HMI system for compact hot rolling mill SIEMENS VAI Metals Technologies has received an order from Baotou Steel International Economic & Trading to supply a new HMI system for the compact hot rolling mill of Baotou Iron & Steel Co Ltd. The conversion work is scheduled to be carried out in April 2010. In Inner Mongolia, Baotou Iron & Steel of China has been operating a compact hot rolling mill with an annual capacity of up to 2.8 million metric tons since 2001. The plant includes a two-strand continuous slab caster, a seven-stand finishing mill and two coilers, for which Siemens has already supplied the drive equipment and automation systems. In the context of the current project, the compact hot rolling mill is to be fitted with HMI equipment based on Simatic WinCC. All the components and systems to be used are part of the Siroll HM solution platform for hot rolling mills. This means

pipe systems and supports, valves and materials, plumbing and heating, and tools and safety equipment. The guide includes information to help customers identify the various pipe systems available for specific jobs. Among new sections are a guide to the company’s added value services, including Valvestock’s bespoke valve assembly; Plascut stainless steel plasma cutting; off- site modular pipework solutions; and tailor- made refrigeration systems. An improved chapter on sustainable technologies high- lights the work of Wolseley’s sustainable building centre. It identifies the drivers behind the move to more sustainable building products and highlights key legislation impacting those working in the industry. The guide also explains the principles behind new sustainable technologies and approaches, such as heat pumps, biomass boilers, solar thermal systems, photovoltaic cells, heat recovery and rainwater harvesting.

that the compact hot rolling mill will be the third installation at Baotou Iron & Steel to be equipped with a Siemens HMI solution after the coupled tandem pickling line and the plate mill. It was only in 2006 that Siemens expanded the six-stand finishing mill by retrofitting a seventh stand, plus a roll gap lubrication system, an automatic levelling control system (ALC) and a looper flatness control (LFC) system.
