Reciprocating Grate Spare Parts
We supply durable replacement parts for reciprocating (stepped) grate stokers, produced at the partner factory, designed to withstand the sliding contact and thermal cycling of reciprocating motion.
Available parts
- Moving grate bars — reciprocating grate bars that slide to push fuel forward
- Fixed grate bars — fixed grate bars that form the stepped grate surface
- Wear plates — replaceable wear surfaces at contact points
- Guide rails — guide components for reciprocating motion
- Hydraulic components — cylinder connections, pivot pins and bushings (for hydraulic drive systems)
Materials
- Cr25Ni20 (310S) — heat-resistant alloy for grate bars
- Cr26Ni12 — for zones with lower temperature requirements
- Wear plates with Stellite or equivalent hardfacing
Machining and inspection
- Precision casting and machining to ensure correct fit
- Heat-treated to obtain the required mechanical properties
- Dimensional inspection before shipment
- Competitive prices for both standard and custom parts
