Summary

May 18, 2007 - The Siemens Industrial Solutions and Services (I&S) Group has landed orders from Baoshan Iron & Steel Group Co. Ltd. (Baosteel) in Shanghai to supply drive and automation equipment for the modernization of the Hot Strip Rolling Mill No. 1 and expansion of the plate mill. The principal focus of both projects is to equip the production facilities with powerful and reliable drives that will increase the productivity and availability of the rolling mills. Commissioning of these modernized plants is scheduled for November 2007 and December 2008 respectively. With an annual output of 23 million metric tons, Baosteel is China's largest steel producer and the sixth largest producer worldwide. For 15 years now, the Hot Rolling Mill No. 1 has formed the backbone of the production facilities in Shanghai. The plate mill, already equipped with electrical and automation equipment from Siemens, has been in operation since 2005. This facility produces high-grade steel destined for applications in the oil and gas industry and in shipbuilding.The electrical equipment of the hot-rolling mill was replaced in stages since 1998 with the aim of increasing plant availability and improving product quality. As part of the current project, Siemens is resupplying the drives for the roughing mill (rolling stands R3 and R4) and sections of the finishing mill (rolling stand F3 and crop shear). The plate mill will be equipped with an additional roughing stand which will increase the capacity of the plant to 1.8 million metric tons per year. Siemens is supplying a twin main drive with cylindrical-rotor synchronous motors, which, at 40 revolutions per minute, will produce a rated output of 8000 kilowatts and is designed for an overload of up to 275 percent. A cycloconverter will be used to regulate the electrical supply to the equipment. The new roughing mill rolling stand will be integrated into the automation environment of the heavy-plate rolling mill which has already been implemented according to the Siroll PM concept.In both projects Siemens will be responsible for overseeing installation and commissioning.Metals Technologies (MT), a Division of the Siemens Industrial Solutions and Services (I&S) Group, is one of the world's leading engineering and plant-building companies for the iron and steel industry as well as for the flat-rolling sector of the aluminum industry and for open-cast mining. MT, which was created from the integration of Voest-Alpine Industrieanlagenbau, Linz/Austria, plus the electrical engineering product business and automation solutions of Siemens, provides a comprehensive range of supplies and services for all related technological processes and integrated automation solutions for the entire lifecycle of metallurgical plants. The Siemens Industrial Solutions and Services Group (I&S) is the integrator of systems and solutions for industrial and infrastructure facilities and global service provider for the plant and projects business covering planning, installation, operation and the entire life cycle. I&S uses its own products and systems and process technologies in order to enhance productivity and improve competitiveness of companies in the sectors of metallurgy, water treatment, pulp and paper, oil and gas, marine engineering, open-cast mining, airport logistics, postal automation, intelligent traffic systems and industrial services. In fiscal 2006(to September 30) I&S employed a total of 36,200 people worldwide and achieved total sales of EUR 8.819 billion, according to U.S. GAAP. Learn More
