The world's most advanced continuous casting line, the CC7 line located at voestalpine Stahl in Linz, has exceeded all expectations by breaking the 1 million ton record.
Soon after the line was put into operation it was clear that it would succeed beyond all hopes. Even the quality of the first melt was good enough for the market. After four weeks, the line went into full operation on four shifts. And the 1 million ton record was reached in just 11 months of operation. To give you an idea of how much this is, consider the following: Within one year so many slabs were produced that if they were lined up one after the other, they would form a ‘slab bridge’ from Vienna to Munich.
The optimized secondary cooling ensures excellent surface properties, even on very wide slabs. This is the first time industrial robots have been used on the casting platform. The result is improved process quality and safer working conditions. Slabs can be cast in thicknesses of 355 mm and widths of up to 2,200 mm. The production portfolio now includes heavy plates weighing up to 20 tons. Such plates are mainly used in off-shore applications.
