Innovation provides an edge: New S-6-high process boosts productivity at ThyssenKrupp Acciai Speciali Terni
In this way, ThyssenKrupp Acciai Speciali Terni has not only significantly consolidated the production process and boosted efficiency, it can now also market a product whose microstructure, mechanical properties and geometric tolerances are virtually the equal of a standard coldrolled strip. This new product, called 2E-Finish (cold rolled, annealed, blasted, pickled, stretch leveled) represents for some applications an attractive lowercost alternative to conventional 2D/2B (cold rolled, annealed, pickled / skin passed) finishes.
Further advantages: Hot strip can be produced in a greater range of sizes and the process chain for cold strip is shortened considerably through the combined rolling and annealing of hot strip. The reduction in hot strip thickness also gives the hot rolling mill greater flexibility, resulting in a notable increase in productivity. Moreover, the S-6high process is capable of producing also cold rolled and annealed coils in 2D finish (cold rolled, annealed, pickled) directly from the LAC10 by a double passage on the line.
"Our customers also profit directly from these technical innovations: The more compact production cycle shortens our delivery times and distinctly improves strip thickness and flatness tolerances," explains Alessandro Segala, head of the Metallurgy and Innovations department at ThyssenKrupp Acciai Speciali Terni. "This 6-Shigh process is the stateoftheart in terms of process development. It has enabled us to significantly strengthen our competitive position."
ThyssenKrupp Acciai Speciali Terni is one of the world's leading manufacturers of stainless steel flat products. As well as the service centers of Terninox, ThyssenKrupp Acciai Speciali Terni has manufacturing subsidiaries in Tubificio di Terni and Società delle Fucine. In fiscal year 2008/09 the company generated sales of around 1.7 billion euros. It employs roughly 2,800 people in Terni.
