The HZ-Mill, an advanced split-housing 20-high mill from Primetals Technologies, offers several advantages over conventional 20-high mills. Designed with a large gap opening, it allows for easy strip threading and a smooth recovery after strip breakages. Additionally, the mill features a Double AS-U shape control system, ensuring a stable rolling process and improved productivity. At the Kawasaki plant, the new HZ-Mill has replaced two monoblock cold rolling mills.
Primetals Technologies has also installed a larger fume-exhaust system, contributing to a cleaner and safer working environment. Thanks to the HZ-Mill, Nippon Yakin Kogyo is able to increase production while reducing the thickness of highly functional stainless steel grades used in various demanding applications. The mill produces coils with thicknesses down to 0.2 millimeters and widths up to 1,350 millimeters, at a maximum rolling speed of 1,000 meters per minute.
