Producing steel strips in an endless process

An especially energy-efficient production process for sheet steel is now being used in China. Siemens is providing a Chinese steel manufacturer with two plants that work according to the Arvedi-ESP (Endless Strip Production) process. They produce high-quality ultrathin hot-rolled strips with widths of up to 1.6 meters and minimal thicknesses as small as 0.8 millimeters. The Arvedi-ESP process requires up to 45 percent less energy than the conventional process, which consists of separate casting and rolling steps. It therefore generates significantly smaller amounts of CO2.
