Baoshin invests in new combination mill

Chinese steel producer Baoshan is expanding its rolling mill capacity for large-format long products with a new rod mill outlet and a bar-in-coil line from Primetals. A new mini finishing mill technology increases efficiency through integrated single-family rolling and enables thermomechanical rolling at low temperatures.

Primetals has recently completed an installation at Baoshan Iron and Steel in Shanghai, China, for a new combination mill featuring both a wire rod mill outlet and bar-in-coil line to produce 600,000 tons per year of wire rod and bar products. This installation is Baoshan’s first greenfield long rolling investment since the original mill installation in 1998. The new mill is specifically designed to increase rolling mill capacity and expand size range with the wire rod mill outlet handling 7.5-to-29-millimeter rod and the bar-in-coil line handling 8-to-50-millimeter bar.

A new technology for increased rolling capacity

To reduce downtime, Primetals utilized four eDrive mini-finishing mills with 250 millimeter ultra heavy-duty roll housings for integrated single-family rolling from a standardized mill train. eDrive is one of Primetals’ newest long rolling solutions. Its purpose is to expand the already extensive capabilities of the company’s line of long rolling mill products by increasing load-carrying capacity, reducing long-term costs, enabling low temperature thermomechanical rolling, using quick-change roll units, and more.
