The annealing and pickling line for cold-rolled stainless steel strip supplied by Andritz to Taiyuan Iron and Steel (TISCO), China, one of the largest worldwide, was taken over by the customer in 2007. The plant processes 500,000 metric tons of stainless steel strip per year (strip width: 800-1,320 mm; strip thickness: 0.3-3.0 mm). Shown here is the pickling section.

The annealing and pickling line for cold-rolled stainless steel strip that Andritz delivered to Shanghai Krupp Stainless (SKS), China handles strip thicknesses from 0.3 to 3.0 mm and strip widths of up to 1,340 mm at speeds of up to 120 m/min. Shown here is the upcoiler group (upcoiler operating speed up to 200 m/min, with simultaneous, crease-free feed of protective paper; upcoiling with exactly placed edges).

PROFILE

The Rolling Mills and Strip Processing Lines Business Area designs and builds complete lines for the production and further processing of cold-rolled stainless steel, carbon steel, and non-ferrous metal strips. These lines consist of equipment for cold rolling, surface treatment, strip coating and finishing, stamping and deep drawing, and acid regeneration. Key equipment is developed in-house and manufactured at the Business Area’s own facilities.

The Andritz Group is one of the very few single-source suppliers worldwide capable of providing all technologies and processes involved in the manufacturing of stainless steel strip (cold-rolling, annealing, pickling, and finishing) on a comprehensive basis (mechanical, process, and electrical equipment). This ensures minimized interfaces and takes the interdependencies of the overall process into consideration.
