Manufacturing Process
Raw Material Inspection: High-purity quartz, coke, and low-impurity steel scrap are selected and tested to ensure stable production.
Electric Furnace Smelting: Electric furnace smelting is employed, with temperature and furnace conditions controlled to ensure stable ferrosilicon alloy composition.
Crushing & Screening: Crushing and screening are performed according to customer requirements to control product particle size.
Final Testing & Packing: Finished products are packaged after chemical testing, and a Certificate of Analysis (COA) is provided.
Quality Control
Raw Material Control: Compositional testing of quartz, coke, and steel scrap is conducted to control impurity content at the source.
Production Monitoring: Furnace temperature, smelting parameters, and alloy composition are monitored during production to ensure product stability.
Final Product Testing: Testing includes: Silicon (Si), Aluminum (Al), Carbon (C), Phosphorus (P), and Sulfur (S). A COA is provided for each batch to ensure quality traceability.
