Ferro Silicon Alloy With 75 Silicon Content Durable Grey Briquette For Steel Desulfurization​

Ferro Silicon Alloy With 75 Silicon Content Durable Grey Briquette For Steel Desulfurization​


Ferro Silicon alloy with 75% silicon content in durable grey briquette form is highly effective for steel desulfurization processes. The high silicon concentration not only aids in deoxidation but also assists in binding sulfur as silicon sulfide, transferring it into the slag phase and thereby reducing sulfur levels in the steel. Lower sulfur content improves steel’s ductility, toughness, and weldability, which are critical for pipeline, automotive, and structural applications. The briquette format—compressed into dense, uniform blocks—minimizes dust, ensures safe handling, and provides controlled dissolution rates during furnace or ladle treatment. Its grey color indicates a clean, well-processed alloy suitable for precise metallurgical adjustments. Steelmakers benefit from reduced refining time, minimized slag volumes, and enhanced steel cleanliness. This durable briquette form is especially suited for repeated use in high-throughput operations, delivering consistent desulfurization performance and helping manufacturers meet stringent quality benchmarks in sulfur-critical steel grades.
