Baowu entrusts Fives with the design and supply of two cold rolling mills

China's Baowu Group, the world's largest steel producer, entrusted Fives, a global industrial engineering group, with the design and supply of two reversible cold rolling mills with automatic roll change for production of electric steel at Baoshan and Wuhan production sites.

Baowu has a diversified product portfolio, dominating China’s steel market, especially in auto sheet and electrical steel. The production of electrical steel is a top priority for the domestic market for hybrid electric vehicles and ultra-high voltage power transmission.

The cold rolling mill is key to achieve the demanded electric steel properties. Fives will supply two DMS 20Hi EcoMill - a split housing mill for the Baoshan site and a monobloc mill for the Wuhan site - for grain-oriented (GO) with high permeability (HiB) and non-grain oriented (NGO) electric steel.

Thanks to its portfolio of different technologies, Fives is able to offer tailored cold rolling mill solutions to both Baoshan and Wuhan production sites according to their specific operation and maintenance practices. The split housing mill allows for a larger gap between upper and lower work rolls during maintenance and changeover, while the monobloc mill provides better mechanical stability and dimensional properties.
