Arcelor Mittal Group recently produced the first coil on its new hot rolling mill in Cracow, Poland.
Supplied by Siemens Metals Technologies as a turnkey installation and started up one month before the contractually agreed date, the new mill will have an annual production capacity of 2.4 million tonnes of steel. In addition to the technological parts of the facility and the complete electrical, drive, and automation systems, the project also included construction plus roll-shop and auxiliary installations, including water treatment equipment. Siemens also trained the operating and maintenance personnel and carried out commissioning.
Siemens’ technological scope of supply included a reheat furnace, reversing quarto roughing stand with hydraulic upsetting devices, an “Encopanel” insulating tunnel, and a crop shear. The six-stand finishing train is equipped with “SmartCrown” work rolls, which enable a larger adjusting range for profile and flatness control. A laminar cooling section with easily switchable “SmartCoolers” in the fine tuning zone enables precise control of the cooling process, an essential prerequisite for manufacturing special grades of steel. Two “PowerCoilers”, each with four wrapper rolls, ensure reliable winding of high-strength steel grades.
The plant produces steel strip in thicknesses from 25.4 millimeters down to 1.2 millimeters, with a maximum coil weight of 35 tonnes. With a maximum strip width of 2100 millimeters, the hot-rolling mill is one of the widest plants in Europe.
