Metallurgical dusts can be recycled through direct reduction in rotary hearth furnaces (RHFs) via addition into carbon-based composite pellets. While iron in the dust is recycled, several heavy and alkali metal elements harmful for blast furnace operation, including Zn, Pb, K, and Na, can also be separated and then recycled. However, there is …

The rotary hearth furnace allows for placement of large pieces or baskets of product onto a solid refractory or alloy hearth. From the point of entry, they rotate in a horizontal circular motion similar to a lazy susan mechanism until the rotation is complete. The load may be retracted through the same entry door or through a separate exit door ...

＊2 Research & Development Department, Iron Unit Division, Natural Resources & Engineering Business Kobe Steel has developed coal-based direct reduction (DR) technologies, the FASTMET, FASTMELT and ITmk3 processes, which reduce carbon composite agglomerates (pellets or briquettes) on the hearth of a rotary hearth …
The rotary hearth furnaces of the DH product line are optimally suited for continuous processes on a small floor space. They are designed for preheating processes such as the preheating of metal parts for forging or for preheating of moulds. Charging and discharging can, be done at one position – either by a person or fully automatic. The hearth rotates …
The coal-based DR processes with rotary hearth furnace and rotary kiln can directly use coal for DRI/HBI production. If shaft furnace or fluidized bed technology is applied for the reduction stage, the coal has to be converted to reducing gas in an additional coal gasification step (Yang et al. 2019).
