Ferrosilicon Barium Cored Wire | Anti-Pinhole Barium Silicon Inoculant Wire from Zemei Factory

1. Product Overview

Ferrosilicon Barium Cored Wire, abbreviated FeSiBa Cored Wire in cross-border casting trade, is dedicated Anti-Blowhole Cored Wire independently developed for thin-wall grey iron and vermicular iron foundries, functioning as exclusive Thin Wall Cast Wire Feed, efficient Molten Iron Degasifier Wire and special Vermicular Iron Inoculant Wire integrated with degassing + grain refining dual effects. Ordinary single silicon cored wire cannot absorb hydrogen and nitrogen dissolved inside liquid iron, leading to high pinhole reject ratio of thin castings; calcium/magnesium wires lack long-term degassing performance for long-time holding molten iron. This FeSiBa wire takes silicon-barium composite alloy as core filling material, low-carbon steel strip forms airtight outer wrapping via continuous cold pressing, effectively preventing fine powder leakage during high-speed wire feeding. Zemei's R&D team adjusts barium proportion according to casting wall thickness, developing low, medium, high barium three formulas matching different thin-wall working conditions. After wire feeding into 1400–1480℃ liquid iron, barium component captures gaseous impurities to form floating slag, silicon generates massive crystal nuclei, the valid dual-function window reaches 20–25 minutes, solving pinhole and coarse graphite defects of automated foundries with intermittent pouring. It can be used alone for ladle late inoculation, or matched with ferrosilicon magnesium wire for composite wire feeding to realize degassing + spheroidization integrated treatment, lowering thin-wall casting scrap rate by over 21%. All finished reels pass filling uniformity and air tightness test before delivery, SGS full-element test papers can be supplied for overseas thin-wall casting factory customs clearance and audit. The factory's special barium alloy wire line supports customization of barium content, wire diameter and single reel weight.

2. Raw Material & Complete Automated Production Process

Core filling medium of FeSiBa Cored Wire is self-smelted silicon-barium alloy ingots, after water quenching crushing, multi-layer vibration screening removes superfine powder easy to leak. Outer steel belt thickness controlled 0.3–0.5mm, melting speed mild without forming thick slag layer to block ladle wire feeding equipment. The whole production line is equipped with fully enclosed dust recovery and constant-volume automatic powder conveying system, stabilizing silicon-barium ratio of each batch core material and eliminating degassing effect fluctuation caused by manual batching error. Full standardized manufacturing flow: SiBa alloy crushing → multi-layer impurity vibration screening → magnetic separation oxide foreign matter → quantitative constant volume powder delivery → steel strip U forming → continuous core filling → bilateral cold airtight crimping → wire diameter sizing → automatic reel winding → thin-wall pinhole simulation test → moisture-proof film export packing. All flue gas and dust are circulated for purification, meeting global metallurgical environmental standards. This Molten Iron Degasifier Wire keeps stable degassing and grain refining effect for 20–25 minutes after entering liquid iron, perfectly coping with long molten iron waiting cycle of large automated workshops. Standard coils are permanently stocked in constant-temperature dry warehouses, full-container sea shipments can be finished within 7–12 working days after prepayment confirmation.

3. Fixed Chemical & Custom Wire Specifications

Stable core element range: Si 65–72%, Ba 3–8%, Al ≤1.2%, S ≤0.03%, P ≤0.03%. Three adjustable formulas: low barium for wall thickness 8–12mm, medium barium standard for 4–8mm thin castings, high barium ultra-low aluminum for castings thinner than 4mm. Optional outer wire diameters:9mm,10mm,12mm,13mm. Standard single reel weight:250kg,500kg,1000kg. All reels fixed on fumigation-free timber pallets with stretch film, desiccant bags placed inside pallets to avoid barium oxidation during ocean transportation. Each shipment attached full English COA recording barium content and filling ratio. Trial coils starting at 50kg are acceptable, sample payment fully deductible in subsequent bulk orders. Customizable items include barium fine-tuning, wire diameter modification and pallet brand LOGO printing.
