2 Newsletter 1/2011 Long-product Mills New order from ArcelorMittal MEERdrive®– more flexi bility and less costs New order Loup Cooling Conveyor (LCC®). The layout, in accordance with local requirements. In spring 2012, ArcelorMittal Hochfeld GmbH with headquarters in Duisburg, Germany, will commence production of a complete new wire rod mill in Duisburg-Ruhrort enabling a wire rod production of 690,000 tpy with only one rolling strand. Tailored accordingly, the wire rod blocks in this highperformance production line are equipped with the individual drive technology (MEERdrive®) developed by SMS Meer.
The new wire rod mill has been designed to roll technically demanding grades, which are therefore of extremely high quality, to the closest tolerances. This line is characterized by compactness and efficiency and achieves an annual capacity of 690,000 t. Furnace, roughing and intermediate train The walking-beam furnace for the heating of billets measuring 155 mm square will have an output rate of 120 t/h. This is followed by a four-stand roughing train comprising HL (HousingLess) stands with downstream free runout and an intermediate train consisting of 14 CL (CantiLever) stands, each in horizontal and vertical arrangement. Equalizing section in loop arrangement The core element of the mill begins with the cooling and equalizing section in loop arrangement. Owing to this arrangement, an optimal run-in temperature for each steel grade can be preset in front of the wire rod blocks. Wire rod blocks with innovative MEERdrive® technology The wire rod finishing block with six rolling units and the FRS® block with four units (Flexible Reduction and Sizing) – both in UHD (Ultra-Heavy Duty) arrangement – are provided with our innovative individual MEERdrive® technology offering numerous benefits. The most important ones are: n total flexibility in roll pass designing n essentially simplified rolling ring management n reduced operational costs High-speed loop laying head. MEERdrive® technology in the wire rod finishing block with six rolling units. Cooling lines for high-quality finished products With the water cooling lines downstream of the wire rod block and the FRS® block as well as the 104-m-long LCC® (Loop Cooling Conveyor) for intensive and retarded cooling, all the requirements for the production of high-quality finished products are fulfilled. Furthermore, the required cooling strategies based on the CCT® model (Controlled Cooling Technology) developed by SMS Meer can be simulated, and then adjusted and controlled online during operation. The entire coil handling equipment designed to be particularly protective to the finished material is also adapted to the high-quality finished products. » Newsletter 1/2011 3
