Ferro Silicon 75%Lump-Blast Furnace Grade

Ferro Silicon 75% Lump – Black Furnace Grade (FeSi75 Furnace Lump) is supplied for direct furnace charging in EAF, induction furnace and cupola operations. With Si ≥75% min and naturally crushed dark-grey/metallic lump form, it provides strong deoxidizing power and silicon alloying at lower cost than bright-finished grades. Uniform lump size and controlled fines reduce dust loss during bin feeding—ideal for steel plants and foundries needing economical, stable furnace-grade FeSi for bulk addition and Si adjustment.

Product Description

1.Cost-Effective Furnace Charging Grade – "Black Furnace Grade" means naturally crushed unpolished lumps for direct furnace feed, priced lower than bright-finished alloy-suited to high-volume EAF/induction furnace/cupola users.

Higher Si = Less Alloy per Heat – Si ≥75% delivers stronger deoxidizing and Si-contribution than FeSi65/72, reducing total addition weight.

Low Fines, Less Dust Loss – Screened lump with controlled fines ratio (typically ≤3–5%), minimizing dust in weigh hoppers and improving recovery.

Versatile Furnace Use – For in-furnace deoxidation, bulk Si alloying, and as base material for foundry inoculation (Low-Al version available on request).

Batch COA & Inspection Supported – Each lot ships with COA; pre-shipment SGS/BV inspection arranged upon request.

Main Applications

1.In-furnace deoxidation & Si alloying for steelmaking (EAF/BOF charge)

2.Si adjustment and inoculant base material in iron foundries (cupola/induction)

3.Reducing agent in Pidgeon-process Mg smelting

4.Silicon source for downstream ferroalloy production

Packing & Customization

1.Std: 1MT UV jumbo bag with PE moisture barrier

2.Options: 25kg×40 in big bag / palletized / custom marks

3.Size range, Al/Ca limits & lump grade can be tailored to your furnace practice

4.SGS/BV/CCIC pre-shipment inspection & loading photos provided

Higher Al Content Suited to Foundry & Mg Smelting – Al ≤2.5–3.0% makes this grade well suited to iron foundry inoculation and Pidgeon-process magnesium reduction, where Al is acceptable or even beneficial-no extra cost for unnecessary low-Al specs.

Full Element Disclosure – Mn, Cr and Cu levels are declared upfront, eliminating surprises from undocumented tramp elements that could affect your melt chemistry.

Furnace-Grade Tolerance = Better Pricing – A practical 72–78% Si range reflects real-world lump variability without paying for tight-tolerance finishing-ideal for cost-conscious bulk buyers.
