Description of the case
Hoppers, chutes, several parts of a recycling line for slag (slag is the solid residue from the combustion of municipal /urban waste in incineration plants).
Previous material / thickness: S355/6mm
New material / thickness: Hardox® 450 / 6 mm
Lifetime increased (to be evaluated but minimum 3 or 4 times acc. to last inspection/controls).
Less maintenance on parts usually changed every month with the previous .
Increased productivity. Less production stops = 3 or 4 STOP DAYS are needed to replace those parts every one/two months. Less maintenance = less incident and accident risks (safety).
