The First Sendzimir Tandem Mill

Nisshin Steel Co. placed the world’s first Sendzimir tandem mill into operation at its Shunan works in 1969. Located in Nanyo, Japan, the plant occupies a site of approximately one-third square mile. Occupying about 18% of the 315-ft (96 meters) total installation length are four Sendzimir stands: one ZR 22N-50 and three ZR 21B-50. Once up and running, the mill’s maximum finished monthly production capacity totaled 18,300 net tons — 35% 400 series; and 65% 300 series stainless steel.
