Construction case of light steel machine

Support customization of various specifications for light steel machines

In October 1972, Nippon Steel completed its No. 1 continuous annealing line at the Kimitsu plant, which initially developed the technology for continuous annealing production of cold-rolled deep-drawing carbon steel sheets, referred to as NSC-CAPL.

In July 1976, Nippon Kokan completed its No. 2 continuous annealing line at the Fukuyama plant, another technology for continuous annealing production of cold-rolled deep-drawing carbon steel sheets developed after Nippon Steel, referred to as NKK-CAL.

In July 1980, Kawasaki Steel also developed and completed its No. 2 continuous annealing line at the Chiba plant, referred to as KM-CAL.Entering the 1980s, major steel mills around the world successively built continuous annealing lines, and by the end of the 1980s, a total of 34 lines had been established.

The development continued into the 1990s, and by the end of 1996, approximately 54 continuous annealing lines had been built worldwide, with a total processing capacity exceeding 33 million tons per year. Among them, there were 26 NSC-CAPL lines, 15 NKK-CAL lines, and 13 KM-CAL lines.
