Siroll PM Concept Continues to be Successful in China: Siemens Supplies Drives and Automation for New Plate Mill at Ningbo Iron and Steel

(PresseBox) ( München, )
Chinese steel producer Ningbo Iron and Steel Co. has awarded Siemens a contract to engineer and supply the drive and automation systems for a new 4.3-meter plate mill. All the systems and components used are part of the Siroll PM solution which was specially developed for plate mills. Commissioning of the rolling mill is scheduled for completion by the end of 2009.

Ningbo Iron and Steel Co., Ningbo, located in Zhejiang province, is currently building a new plate mill for manufacturing metal plates with widths of up to 4.3 meters. The products are mainly intended for use in ship-building. With an annual capacity of 1.6 million metric tons of plate metal, the new plant will incorporate two walking-beam furnaces, a two-stand rolling mill, a hot plate leveler, cooling beds, a shearing section and a finishing shop.

Siemens is responsible for engineering and supplying drives and automation for the rolling mill. The scope of supply also includes all the process models of the rolling mill and the hot leveler, the entire automation and instrumentation as well as a material tracking system from the furnace discharge down to the shearing section. The main motors of the mill will be powered by Sinamics SM 150 DC link converters.

The main reasons why the contract was awarded to Siemens were the company's many references in the heavy-plate sector and the fact that the local presence of Siemens Ltd. China will ensure efficient after-sales services for the plant. The project will help Siemens to further expand its market position as a supplier of electrical and automation solutions for plate mills.
