    04.04.2012· Here iron and slag become soft, and they separate and melt down. The slag phase contains some unreduced iron oxide FeO. The reduction of this iron by solid carbon is called direct reduction: (1.1.5) C + FeO = Fe + CO. Above the cohesive zone, the gas heats up the burden. Carbon monoxide and hydrogen reduce iron oxide indirectly as gas–solid reactions: (1.1.6) CO + FeO = Fe +
