FASTMET^® PROCESS

FASTMET^® plant to be used as a core or supplemental ironmaking plant in a steel mill

High quality product, with a metallization degree of 85 - 92%, in the form of DRI (Direct Reduced Iron) or HBI (Hot Briquetted Iron), will be charged to Blast Furnace, Basic Oxygen Furnace or Electric Arc Furnace as a core or supplemental source of iron. Carbon content in DRI can be adjusted as per customer's requirement.

DRI can also be melted to produce hot metal (FASTIRON^™) via FASTMELT^® process, which combines RHF with the Electric Ironmaking Furnace (EIF^™) to produce hot metal directly from hot DRI. This method provides an economical source of high purity hot metal and remarkably increases productivity for the succeeding steelmaking process.

FASTMET^® plant to be used as a steel mill waste recycling plant

Steel mill wastes such as BF dust, BF Sludge, BOF dust, Sinter dust, EAF dust, mill scale, and etc., will be processed by FASTMET^® plant. Benefits from this application will be ;

• Elimination of waste disposal cost and landfill liability
• Waste changed to a quality source of iron (DRI)
  • To be recycled in iron or steel making process
    Metallization degree:
    Iron: 85 - 92%
    Nickel: 95 - 100%
• Recovery of Zinc contained in wastes (Zn deriving from scrap)
  • To be sold to zinc producer
    Zinc removal: 95% or higher
• Reclamation of carbon
  
  • Carbon contained in dusts will be used as reductant
  • Carbon content in DRI can be adjusted as per customer's requirement

Kobe Steel, Ltd. also has abundant experiences on environmental matters, such as incinerator and sewerage plants. Experiences on incinerator plant have been adopted to FASTMET^® process facilities, especially to off-gas system. All the environmental restrictions such as particulate, NOx, SOx, dioxin etc. will be cleared as was done in existing FASTMET^® plants.
