9th ECCC European Continuous Casting Conference – ECCC 2017

Abstract China’s first twin-roll strip casting demonstration industrial plant (NBS Project) with strip width of 1340 mm was built in 2014 by Baosteel in Ningbo, China. After a year of commissioning, the demo plant was put into stable casting and rolling production in 2015. The longest continuous casting time reached 4h and a thickness of 0.9mm ultra-thin carbon steel strip was produced successfully. This paper describes development of strip casting technology by Baosteel, and technical specifications of the strip caster at the demo plant. Discussion focuses on several specific equipment, such as casting roll with long service life, and the device for rapidly changing casting roll.
