Scrapper Bar

Engineered for Extreme Conditions. Fabricated for Long Life.

Constromech offers robust, custom-fabricated scraper bars designed for heavy-duty bottom ash conveyor systems in thermal power plants. Our scraper bars combine precisely engineered fabrication, advanced cladding, and metallurgy-aligned forging—ensuring superior wear resistance and seamless performance under the harshest ash handling conditions.

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.

Fabricated Pans for Dry Ash Conveyors

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.

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
