Scrapper Bar
Engineered for Extreme Conditions. Fabricated for Long Life.
Product Construction
Structure: Scrapers are fabricated using heavy-duty structural channels, angles, or rectangular pipes, chosen for high mechanical load capacity and corrosion resistance asper their yield strength and higher fatigue points.
Scraping Surface:
- Cladded with welded-on wear-resistant hard plates, typically in the 440–500 BHN range, tailored to the ash abrasiveness and plant requirement.
- Hard-plating ensures maximum lifespan even under high-temperature and abrasive slurry environments.
End Connectors:
- Manufactured from forged alloy steel to match the hardness, tensile and fatigue properties of the paired round link chains.
- Heat-treated up to 55 HRc, chemically matched to prevent interface erosion and ensure mechanical integrity.
Key Advantages
| Feature | Benefit |
| Fabricated Modular Design | Easy field replacement and adaptable to various conveyor widths |
| Welded Hard Cladding (440–500 BHN) | Exceptional abrasion resistance in high-wear bottom ash environments |
| Forged & Heat-Treated Connectors (up to 55 HRc) | Matched mechanical performance with round link chains |
| Custom Lengths & Profiles | Precision-fitted to trough design and material characteristics |
| Compatibility | Works seamlessly with standard submerged and dry bottom ash conveyor systems |
Ideal for
- Submerged Chain Conveyors (SCC)
- Dry Bottom Ash Handling Systems
- Power Plants up to Ultra Supercritical Grade
Backed by decades of field-tested experience, our scraper bars are in active deployment across leading Indian and international thermal power plants.
Let’s Talk Performance
Fabricated Pans for Dry Ash Conveyors
Product Highlights
Heavy-Duty Fabrication
Crafted from structural channels, angles, or rectangular steel pipes for top-tier structural integrity.
Designed to withstand thermal shock from red-hot ash and large slag lumps.
Integrated Wear Protection
Welded-on hard plates rated 440–500 BHN across the pan bottom and sides.
Customizable hardness grades for specific plant operating conditions ensure minimal wear.
Round-Link Chain Compatibility
Built-in forged alloy steel connectors are heat-treated to ≈55 HRc, chemically and mechanically matched for seamless integration with your chain conveyors.
Modular & Service-Friendly
Pans are bolt-together modular units—fast and easy swap-out during maintenance, reducing downtime.
Smooth interiors reduce material hang-up and eliminate ash retention zones.
Key Benefits
| Feature | Benefit |
| Precision fabrication & weld quality | Enhanced structural strength; handles heavy ash loads and impacts |
| Wear-resistant hard cladding | Maintains long service life under abrasive conditions |
| Compatible connectors | Ensures secure fit with round-link chains, prevents fatigue |
| Service modularity | Enables rapid field assembly and maintenance |
| Adapted for dry conveyor cooling | Designed for dry ash in forced draft air-cooled environment |
Ideal Applications
- Dry bottom ash systems in thermal power plants
- Round-link chain conveyors using air-cooling
- Retrofit and new-build systems aiming to eliminate wet ash handling
