Steel Mill Dust

Description

1. Product Overview
Steel Mill Dust is a high‑purity by‑product recovered from the steelmaking furnace off‑gas stream, processed into a fine, free‑flowing powder. It serves as a valuable raw material for cement, concrete additives, and metallurgical fluxes, delivering a cost‑effective source of iron oxide and alumina. Its strategic value lies in turning waste into a revenue‑generating input, supporting circular‑economy goals while reducing raw‑material procurement costs for heavy‑industry manufacturers.

2. Key Specifications & Technical Characteristics

Chemical Composition (typical range):

Fe₂O₃ … 42‑48 %
SiO₂ … 15‑22 %
Al₂O₃ … 5‑9 %
CaO … 2‑5 %
MgO … ≤1 %
Trace elements (Mn, Ti, etc.) within regulatory limits

Purity / Grade: Premium Grade – ≥ 95 % total metal oxides, low combustible carbon (< 0.5 %).

Physical Characteristics:

Form: Fine granular powder (free‑flowing)
Color: Light to medium gray, homogeneous
Particle size: 75 µm – 200 µm (99 % passing 200 µm)
Bulk density: 0.85 – 0.95 t/m³ (loose)

Packaging Options:

Bulk bulk‑truck (up to 20 MT per load)
20‑ft / 40‑ft ISO containers with moisture‑proof liners
Optional on‑site storage silos (custom engineered)

Shelf Life: Stable under dry conditions; indefinite when stored in moisture‑controlled environment.

3. Core Industrial Applications

Cement & Concrete Industry

Used as a pozzolanic additive to improve early‑strength gain and reduce clinker factor.
Enhances grindability of cement clinker, lowering energy consumption in milling.

Steelmaking & Foundry Fluxes

Provides iron oxide and alumina for ladle fluxes, promoting slag fluidity and impurity removal.

Road Construction & Asphalt Stabilizers

Acts as a mineral filler that improves load‑bearing capacity and durability of base courses.

Environmental Remediation

Captures heavy metals in soil stabilization projects, offering a low‑cost binding agent.

Why it outperforms alternatives:

Higher iron‑oxide content than conventional fly ash, delivering superior reactivity.
Lower carbon footprint – reuse of process waste eliminates additional mining.
Cost advantage – typically 30‑40 % cheaper than virgin raw materials on a per‑ton basis.

4. Competitive Advantages

Quality Consistency: Strict on‑line monitoring ensures batch‑to‑batch uniformity within ±2 % on key oxides.
Supply Reliability: Direct tie‑ins with major steel plants guarantee continuous availability 12 months/yr.
Logistics Capability: Dedicated bulk‑handling fleet and global containerized shipping network support rapid lead‑times (≤ 21 days from order).
Price Competitiveness: Tiered pricing model rewards volume commitments; transparent cost structure with no hidden surcharges.
Sustainability Credentials: Certified under ISO 14001; contributes to client ESG targets by diverting waste from landfills.
Technical Support: Full data‑sheet package, safety data sheet (SDS), and on‑site application assistance from metallurgical engineers.

5. Commercial & Supply Information

Minimum Order Quantity (MOQ): 20 MT (bulk)
Bulk Loading Capacity: Up to 20 MT per container (standard 40‑ft) or equivalent truckload per shipment
Payment Terms: LC at sight, T/T 30 days, or negotiated escrow based on volume
Delivery Lead Time: 14‑21 days after order confirmation, subject to shipping lane availability

Strategic sourcing of Steel Mill Dust enables manufacturers to lower input costs, meet sustainability commitments, and secure a reliable supply of high‑performance mineral additives.
