OSTI ID:577502
The new DRI melting process can effectively and economically produce high quality molten iron. This process utilizes hot charging of DRI directly from a reduction furnace into a dedicated new melting furnace. The molten iron from this DRI premelter can be charged into a steelmaking furnace, such as an electric arc furnace (EAF), where the molten iron, together with other iron sources, can be processed to produce steel. Alternatively the molten iron can be pigged or granulated for off-site merchant sales. Comprehensive research and development of the new process has been conducted including operational process simulation, melting tests using FASTMET DRI, slag technology development, and refractory corrosion testing. This paper describes the process concept, its operational characteristics and further applications of the process.
