DRI
Natural gas Smelter
Hot liquid iron • Two-staged process: DRI production + smelting • Smelting releases coal-based gas, which is used as a reducing agent in shaft furnace
Note: Smelting reduction: reduction: Coal directly used as reducing reducing agent, process as substitute of BF; Direct reduction: reduction: Gas as reducing agent, even gasification gasification of coal, product used as input in EAF Source: Lockwood Lockwood Greene; IEA Clean Coal Center; Rio Tinto Tinto Hismelt website; Siemens Siemens VAI website; BCG analysis 240682-86-Iron and Steel industry-Final report-29May12-vf.pptx report-29May12-vf.pptx
