Primetals Technologies to supply reversing cold mill

Primetals Technologies was recently selected by Chinese steel producer Anshan Iron and Steel Group to supply a reversing cold mill for its steel plant in Anshan City, Liaoning province. The new 20-high HZ-mill will produce high-strength silicon steel for the fast-growing electrical steel market.

The HZ-mill, an advanced split-housing ZR-mill from Primetals Technologies, has several benefits over a conventional ZR mill. For example, the HZ-mill is designed with a large gap opening, which results in easy strip threading and a smooth recovery after strip breakages. Moreover, the roll-diameter configuration is tailored to individual needs, and the HZ-mill features a Double AS-U shape control system for a stabilized rolling process and an increase in productivity.

The HZ-mill lets operators utilize almost the entire range of the work rolls, regardless of the diameter of the intermediate rolls. This results in more options – another advantage over the monoblock ZR-mill.

A regional subsidiary of parent company Ansteel, Anshan Iron and Steel Group has a comprehensive product portfolio that includes hot-rolled sheets, cold-rolled sheets, galvanizing sheets, color-coating sheets, cold-rolled silicon steel, heavy rail, seamless pipe, section, and construction steel. Anshan is the leading supplier of steel to the automotive, bridge, and nuclear power industries in China.
