G. Iron and steel, and other metallurgical projects –
1. Gas Oxygen Refiner (GOR) to make high quality carbon steels, alloy steels and stainless steels, and also to refine steels from Induction furnaces.
2. Ladle desulphurization technology, using 100% granulated magnesium in iron and steel making units.
3. DC arc furnace with a bottom electrode, for efficient melting of non- conductive materials like sponge iron and other metallurgical wastes.
4. Reduction of iron ore briquettes / titaniferous magnetite ores into DRI in third generation tunnel kilns; reduction of steel mill scale into metal powders by tunnel kiln + hydrogen reduction process.
5. Carbon composite briquetting; DRI and steel production in the Rotary hearth furnace + mini blast furnace, or in the Rotary hearth furnace + electric arc furnace routes.
6. Ferro chrome making plant (high-carbon and medium-carbon), using chrome ore fines + coke fines, by oxygen melting in the GOR + Induction furnace route (without the need for power-intensive submerged arc furnaces).
7. Production of chrome-containing pig iron and manganese-containing pig iron in mini-blast furnaces for direct production of 200 series (utensil grades) stainless steels.
8. Granulated magnesium making project.
9. Technology for using non-coking coals up to 80% in stamp-charged coke oven plants.
10. Metallic electrodes to replace graphite electrodes, in steel refining.
11. Vertical grinding mill to make ground, granulated blast furnace slag (GGBS) on a large scale.
12. Rock wool making plant to utilize blast furnace slag; corrugated roofing steel + rock wool sandwich panel making plant for outdoor thermal insulations (container homes and insulated factory buildings).
13. Direct crushing of converter liquid slags into 50 – 600 mm sized stones for road construction, with capacities up to 300 tons per hour.
14. Centrifugal separation of fly ash, to recover ultra-fine fly ash particles for cement making.
15. Coke – free production of pig iron / cast iron, using iron ore fines, blast furnace and steel mill wastes, and tailings from iron ore beneficiation plants.
16. Conversion of sponge iron making plants into pig iron making plants, while doubling their capacities.
17. Simultaneous recovery of iron and cement clinker from steel mill slags of electric arc furnace / converter.
18. Oxygen melting of low grades of nickel, copper, tin, zinc and lead ores, to recover non-ferrous metals.
