Fives’ cold rolling mills chosen for stainless expansion project
On 30 June 2018, Fuxin Special Steel Co. Ltd., Taiwan and Fives, international engineering group, signed a contract for coil preparation lines and cold rolling mills for stainless steel production in China.
Fuxin Special Steel is an integrated stainless steel plant including steelmaking, casting, hot rolling and hot annealing & pickling line to produce 720,000 tons per year of various stainless steel grades in the Fujian province of China. The company has decided to expand the cold rolling workshop to produce added value final products.
For the expansion project, Fives was contracted to design, manufacture, supply and commission two coil preparation lines (CPL) and three DMS 20Hi cold rolling mills (CRM), each with 110,000 tons per year capacity. The two CPL aim to make the most of the rolling mill and optimize productivity by removing hot strip tail ends, trimming crack formations and applying leader strips.
The cold rolling mills are essential to reduce strip thickness while guaranteeing strip surface quality. Fives will supply the newest generation of DMS 20Hi CRM with the latest improvements: advanced roll gap lubrication and strip cooling technology, an improved flatness control system, enhanced safety, and easier maintenance. Strip surface quality is improved thanks to the optimized lubrication of roll bite.
The coil preparation lines, as well as CRM auxiliary equipment, will be fabricated in China by Fives’ subsidiary in Shanghai, while the critical parts of the cold rolling mills will be designed and manufactured in the Fives workshop in Ronchin, France.
Fives has been specializing in cold rolling mill design and manufacturing for more than 60 years, and has supplied more than 100 cold rolling mills and processing lines worldwide.
