Ferro Silicon 75 Alloy Lumps High Purity For Steelmaking Industry Deoxidizer
Ferro Silicon 75 alloy lumps with high purity are essential deoxidizers in the steelmaking industry, containing around 75% silicon for highly efficient oxygen removal from molten steel. Their elevated purity level minimizes impurities such as carbon, sulfur, and phosphorus, ensuring cleaner steel with improved mechanical properties including strength, ductility, and toughness.
During steelmaking, silicon reacts vigorously with oxygen to form silica, which floats as slag and is easily removed, preventing oxide inclusions that weaken the final product. The lump form provides consistent melting behavior and ease of handling in electric arc furnaces, basic oxygen furnaces, and ladle treatments.
High-purity FeSi 75 is particularly valued in producing high-grade structural, tool, and alloy steels used in automotive, construction, and machinery sectors. Its reliability and performance make it a preferred choice where steel cleanliness and metallurgical precision are crucial. By using this material, steelmakers can shorten refining times, lower slag volumes, and enhance overall process efficiency while meeting stringent quality standards demanded by modern industry.
