FASTMET PROCESS

FASTMET® is a direct reduction process using rotary hearth furnace (RHF).
Various carbon sources such as coal, coke breeze or carbon bearing wastes can be used as reductant. Reduction process is completed in 6 - 12 minutes.

Application

Ironmaking from iron ore

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^TM) via FASTMELT® process, which combines RHF with the Electric Ironmaking Furnace (EIF^TM) 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.

Recycling of steel mill wastes

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
