Sulfur Content Control in the Ladle Furnace Process through Controlling the Pre-desulfurization Time during the Bubbling and Powder Injection Process and Slag Composition in Ladle

Key Points

• The aim is to control sulfur levels in the ladle furnace process by optimizing pre-desulfurization time and slag composition.
• Implemented controlled bubbling and powder injection processes.
• Monitored sulfur, phosphorus, carbon, silicon, and manganese concentrations.
• Assessed the impact of the slag composition on hot brittleness.
• Achieved a significant reduction in sulfur content through optimized pre-desulfurization.
• Demonstrated improved material properties, reducing hot brittleness.
• Found an optimal pre-desulfurization time that effectively managed slag composition.
