| Assured Advantages Lowering Coke rate in the Blast Furnace |
|
| Acticast Chemicals are well established to lower Coke rates in Blast Furnaces by over coming Solution Loss Reaction (SLR) |
| Increases Ore heat absorption & CO Reaction Kinetics |
|
| Increased conductivity to metallic ores, heat up ores faster, lower SLR, ensure BF is always hot. CO Reactivity increases due to Ore receptivity BF becomes more efficient, consuming lower Energy / THM |
| Targets lowering Direct Reduction Reaction (DRR & SLR) |
|
| Acticast targets the floor conditions CO2 + C reaction to complete within the Tuyere Zone. Unreacted CO2 from Tuyere is lowered to bare minimum. DRR lowers, reducing thermal load in the system, along with lower SLR. More Carbon reaches the Tuyere due to lower SLR & DRR, lowering coke rate & energy consumption in the BF |

| Dosage Information |
|
| Acticast dosing is upon Metallurgical in prescribed dosages by spraying upon Coke & feed it BF |
| Dosage 3 to 5 Kg / MT Coke (Higher the CRI, higher is the dosage) |
|
|
|
|
|
| (Pre-requisites for Acticast Tests) |
| Performance under identical Coke & Ore quality |
| Dosing labor to be made available |
| The BF tends to become very hot due to lower SLR & DRR, BF to increase ore load & avoid steam injection |
