Evaluation of a new process for ironmaking: A productivity

In order to address the key issues of capital costs and CO 2 emissions in ironmaking operations, a new process was proposed combining a Rotary Hearth Furnace (RHF) and a Bath Smelter. This paper describes the construction of a productivity model for the RHF based on previous studies concerning the reduction behavior of pellets of carbon and iron iron oxides.
