MAGNESIUM TWIN-ROLL CASTING BENEFITS FROM ALUMINIUM HERITAGE

摘要

The history of twin-roll casting for Aluminium started in the 1950's, with the first Pechiney trials in 1956, a first patent filed in 1958 and the first industrial lines installed at the beginning of the 1960's. 60 years of technology development later, Aluminium twin-roll casting accounts for 20 to 30% of the world flat rolled production and is recognized as a low-cost flexible short route to produce a wide range of alloys with cast width up to 2300 mm. In comparison, Magnesium twin-roll casting is a young process but the same promising future can be foreseen for it, as it can largely benefit from the technology developed for Aluminium. From Pechiney to Novelis in the Aditya Birla Group, Novelis PAE has been a major actor in developing twin-roll continuous strip-casting technology for more than five decades, for Aluminium (more than 110 casters installed), and also for Magnesium (3 casters installed).
