The MIDREX process is a shafttype direct reduction process where iron ore pellets, lump iron ore or a combination are reduced in a Vertical Shaft (reduction furnace) to metallic iron by means of a reduction gas (see Figure ) [9].
The lining of a shaft performs several functions including stabilising the walls of the shaft, providing structural support to the guides for the conveyancing systems, as well as to optimising air flow for the mine ventilation design. Therefore, selection of the most appropriate type of shaft lining needs to be considered during the design phase. This document provides a highlevel .
Both process are based on shaft furnaces in which reducing gases flow in countercurrent to iron ore pellets heating them and reducing iron. The reducing gases are generated by alytic reform of methane. Reforming in Midrex happens mainly by reaction with CO2 and in Energiron with H2O. There is a process version without a reformer, the Energiron ZR. In this process natural gas is injected ...
