Rotary hearth furnaces (RHFs) are used to process solid dust; their key function is to recover iron-bearing solid wastes in the internal system [23,24]. Dust is mixed with carbonaceous material to yield an unprocessed ('green') pellet, which is then reduced in a high-temperature (> 1200 °C) atmosphere while the furnace is rotated [25].
A Review on Processing of Electric Arc Furnace Dust (EAFD
A rotary hearth furnace is a rotating torus ring furnace minimizing the layout space. Figure 2 shows the configuration of RHF process. RHF technology uses pulverized non-coking coal as reducing agent. The EAF dust is pelletized or briquetted with carbon reactant . The pellets are fed into RHF, which consists of three different zones maintained ...
