Unique new cold rolling mill for Shanghai STAL

Fives and Shanghai STAL Precision Stainless Steel Co., Ltd. have recently signed a contract for design, manufacturing and supply of a unique new 20Hi cold rolling mill. The new mill is designated for STAL’s new stainless steel plant in Shanghai’s Xin-Zhuang industrial zone in China.

STAL, a joint venture between USA’s Allegheny Ludlum and China’s Baosteel Group Corporation, specializes in manufacturing and marketing precision-rolled stainless strips. Aiming for increasing its current capacity of precision stainless steel strips, STAL has decided to extend its cold rolling workshop with a new bright annealing line and a new 20Hi cold rolling mill, to be commissioned in 2017.

Fives will design and deliver to STAL a new 20Hi cold rolling mill with the production capacity of just over 80,000 metric tons per year. From input strip 1.5mm thick it will be able to roll strip down to 0.040mm and up to 1.2mm thick. Maximum strip width is 1,250mm, and the mill will be able to produce at the minimum thickness on the full width. The new line and mill will produce ultra-thin stainless steels for high-end applications, such as smartphones and tablet computers.
