Scraper Bars — Bottom Ash Conveyor

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.

• 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.

Looking to reduce scraper wear or downtime in your ash handling systems? Contact us today to design your next-generation scraper bar solution—tailored to your exact wear profile and ash load conditions.

At Constromech our fabricated pans are engineered specifically for dry bottom ash handling systems, delivering outstanding durability and performance in thermal power plants that rely on round-link chain conveyors.

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.

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.

Built-in forged alloy steel connectors are heat-treated to ≈55 HRc, chemically and mechanically matched for seamless integration with your chain conveyors.

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.

• 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

With deep expertise in bottom ash systems, we engineer pans that exceed the rigorous specifications. Our deliverables include:

• Customized pan sizes, wall thicknesses and wear plate configurations
• One to One replacement with OEM fitment
• Heat-treated connectors compatible with your chain assemblies
• Full QC, material traceability, fabrication documentation, and onsite support
