75% fesi powder crushed silicon iron powder

Brief Introduction to 75 Ferrosilicon Lumps   As a significant ferrous additive, 75 ferrosilicon lumps derive their designation from containing roughly 75% silicon. Exhibiting irregular morphology, these non-uniform chunks feature coarse-textured surfaces with a charcoal-gray hue. Characterized by elevated fusion temperatures and inert chemical behavior, they demonstrate minimal reactivity with surrounding elements under ambient conditions, ensuring straightforward storage and transit. Nevertheless, their chemical reactivity escalates within high-temperature settings or aggressive acidic/alkaline media.   Within ferrous metallurgy, 75 ferrosilicon lumps function as dual-purpose deoxidizing and alloying agents, executing oxygen extraction from molten steel while elevating mechanical properties including strength, hardness, and abrasion resistance. In foundry operations, they perform as crystallization modifiers that enhance structural integrity and metallurgical performance in cast comp…
