Anyang's continuous caster produces: The world's widest steel slabs

摘要

At up to 3 300 mm, SMS Demag's continuous caster supplied to Anyang Iron and Steel Company in the People's Republic of China now produces the world's widest steel slabs. For the production of slabs which are more than 2 500 mm wide, the design of a continuous caster must satisfy specific requirements in terms of the technological boundary conditions, This concerns the investigation of the flow characteristics within the mould and tundish, a sufficient Strand support System plus the design of the secondary cooling concept. This paper presents the design and technological features which ensure that sophisticated steel grades can be cast at high speeds to yield slabs of a constantly high quality. ong-span bridges create new connections. Heavy-jduty container ships bring goods and raw mater-ials day by day. Cranes erect gigantic skyscrapers. The rapid growth of China's metropolitan areas is driven mainly by one material: steel. In the scen-arios described above, the essential part of the struc-tures depends on large amounts of high-grade heavy steel plates.
