Fives has been a major partner in designing cold rolling workshops over the last 50 years, and has been supplying more than 100 cold rolling mills and processing lines worldwide. In the flat stainless steel process, a clear distinction is made between a hot rolling section (the upstream process up to the first strip coil) and a cold rolling workshop. The cold rolling workshop covers thickness reduction, and annealing and pickling in order to achieve proper mechanical properties and the required surface quality. The final targeted surface quality covers 2D, 2B and BA (bright annealed mirror-like surface).
Fives’ scope of design and supply covers annealing and pickling lines (hot and/or cold type – HAPL / CAPL), cold rolling mills (DMS 20Hi), bright annealing lines for specific BA quality products and In-line/off-line skin-pass mills (DMS SkinPass). Fives has partnered with many clients in the past years including, POSCO-Thainox, for which it has commissioned 5 annealing and pickling lines and 3 cold rolling mills over the last 20 years. For Outokumpu, it had the contract for equipment supply for 2 CAPLs and revamping of all of the monobloc 20Hi mills in the Tornio plant (Finland). And for TISCO, Fives was the first to design and supply a hot annealing and pickling line with 14mm thickness and 2100mm width. Fives has also developed a new technology, DMS 20Hi EcoMill which allows for enhancement of strip flatness, and reduction of capital and operational expenses.
