Non-Coke DRI HIsmelt Technology refers to a direct reduced iron/hot metal production process based on the HIsmelt smelting reduction process. Its defining characteristic is the complete elimination of coke, enabling the direct use of non-coking coal and iron ore fines to produce high-purity hot metal.
HIsmelt (High-Intensity Smelting) is a direct smelting reduction ironmaking process developed since the 1980s and represents the world's first commercially proven one-step smelting reduction technology. Unlike conventional blast furnace processes, HIsmelt completely eliminates dependence on coke by utilizing pulverized non-coking coal as both reductant and heat source, while directly injecting iron ore fines (<6mm) into the smelting reduction vessel for processing.
Process Description of the HIsmelt Technology
Name Interpretation:
Non-Coke: Eliminates the need for coke, utilizing non-coking coal
DRI: Extension of the Direct Reduced Iron concept
HIsmelt: High-Intensity Smelting
The heart of the HIsmelt technology is the Smelt Reduction Vessel (SRV), see below:

Technology Advantages:
Excellent Raw Material and Fuel Adaptability
The HIsmelt process completely eliminates dependence on coking coal resources, offering significant raw material and fuel flexibility:

HIsmelt |
|
Fuel |
Requires coke (scarce coking coal) |
100% non-coking coal |
|
Iron Ore |
Requires sinter/pellets (8-40mm lump ore) |
Direct use of <6mm ore fines |
|
Refractory Ores |
Poor adaptability |
Suitable for high-phosphorus iron ore, vanadium-titanium magnetite |
|
Solid Waste |
Difficult to utilize |
Can consume up to 15% metallurgical solid waste |
Outstanding Environmental Benefits:
By eliminating coking, sintering, and pelletizing processes, the HIsmelt process delivers significant environmental advantages:
33% Reduction in Carbon Emissions: CO₂ emissions of 0.759t per ton of hot metal, representing a 33% reduction compared to the blast furnace route
Over 15% Reduction in Comprehensive Energy Consumption: Comprehensive energy consumption of 423.5 kgce per ton of hot metal
No Toxic Pollutants: Eliminates the generation of dioxins, furans, tar, and phenols
Particulate Matter Emissions at One-Third of Conventional Levels
Zero Wastewater Discharge & Full Solid Waste Recycling
Superior Hot Metal Quality:
