1. Product Overview

Ferrosilicon Cored Wire, simplified as FeSi Cored Wire in cross-border metallurgical orders, is economical universal Foundry Inoculant Wire developed for medium and small grey iron casting factories, serving as standard Ladle Grain Refiner Wire, mainstream Cast Silicon Wire Feed and general Grey Iron Modifier Wire for mass production of medium-thickness grey iron hardware, pipes and agricultural machinery parts. Different from magnesium, calcium and barium multi-element cored wires with multiple functions, this single silicon wire only focuses on graphite homogenization and eliminating cementite white edge defects, featuring obvious cost advantages for mass low-demand casting lines. Low-carbon steel thin strip forms the outer sealed shell, filled with graded industrial silicon powder processed via closed crushing and screening craft, avoiding powder leakage during continuous automatic wire feeding. Zemei's standard silicon formula keeps silicon content stable at 70–75%, strictly controlling aluminum upper limit to reduce secondary gas generation risk of medium-thick castings. After being fed into 1400–1490℃ grey iron liquid, silicon element releases massive heterogeneous crystal nuclei within short time, the effective grain refining period lasts 8–14 minutes, perfectly matching discontinuous pouring rhythm of small foundries with short molten iron retention time. It can be used independently for ladle late inoculation, or matched with silicon-barium wire to assist grain refinement while removing pinholes, cutting grey iron white spot reject ratio by more than 16%. All finished reels pass filling uniformity inspection before shipment, SGS component test certificates can be provided to overseas small casting factory customers for customs clearance and supplier assessment. The factory's single silicon wire production line supports customization of silicon content, wire diameter and single reel loading weight.

2. Raw Material & Standard Production Flow

Core filling medium of FeSi Cored Wire is high-purity industrial silicon ingots, crushed and two-layer vibration screening to filter excess floating fine dust that easily leads to pipeline blockage during wire feeding. Outer steel belt thickness 0.3–0.5mm melts quickly inside molten iron without generating large slag mass to interfere casting surface quality. The whole production workshop adopts closed dust recovery system and automatic fixed-volume powder feeding devices, maintaining stable silicon content of each batch of core powder without inoculation fluctuation caused by manual proportion deviation. Complete standardized manufacturing sequence: High-purity silicon crushing → double-layer impurity screening → magnetic separation metal foreign matter → quantitative powder conveying → steel strip U forming → continuous silicon powder filling → bilateral cold sealing → wire diameter sizing → automatic reel winding → grey iron inoculation simulation test → moisture-proof export wrapping. All waste gas and dust are fully purified to meet domestic and overseas environmental supervision rules. This Ladle Grain Refiner Wire keeps stable grain refining effect for 8–14 minutes after entering liquid iron, effectively relieving white edge and coarse graphite defects brought by delayed casting. Standard reels are permanently stocked in constant-temperature warehouses, full-container shipments can be finished within 7–10 working days after prepayment arrival.

3. Fixed Chemical & Custom Wire Sizes

Stable core silicon index: Si 70–75%, Al ≤1.5%, S ≤0.04%, P ≤0.03%. Two adjustable formulas: standard low-aluminum type for general grey iron, ultra-low aluminum customized version for thin medium-thickness castings. Optional outer wire diameters: 9mm, 10mm, 12mm. Standard single reel weight: 250kg, 500kg, 1000kg. All reels are fixed on fumigation-free timber pallets with stretch film, desiccant bags added to resist ocean dampness and silicon powder oxidation. Each batch is attached with full English COA record of silicon content and filling ratio. Trial coils starting at 50kg are acceptable, sample cost can be fully offset in subsequent bulk cooperation. Custom items include silicon fine-tuning, wire diameter change and pallet LOGO printing service.

Six Unique Product Advantages (No cross-file repetition)

Ultra-low comprehensive cost of Ferrosilicon Cored Wire

Single silicon component without expensive rare earth/calcium/barium elements, the most economical inoculation wire for mass grey iron production.

Stable grain refining capacity of Foundry Inoculant Wire

Generates abundant crystal nuclei to eliminate white hard edges and coarse graphite clusters of medium-thick grey iron.

Short anti-fading window matching small factories

Valid refining time 8–14 minutes, suitable for short molten iron holding production mode without redundant performance waste.

Smooth wire feeding performance of Ladle Grain Refiner Wire

Double-layer screening lowers floating powder, prevents automatic feeder pipeline blockage.

Mild melting trait of Cast Silicon Wire Feed

No violent liquid iron splashing during wire feeding, lower molten loss and higher operation safety.

Wide multi-process compatibility of Grey Iron Modifier Wire

Three wire diameters fit all domestic and imported automatic wire feeders without equipment transformation.

5. Global Target Application Fields

This FeSi Cored Wire mainly supplies medium and small grey iron foundries in more than 18 overseas regions, covering three major downstream sectors:

Municipal medium-thick grey pipe fittings

Conventional water supply and drainage cast pipes; Middle East small pipe factories select 10mm standard coils.

General hardware grey iron castings

Valve bodies, pipe joints, mechanical support frames; Southeast Asian hardware foundries adopt standard low-aluminum formula.

Light agricultural machinery castings

Low-load shell and tool parts; South American agricultural foundries use combined wire feeding with silicon-barium wire. When matched with ferrosilicon barium cored wire, it realizes grain refinement and degassing at the same time, significantly reducing surface hard spot defects of grey iron castings, and has been widely adopted by small and medium casting manufacturers all over the world.

Zemei maintains stable bulk supply to grey iron factories in Vietnam, Thailand, Poland and other countries, and provides free silicon formula adjustment for long-term customers.
