Inoculante da fonderia (FeSiBa)

FeSiBa

Foundry inoculant (FeSiBa) is a barium-bearing ferrosilicon added to molten grey and ductile iron just before or during pouring. The Si carrier and 1-3% Ba seed silicate-oxide nuclei in the melt, giving graphite a preferred site to precipitate as the iron solidifies. This suppresses undercooling, cuts the chill (white iron) tendency at thin sections and edges, and refines graphite morphology toward a fine, evenly distributed Type A flake in grey iron or a higher nodule count in ductile iron. The 1-2% Ca and ≤1.5% Al support deoxidation and keep nucleation active longer, reducing fade in held or transferred metal. Used for grey iron inoculation, ductile iron inoculation, chill reduction and graphite refinement across automotive and machinery ductile-iron foundries and general jobbing shops. Typical late/ladle addition runs about 0.1-0.5 wt% (1-5 kg/t); finer 0.2-0.7 mm sizing suits in-stream or in-mould dosing, while 1-3 mm fits ladle treatment. Supplied with COA and MTC against ISO/ASTM practice, multi-regional sourcing, CIF Marmara or Gebze bonded stock, 20 MT FCL. Send grade, size and tonnage for an RFQ.
