摘要

Pure Fonte Ltee. (PFL) is developing North America's first dedicated high-purity pig iron (HPPI) facility. This paper outlines the Tenova innovative HPPI production process adopted by PFL that starts with the reduction of iron-oxide pellets - either DR grade or BF grade - in a gas-based DR module and follows with high-carbon-DRI melting in an EAF, specifically sized and designed to produce pig iron. This process route is characterized by an extremely competitive operating cost and an unparalleled environmental performance, reducing in less than half the CO_2 emissions compared to the conventional pig iron production route.
