Baosteel Shanghai orders upgrade of medium gauge slitting line

At the end of December 2015, Danieli and Baoshan Iron & Steel Co. Ltd reached an agreement for the modernization of the medium gauge slitting line.

The project is part of a general upgrade program of the overall cold processing facilities located in Shanghai, which Baosteel is developing in order to face the market challenge in the next 20 years.
The original line was provided by another European manufacturing company in the middle of the 90s, and is no longer in a position to guarantee the expected product quality. A downgrade in the edge trimming quality, as well as a significant limitation in the cutting capability were the main concerns for the new HSLA products developed by Baosteel.
A new trimmer, capable of processing grades up to 1200 MPa will operate a thickness range between 1.2 to 12.7mm and up to 1900mm in width. The new heavy-duty machine will be equipped with massive discs (650mm in diameter) for the high strength products as well as a powerful scrap chopper. Automatic knives gap adjustment for the control of cutting quality is also part of the machine’s features, as well as main trimming heads auto-alignment for the line yield optimization.
The machine will be assembled in DCS, and then shipped to the job site. The slitting line upgrade will start by the end of 2016 in various steps, and the general start-up, including the new trimmer, is expected to be in spring 2017.

The order received follows the past successful cooperation had with Baosteel for the HSM1780 in Meishan for flat products, and other important projects for the bloom caster upgrade and the new slab grinder in Shanghai.
