Innovative technologies for improved management of chemicals and oils at Stelco`s Hilton Works cold mill
- Stelco Inc., Hamilton, Ontario (Canada). Hilton Works
Stelco`s Hilton Works has in place a 3-year plan to reduce environmental liability and cost at its cold mill. A blueprint of all liquid wastes generated in the cold mill identified alkali cleaners as a prime candidate for recycling. A novel alkali recycling process has been developed and is now operating at two cleaning lines. Similarly, a proprietary method of recycling hydraulic oils from mill pits for reuse as prime product has been developed. Further studies are under way to recycle tandem rolling mill detergents. Innovative technologies are also being applied to the removal of particulates (irons, wood chips and mill dirt) from tandem mill rolling solutions and detergents. These processes show promise of being much less expensive than current technologies. The philosophy and economics behind the cold mill environmental improvement plan and the successes achieved so far will be reviewed.
