Fast-Melting Dual-Use Silicon Pellets | Universal Silicon Grain For Foundry Modification & Steel Ladle Deoxidation

1. Product Brief

This series of silicon pellets is designed for dual metallurgical scenarios of casting graphite adjustment and molten steel deoxidation, the core competitive advantage lies in ultra-fast melting speed compared with bulk silicon ingots. Most irregular silicon grit on the market carries over 10% ultrafine floating powder, which will generate massive oxidation loss once contacting high-temperature molten metal; our multi-stage closed screening technology limits excess fine dust below 5%, maximizing silicon utilization efficiency both in iron and steel liquid. Five complete silicon grades ranging from 60# to 75# are available to match different metallurgical cost standards, no barium or calcium rare earth extra additives are mixed inside the raw material formula, focusing purely on silicon's melting and oxygen removal functions. The product does not carry specialized pore elimination or long-term anti-fading performance, so it is suitable for factories with standard molten metal quality without severe thin-wall blowhole or long heat preservation demands. Zemei Metal's 10,000㎡ production base owns complete medium-frequency melting lines and automatic granulating equipment, annual output reaches 35,000 tons, supporting 1-ton trial mixed orders and full 25-ton FCL shipments. All waste gas and dust processing equipment runs 24 hours to meet international industrial emission limits. The pellets serve two major industries simultaneously: grey/ductile iron foundry and carbon steel refining plant, covering auto casting, municipal pipes, general steelmaking ladle deoxidation and composite ferroalloy raw material production. We have complete ISO triple certifications, each batch provides SGS test data and factory certificates for cross-border customs clearance.
