Direct Reduced Iron

Direct-reduced iron (DRI) is produced by the use of a reducing gas (often a mixture of hydrogen and carbon monoxide) rather than in a blast furnace. It may have a sponge-like structure, leading to the alternative name “sponge iron”. Suitable starting materials are very high-grade iron ores or rusted scrap steel, which could not be used by induction melting.

HDRI (hot direct reduced iron): moving the still-hot iron immediately into an electric arc furnace or Induction_Furnace, to save energy.

Induction_Furnace - for HDRI !

Gasifier - producing the reducing gas: syngas, a mixture of H and CO

Is this actually feasible on the small scale ? Are we missing something ? Does the process take place at atmospheric pressure ?
