Description of the case
The grates are used for aluminium cans recycling.
Originally the grates were cut / fabricated from astralloy V plate. At that time the grates were not hardfaced and overlayed with tungsten carbide. The grates have been redesigned to be cut from
Hardox® 450 steel plate and hardfaced with complex carbide overlay.
Grates Original Design ‐Astralloy V Plate / No Overlay = 3,000,000 Lbs/ 1.360.777 kg recycled aluminum before failure
Grate redesign ‐Hardox® 450 plate / complex carbide overlay = 70,000,000 Lbs/ 31.751.465 kg recycled aluminum before failure
Key success factors
Improved service life
