On October 25, a Z-Hi reversing cold mill supplied by Primetals Technologies was officially inaugurated
at the Pinghu, China production site of Zhejiang Nisshin Worthington Precision Specialty Steel Co., Ltd.
The mill had commenced operation in July. It is designed to produce 120,000 metric tons per year of
precision specialty steels, mainly for automotive applications. It is the first mill of this type worldwide
capable of processing wide strips at high rolling speeds of up to 800 m/min. The aim is to serve the
world´s largest automotive market, where a significant increase in demand for special steel coils and
sheets is expected. The mill can be run in two different reduction modes and features a newly designed
quick roll changing device. Automatic gauge control(AGC) and automatic shape control (ASC) optimize
shape and flatness of the strip. The order to supply the mill was awarded to Primetals Technologies in
December 2013.
