Chemical Composition
Elemental breakdown by percentage weight.
Standard composition limits
Values represent maximum allowed percentage unless otherwise noted.
Physical Properties
Material form, density, and contamination specifications.
Value-added processing of steel turnings through mechanical compression; increased density enables efficient melting; primary application briquettes for furnace feeding
Acceptable Inclusions
- Oil residue <3% (inherent; compression aids drying)
- Coolant residue <1.5%
- Fine iron oxide from processing
- Dust from compression process
Prohibited Materials
- Copper contamination >0.15%
- Stainless steel chips (segregation)
- Non-ferrous >0.5% individual
- Synthetic polymer residue (from coolant)
- Radioactive materials
- PCB or hazardous electronics
- Asbestos materials
- Mercury components
- Excessive oil >3.5% (indicates incomplete drying)

- consistent compression
Procedure
- Sample measurement
- bulk weight calculation
XRF Spectrometry
Purpose
- Verify Fe ≥95%, C <0.35%, Cu <0.15%
Acceptance Criteria
- Pass: Fe ≥95%, C acceptable, Cu <0.15%
Briquette Integrity Assessment
Purpose
- Verify briquettes intact
- resistant to breakup
Acceptance Criteria
- Pass: No crumbling, breakage, or dust loss during handling
Procedure
- Drop/handling test on representative briquettes
