Silicon Calcium Barium Cored Wire | Multi-Element Composite Anti-Pinhole Inoculant Wire from Zemei Factory
1. Product Overview
Silicon Calcium Barium Cored Wire, also named Barium Calcium Silicon Cored Wire and shortened as SiCaBa Cored Wire in global precision casting markets, is a high-performance composite Foundry Multi-Element Inoculant Wire integrating grain refinement, molten iron purification, deoxidation and anti-pinhole functions, also widely used as professional SiCaBa Wire Feed and exclusive Casting Anti-Pinhole Cored Wire for thin-wall precision ductile iron and gray iron foundries. Jiaocheng Zemei Metal Co., Ltd. independently develops and produces this three-element composite cored wire relying on our 20-year ferroalloy smelting experience and fully automatic wire forming workshops, making up for the single function defect of single silicon barium or silicon calcium wire which cannot simultaneously solve grain coarsening, pinhole and shrinkage porosity defects. Silicon inside provides massive heterogeneous crystal nuclei to refine grains, barium absorbs oxygen and nitrogen impurities to eliminate pinholes, calcium deepens deoxidation and desulfurization, three elements work synergistically to realize one-time composite inoculation purification treatment, greatly improving thin-wall casting finished product rate.
This product adopts 0.3–0.6mm low-carbon cold rolled steel strip as outer protective shell, filled with uniformly graded silicon-calcium-barium alloy powder inside, sealed through continuous double-edge cold rolling without powder leakage. When fed into molten iron at fixed speed via automatic wire feeder, the steel sheath melts at preset depth under liquid surface, releasing silicon, calcium and barium elements deep inside the molten bath. Silicon first forms tiny crystal nuclei, barium reacts with dissolved gas to generate floating slag, calcium removes residual sulfur and oxygen, forming a complete molten iron purification system. As dedicated Casting Anti-Pinhole Cored Wire for new energy auto thin-wall castings, precision hydraulic parts and medical ductile iron components, it can be used independently for late stream inoculation or matched with FeSiMg nodulizer cored wire for synchronous double-wire composite treatment. All batches of Silicon Calcium Barium Cored Wire comply with international precision casting auxiliary material standards, each coil passes air tightness, filling uniformity and tensile strength test before delivery, supporting SGS, BV third-party full element inspection to meet overseas foundry audit and customs clearance requirements.
2.Raw Material & Production Process
Core filling material of SiCaBa Cored Wire is self-smelted silicon-calcium-barium composite alloy block, refined through secondary purification smelting to control free aluminum and harmful trace elements at ultra-low levels; after crushing, materials go through three-stage vibration screening to remove superfine dust that causes wire leakage during high-speed winding, only medium uniform particles are reserved for filling. Low-carbon steel strip features low melting point, no residual hard slag after melting, and will not introduce new impurities to contaminate molten iron quality.
Complete standardized production flow: silicon calcium barium alloy crushing → three-layer vibration grading → magnetic separation iron scrap removal → constant volume quantitative powder supply → steel automatic uncoiling → U-shaped cold rolling forming → continuous uniform filling → bilateral airtight cold seal → fixed wire diameter sizing → automatic coil winding → coil bundling → finished performance inspection → moisture-proof film export packaging. Real-time weight sensors are installed on each filling station to control powder filling tolerance within ±1.2%, ensuring consistent anti-pinhole and grain refining performance of every coil of Barium Calcium Silicon Cored Wire. The closed flue dust removal system fully meets international environmental protection standards, satisfying overseas buyers with strict factory environmental audit requirements. As high-value SiCaBa Wire Feed, its effective purification & inoculation retention time reaches 10–14 minutes after adding into 1420℃–1500℃ molten iron, perfectly matching long-transfer thin-wall casting lines. Our factory maintains permanent large stock of standard SiCaBa Cored Wire all year round, bulk orders delivered within 7–12 working days.

8. FAQ
Q1: Difference between SiCaBa and single SiBa/SiCa wire?
A1: SiCaBa integrates grain refining, deoxidation and anti-pinhole, single alloy wire only has single function, cannot handle ultra-thin castings.
Q2: Suitable casting wall thickness?
A2: Best for 3–6mm thin wall, ultra-low Al custom version fits <3mm ultra-thin parts.
Q3: Can match nodulizer cored wire?
A3: Yes, double wire feeding equipment supports synchronous delivery.
Q4: Export documents available?
A4: English COA, MSDS, SGS report, ISO certificate, pallet fumigation certificate, invoice & packing list.
