Strict Control of Alloy Elements and Harmful Impurities for Stable Performance

2026,06,17
Element proportion and impurity content determine the performance of metallurgical products. For 75# Ferrosilicon, silicon content is stably kept at 72%-78% for efficient deoxidation. Sulfur, phosphorus and carbon are strictly controlled to prevent steel brittleness and welding cracks. We also limit trace elements for welding-grade silicon powder to avoid slag formation. Real-time composition monitoring is adopted during smelting to prevent component segregation. We set differentiated internal standards for mining, steelmaking and welding materials to meet diverse industrial requirements.
