Conveyor Roller For Walking Beam Transfer Bed

Suitable for acceleration rollers, U‑groove rollers and various transfer rollers on steel rolling mills, they deliver outstanding wear‑resistance, anti‑erosion and high‑temperature stability. On‑site mill operation records confirm our laser‑cladded rollers achieve up to 800,000 tons of steel passing volume within 10 months, showing only minor surface wear with no spalling or cracking after long‑term continuous production.

Laser cladding applies high‑energy laser beam as heat source, feeding alloy powder synchronously into the molten pool. Powder material and roller substrate melt rapidly and solidify to build a firmly bonded protective overlay. Dilution rate is precisely controlled within 3%‑8% (below 5% for premium process), which retains the full functional performance of cladding alloy material.

WC (Tungsten Carbide) composite cladding option is available for extreme abrasive service scenarios.

✅ Robust Metallurgical Bonding

The cladding layer forms true metallurgical bonding with roller base metal, reaching substrate‑level bonding strength. Resists peeling, cracking and impact load, delivering far higher reliability than thermal‑sprayed coatings. Longer service life and superior load‑bearing & anti‑shock performance.

✅ Minimal Heat‑Affected Zone & Low Workpiece Distortion

Concentrated laser energy creates small molten pool with rapid cooling speed. Roller overall deformation is extremely limited; base metal microstructure remains nearly unaffected. Less post‑cladding machining required, well‑suited for large‑size precision transfer rollers.

✅ High Hardness & Superior Abrasion Resistance

Surface hardness ranges HRC45‑55. For WC‑reinforced cladding, service life reaches 2‑5 times of conventional hard‑facing weld overlay, 5‑10 times of ordinary heat‑treated rollers, and can exceed 10‑fold lifespan under severe particle abrasive wear conditions. Excellent anti‑scouring performance against sinter, coke, ore and hot steel particles.

✅ Good High‑Temperature & Corrosion Resistance

Nickel‑base alloy cladding systems (Ni625, Inconel625, Hastelloy etc.) support continuous working temperature from 500℃ to 800℃, resisting oxidation and medium corrosion under hot rolling environment.

✅ Localized Surface Strengthening & Remanufacturing Capacity

Only wear zones such as U‑groove, roller working surface are cladded. Saves expensive alloy consumables, cuts processing cycle and operational cost. Worn, corroded or dimension‑deviated used rollers can be fully repaired to original drawing dimension and performance. Compared with purchasing brand‑new rollers:

Cost reduced by 30%‑70%

Lead‑time shortened by over 50%

Multiple repeated repairs are achievable

✅ High Automation & Eco‑Friendly Manufacturing

Manufactured with robot‑driven multi‑axis CNC laser cladding equipment with automatic powder feeding and path planning. Stable, repeatable coating quality for batch orders. Less fume, spatter and lower energy consumption vs traditional manual hard‑facing welding, complying with green manufacturing standards.

Steel mill roller remanufacturing & new‑roller surface strengthening

Heavy‑load conveying under abrasive wear, hot particle scouring and medium‑high temperature conditions

Laser‑cladded conveyor rollers for walking‑beam transfer beds integrate surface strengthening and component remanufacturing. Featuring strong metallurgical bonding, low dilution rate, minor deformation, excellent wear‑resistant and high‑temperature performance, they effectively extend roller service cycles, reduce frequent equipment downtime and cut total ownership cost for steel plants.
