Abstract
A rolling mill for wire or bar steel with a continuous light section steel or wire train, comprising a single or multi-line breakdown train with pilot stands, at least one single intermediate train comprising a cooling distance with subsequent soaking distance and a group of intermediate stands located downstream of said breakdown train as well as a finishing train downstream of said intermediate train with a single line group of finishing stands is disclosed, for overcoming unequal temperature distributions across the bar length and cross-section to compensate for varying finishing velocities because of cross-sectional differences caused by unavoidable longitudinal pull between the stands of the breakdown train. Specifically, a first soaking or compensation distance 10 with 180.degree. loop of the rolled stock guided through the horizontal loop former is located between the pilot stand and the group of intermediate stands and a second compensation or soaking distance with 180.degree. loop of the rolling stock formed by a second horizontal loop former is disposed between the group of intermediate stands and the finishing stands.
