Siemens crea un nuevo sistema para la desulfurización de metales que ahorra costes y aumenta la #eficiencia #innovación

A new plant for desulfurizing pig iron is reducing the costs of steel production. Developed by Siemens, this innovative process makes it possible to more precisely dose the various desulfurizing agents that are injected into the molten metal and do so more economically. The technology is based on the patented Simetal Feldhaus process, which has been adopted and further developed by Siemens. A plant of this type is currently under construction in Brazil at steel producer ArcelorMittal Monlevade S.A. Pig iron is produced by heating iron ore together with coke and various additives in a blast furnace. Sulfur present in these materials typically results in a sulfur content in the pig iron of between 200 and 600 parts per million (ppm). Depending on the grade of steel required, this sulfur content must be reduced - to as little as 10 ppm for modern high-performance steels. For ...
