Steel Making Additive
Steel Making Additive – Aluminium Ash for the Steel Industry
Aluminum ash is used in steel making and provides various benefits such as improved yield and quality. It has various applications depending on the aluminium content, feeding method, and timing.
We mainly handle aluminium ash with 30-50% aluminium content. Please contact us for other content ratios.
Usage of Aluminium Ash in the Steel Industry
| Purpose | Effect | Advantage |
|---|---|---|
| Deoxidizer | Deoxidizer Metallic aluminium reduces iron oxide and improves the yield of iron. | Yield Increase |
| Exothermic Agent | The heat generated by the oxidation reaction of aluminum is used as an auxiliary heat source for scrap melting. | Energy Efficiency Improvement Reduction of Cost Reduction of CO2 Emissions |
| Slag Reforming Agent | Reduce free CaO in steel slag to stabilize and make it easier to process slag into roadbed material. | Slag Stabilization |
| Forming Accelerator | The slag is bubbled, and the electrodes are buried within it, increasing the arc discharge’s heat transfer efficiency. This setup prevents heat from being transferred directly to the furnace wall, thereby extending the life of refractory materials. | Energy Efficiency Improvement Longer Refractory Life Reduction of Arc Flare |
| Insulation Compound | It is added to cover the surface of molten steel during casting, helping to prevent heat loss, optimizing the smelting process and preventing oxidation. | Reduction of Cost Steel Quality Improvement |
| Smelting Flux | The reaction of CaO with Al2O3 in aluminium ash produces slag, which promotes the interaction between slag and molten steel. | Steel Quality Improvement |
