Furnace Scale – High Fe, Low Moisture, Graded Mill Scale for Metallurgical Applications

We supply and export furnace scale and mill scale lumps from India for international metallurgical and mineral-processing buyers. This ferrous scale material is a dense iron oxide by-product widely used in sintering, briquetting, smelting, and cement kiln applications. Our shipments typically consist of industrial mill scale in screened and graded form, including steel scale lumps and other dense fractions suitable for bulk industrial use. Buyers sourcing mill scale export grade or high-Fe furnace scale generally require predictable chemistry, stable physical form, and reliable shipment preparation, which we support through inspection, grading, and export documentation. Material is available in controlled size ranges such as 0–10 mm and 10–50 mm, with stable Fe content, low impurity levels, and controlled moisture for reliable metallurgical performance. We work with international buyers requiring consistent quality, uniform size distribution, and predictable bulk density for industrial processes. Lots are inspected and prepared to meet technical suitability for sinter feed, induction furnace use, and other high-temperature processes, ensuring compatibility with standard metallurgical blends and handling requirements.

Technical Specifications (Typical Commercial Ranges)

Actual values vary by lot and buyer specification; detailed test reports are shared prior to shipment.

Typical composition and physical characteristics:

• Content (Fe total): commonly supplied as high Fe mill scale or furnace scale with stable Fe content, typically in commercially accepted industrial ranges

• Moisture: supplied as low moisture mill scale or mill scale with controlled moisture level, depending on storage and handling conditions

• Density: supplied as mill scale high density or heavy density mill scale bulk lots where higher bulk density is required

• Impurities: selected lots may meet requirements for low impurity mill scale for smelting or mill scale bulk with low gangue

• Physical consistency: available as consistent mill scale, screened mill scale, or graded mill scale depending on buyer specifications

Material may be supplied as furnace scale lumps, fines, or blends according to downstream processing requirements.

Size Range and Grading

We arrange screening and grading according to end-use requirements and handling tolerances. Typical commercial sizes include:

• Mill scale 0-10mm or screened mill scale 0 to 10 mm for blending or pelletizing

• Mill scale 10-50mm or furnace scale lumps 10 to 50 mm for bulk metallurgical charging

• Custom grading to meet furnace scale with uniform size distribution and graded furnace scale for sinter feed

Where required, lots may be prepared to meet furnace scale meeting bulk handling tolerance or plant-specific feed specifications.

Quality and Inspection

Quality control focuses on commercial usability and consistency rather than laboratory-grade refinement.

Inspection and verification typically include:

• Visual and physical inspection for mill scale bulk with minimal rust fines

• Sampling to confirm high iron content mill scale bulk orders meet agreed parameters

• Verification of furnace scale with consistent bulk density and handling characteristics

• Independent surveyor inspection when required for furnace scale bulk for metallurgical plants

This approach helps ensure shipment reliability and predictable performance in downstream processes.
