Direct Reduction Process an overview | ScienceDirect Topics
Any coal with an ash melting temperature above 1050°C and a 10%40% VM content can be used in the Circofer. Coal with ash content <15% is preferable to keep the circulating load in the reactor, and in the case of direct charging into a smelter, the slag volume to a minimum (von Bitter et al., 1999). DRI produced by the Circofer process (>93% ...
