Coiling Steel Roll

CISDI and Meishan Steel of Baosteel Group signed a contract for hot rolling skin-passing and coil dividing line in March 2010, the project started up smoothly on April 29, 2012. CISDI undertook engineering design, erection supervision, commissioning during construction and final acceptance test, test-run supervision, technical support and service after start-up.

The designed production capacity of the mill is 600,000t/a. The steel grades mainly include high-strength multiphase steel, high-strength cold forming steel, steel for cold rolling, feedstock for cold rolling & pickling, atmospheric corrosion resistance steel, general structural steel, ultra-low carbon steel and special steel. Advanced and practical technology & equipment are provided for skin passing of the hot-rolled coils to improve surface quality, shape and mechanical properties of the strip.
 
As a compact and efficiency hot rolling skin-passing and coil-dividing line, it is equipped with pay off reel, coiler, skin passing mill, 5-roll leveler, tension device, CPC and EPC to ensure finished coil quality. The skin passing mill is provided with hydraulic screwdown, work roll positive/negative bending system and quick roll changing. The mandrel is designed to allow quick change without opening the box.
 
Smooth start-up of the project is important for product mix optimization and upgrade of technical equipment of Meishan Steel. It also plays an important role for the new 1780 mm hot strip mill performance, new product development and coil conditioning. The mill can produce qualified feedstock for cold rolling & pickling line, produce quality hot rolled commercial coils, and improve added value of products and economic benefit of the hot rolled coils by 1780 mm mill.
