Rolling Mill Scale – High Fe, Low Moisture, Metallurgical Grade for Global Buyers

Rolling mill scale is an iron-rich by-product generated during hot rolling of steel and widely reused in metallurgical and recycling operations. As an exporter serving international buyers, we handle rolling mill scale in the form of mill scale lumps and mill scale powder, prepared to meet commercial and technical requirements in global trade. Material is selected and graded to provide high Fe mill scale with low moisture, suitable for sintering, pelletizing, briquetting, and furnace charging. Buyers sourcing furnace grade mill scale require consistency in chemistry, size distribution, and moisture to ensure stable process performance. Uniformly sized lumps and fines are screened to maintain tight size tolerance, low impurity levels, and consistent quality required in metallurgical operations. The material is suitable for blast furnace charge, electric arc furnace processes, and sinter plants where stable Fe range, magnetic content, and controlled moisture are important. Prepared for recycling, smelting, and metal recovery applications, the material is graded for uniformity, bulk density consistency, and technical suitability, and can be evaluated for magnetic response when required.

Technical Specifications

Typical commercial ranges may vary by lot and buyer specification, but industrial buyers generally expect:

• Typical Fe content: 65–72% (high iron content rolling mill scale)

• Moisture range: 1–5% depending on storage and handling (rolling mill scale with low moisture preferred)

• Oil and impurity levels: Low impurity rolling mill scale material suitable for metallurgical use

• Form: Lumps, fines, or powder

• Bulk density: Stable and consistent quality rolling mill scale material suitable for furnace feeding

Material can be screened or blended to meet rolling mill scale meeting metallurgical grade requirements where required by downstream users.

Size Range and Grading

International buyers often specify controlled sizing to ensure predictable furnace or sinter bed behavior.

Common commercial grading includes:

• Uniformly sized rolling mill scale lumps (for furnace charge or sintering)

• Rolling mill scale fines for briquetting or pellet feed

• Screened rolling mill scale for sintering to maintain permeability and mix uniformity

Where required, material can be supplied as:

• Rolling mill scale with tight size tolerance

• Dry rolling mill scale ready for use in handling or blending operations

Quality and Inspection

Quality control is important for buyers using mill scale in thermal or metallurgical processes.

Inspection parameters typically include:

• Fe content verification

• Moisture measurement

• Size distribution analysis

• Visual inspection for contamination

• Magnetism where magnetic rolling mill scale high Fe is specified

Pre-shipment inspection and documentation can be arranged according to buyer requirements, ensuring consistent quality rolling mill scale material across shipments.

Applications and Industry Use

Rolling mill scale is widely used in the following sectors:

Metallurgical and steel industries

• Rolling mill scale for blast furnace charge

• Rolling mill scale for electric arc furnace

• Rolling mill scale compatible with sinter plants

Metal recovery and recycling

• Briquetting and pelletizing

• Smelting and iron recovery

Foundries and ferroalloy operations

• Charge material blending

• Flux and reductant mixtures

Operational use typically requires:

• Stable Fe range

• Controlled moisture

• Predictable melting or reduction behavior

Technical Suitability and Performance Expectations

Industrial users generally expect:

• Good compatibility in sinter mixes and pellet feeds

• Predictable reduction characteristics in furnaces

• Stable handling properties in bulk storage

• Minimal dust generation when moisture is controlled

Material prepared as rolling mill scale suitable for pelletizing or screened rolling mill scale for sintering helps maintain process stability, bed permeability, and furnace efficiency.

In furnace applications, rolling mill scale with low moisture and uniform grading reduces variability in thermal balance and material flow.

Packaging and Logistics

Rolling mill scale for export is typically shipped in:

• Bulk vessel shipments

• Jumbo bags (FIBC)

• Loose container loading where appropriate

Handling practices include:

• Protection from excess moisture during storage and loading

• Shipment readiness checks before dispatch

Ports of loading, containerization, and bulk handling methods are coordinated based on shipment size, Incoterms, and buyer destination.

Storage and Handling Considerations

Industrial buyers typically store mill scale under:

• Covered storage to control moisture

• Segregated stockpiles by size fraction

• Proper drainage to avoid water accumulation

These measures help preserve dry rolling mill scale ready for use and maintain material consistency during processing.
