Steel Mill Scrap Processing: Best Practices and Equipment Selection
Comprehensive guide to handling mill scrap safely and efficiently with industrial-grade processing equipment.
Steel mill scrap processing requires specialized equipment and procedures to handle high-temperature materials, heavy sections, and demanding production schedules. This guide covers essential best practices for safe, efficient mill scrap handling and the equipment selection criteria for optimal performance in steel mill environments.
Types of Mill Scrap
Hot Mill Scale
Iron oxide scale produced during hot rolling operations, typically 2-5% of steel production.
- • High temperature (300-800°C)
- • Abrasive properties
- • 60-70% iron content
- • Fine particle size
Crop Ends & Cobble
Steel sections cut from production ends and processing irregularities.
- • Large, irregular shapes
- • High steel quality
- • Minimal contamination
- • Processing priority material
Turnings & Borings
Machining waste from steel finishing operations and maintenance activities.
- • Oil contamination
- • Small particle size
- • Requires cleaning
- • Good steel grades
Structural Returns
Heavy structural sections from maintenance, demolition, and production modifications.
- • Large, heavy sections
- • Requires size reduction
- • Known steel chemistry
- • High furnace value
Safety Considerations
