Conveyor Roller For Bar Rolling Mill Roller Table

The rollers cover multiple working positions of bar mill roller tables, including acceleration rollers, guide rollers, U-groove rollers, clamping rollers, inclined rollers, air-cooled rollers and cold bed entry rollers. They maintain stable roundness and surface quality under long-cycle hot rolling conditions, effectively preventing surface scratching, indentation and wear on finished bars.

Using a high-energy laser beam as the heat source, alloy powder is synchronously fed into the molten pool. The powder and roller substrate melt and solidify rapidly to form an overlay with low dilution rate, precisely controlled at 3%‑8% (≤5% for premium grade). The base material's original performance is well preserved, and the cladding layer delivers consistent designed alloy properties. WC carbide composite cladding is available for extremely harsh high-abrasion working conditions.

✅ Strong Metallurgical Bonding

The cladding layer forms metallurgical combination with the roller base, avoiding peeling, spalling and cracking under frequent impact from hot steel bars. It has far better shock resistance than conventional thermal spray coatings, greatly reducing unexpected downtime.

✅ Low Thermal Deformation & Less Post‑Machining

Concentrated laser heat input creates a narrow heat-affected zone and fast cooling. Roller deformation is kept minimal, and the base matrix structure remains stable. It is suitable for precision rollers with strict dimensional and runout requirements in bar rolling lines.

✅ High Hardness & Outstanding Wear Resistance

Surface hardness reaches HRC45‑55. With WC-reinforced cladding, service life is 2–5 times that of conventional surfacing welding rollers and 5–10 times that of ordinary heat-treated rollers. It resists continuous erosion from iron oxide scale, abrasive particles and hot billets, keeping the roller profile stable for a long time to guarantee bar surface quality.

✅ Excellent High-Temperature Oxidation Resistance

Nickel-based alloy cladding options such as Ni625 can work continuously at 500℃–800℃, resisting high-temperature oxidation and thermal fatigue under the alternating hot and cold environment of bar rolling production.

✅ Local Strengthening & Roller Remanufacturing

Cladding is applied only on the wear areas like U-grooves and working surfaces, saving high-cost alloy materials and shortening production cycles. Worn, dimensionally out-of-tolerance old rollers can be repaired back to original drawing specifications.

Repair cost: 30%–70% lower than new rollers

Delivery time: cut by more than 50%

Supports repeated reconditioning

✅ Stable Automated Production

Manufactured by multi-axis robotic laser cladding systems with automatic powder feeding and programmable path planning. Coating quality is consistent for bulk orders. Compared with traditional manual surfacing, it generates less smoke and spatter and meets green manufacturing requirements.
