in rates as well as a reduction in the cross-section of the strip corresponding to the elongation and a reduction of the strip thickness and strip width.
