Siemens VAI Slab Continuous Casting Technology-Operational results of the world's most modern bow type caster with vertical mold for the production of 355 mm thick slabs

摘要

In September 2011,the world's most modern bow type caster with vertical mold was commissioned at the steel plant No.3 at voestalpine in Linz,Austria.The caster has a basic radius of 10m and is designed for maximum slab thickness of 355 mm with a maximum width of 2200 mm and straightening is carried out with a liquid core.The latest state-of-the-art technology,with adjustable spray nozzles (3D Sprays),EcoStar rollers and the latest generation of process automation models,such as Dynacs 3D,DynaPhase and DynaGap Soft Reduction?,have been implemented to achieve the highest quality of the produced slabs.Another highlight of this project is the installation of two LiquiRob industrial robot systems on the casting platform which increase the safety of the operating personnel dramatically.This paper gives an overview about the start up and highlights of this favourable caster concept with selected operational results.
