The Siemens Industrial Solutions and Services Group (I&S) has been awarded a contract to modernize the continuous casting plant 1 of H.E.S. Hennigsdorfer Elektrostahlwerke GmbH in the German Federal State of Brandenburg. The project covers the installation of new electric power and automation technology as well as a new control and visualization system. The contract volume is EUR 1.2 million. The modernized continuous casting plant is scheduled to go on stream in August 2005.
The H.E.S. GmbH is a member of the Italian Milan-based Riva Group. The Hennigsdorf Electric Steelworks located North West of Berlin in the German Federal State of Brandenburg is equipped with two electric arc furnaces each rated at 72 MVA for melting scrap and two ladle furnaces for the after-treatment of the steel. The output of the steelworks is some 900,000 tonnes steel a year which is cast in two continuous casters using the curved-mold process to produce structural and quality steel which is further processed in the downstream rolling mill. Of the four-strand type, the curved mold continuous casting plant 1 produces quality steels as billets with cross-sections of 125 millimetres by 125 millimetres and 140 millimetres by 140 millimetres. Modernization of the continuous casting plant became necessary because spare parts supply for the existing obsolescent systems was no longer ensured.
The new project provides for the continuous casting plant to be equipped with a new power supply and distribution system as well as new basic and process automation. The automation system will be equipped throughout with programmable logical controllers Simatic S7. Operation of the plant will be from a central control room where all measured values and video images generated by cameras installed along the plant will be brought together. The control and visualization system will be of the WinCC type.
Siemens is also responsible under the contract for the installation and commissioning of all new components and systems.
