High-performance steel strip

Wälzholz relied on Danieli to expand production of high-performance steel strip.

Mill housings of the 4-high Danieli Fröhling cold rolling mill were successfully installed in Taicang, Jiangsu province, China.

The new cold reversing mill is designed to roll a wide product mix of special steel grades, from an entry thickness of more than 5 mm down to a finish thickness of below 1 mm at a maximum strip width of 670 mm. The mill can also be operated in skin-pass mode.

The mill is designed with independently driven, “twin drive” work rolls, and high-torque drive spindles.

Danieli Automation will provide electrics and automation, including HiPAC automation system which provides real-time automatic thickness and flatness control. An intelligent data analysis systems, ready for Industry 4.0, will be connected to Wälzholz proprietary process data management system.

Danieli is responsible for full equipment turn-key supply, starting from design and manufacturing, until complete erection and commissioning activity.

The cooperation will also extend beyond the final plant acceptance aiming for a long-term process enhancement support and service.

The project is lead by Danieli Fröhling, in close collaboration with the Wälzholz headquaters in Germany.
