| Abstract: | Direct reduction is an iron smelting process for producing solid DRI(Direct Reduced Iron)or HBI(Hot Briquetted Iron)using natural gas,coal gas and noncoke coal powder as fuel and reductant to reduce nodulized ore,block ore and fine ore under solid state.The principle,characteristics,faulty and industrial progress of some typical direct reduction process has been introduced and the developing cause,present state and prospect of the process in the world have been analyzed. |
