Product Description
Manufactured within our heavy metallurgical equipment workshop in Jingjiang, our Motorized Roller Conveyor is a heavy-duty industrial roller table system engineered for the longitudinal transportation of hot and cold steel products-such as slabs, billets, plates, bars, and rolled sections-across rolling mills and finishing processing lines. Drawing upon 26 years of specialized manufacturing experience and serving global metallurgical leaders like Baowu, Shagang, and POSCO, we construct each Motorized Roller Conveyor with forged or centrifugally cast rollers, heavy cast-steel bearing chocks, and automated lubrication manifolds designed to withstand severe thermal radiation, mechanical impact, and continuous scale abrasion. Representing up to 40% to 60% of total mill equipment tonnage, this durable Motorized Roller Conveyor operates as an indispensable backbone for hot breakdown and cold finishing lines, maintaining reliable, continuous-duty transfer that keeps rolling cycles on schedule.
Applications
Hot Breakdown & Roughing Mill Lines: Transporting red-hot ingots and heavy slabs to and from breakdown stands and reversing roughers.
Finishing Mill Run-In & Run-Out Tables: Receiving high-speed rolled plates and bars directly from mill stands and delivering them to flying shears and cooling beds.
Reheating Furnace Charge & Discharge Tables: Handling heavy billets and slabs entering and exiting continuous reheating furnaces.
Plate & Pipe Finishing Yards: Conveying cooled plates, structural beams, and seamless pipes through levelers, inspection stations, and marking bays.

Customization Capabilities
Hardfacing & Cladding Tailoring: Surface cladding formulations tailored to product temperature and scale wear, with dynamic balancing (ISO 1940 G6.3) for high-speed runs.
Specialized Roller Geometries: Cylindrical rollers, tapered centering rollers, or V-grooved rollers configured for billets, pipes, and rounds.
Internal Water-Cooling Channels: Forged hollow rollers with rotary joints for internal water circulation, designed for high-temperature furnace discharge areas.
Modular Frame Construction: Heavy welded steel box-frame tables with integrated scale-collection troughs and walkways, pre-aligned for fast site installation.
Zero MOQ Restriction: Custom fabrication of replacement rollers or complete turnkey roller table lines with zero minimum order quantity.
Quality Control
System Accreditations: ISO 9001:2015, ISO 14001:2015, and ISO 3834-2 welding quality management.
QR Code Traceability: Every forged roller body, shaft journal, bearing chock, and sub-assembly carries an individual QR code linked to certified test records.
Non-Destructive Testing: 100% Ultrasonic Testing (UT) on raw forgings, Magnetic Particle Testing (MT) on welded overlays, and runout inspections across all roller surfaces.
Dynamic Balancing & Run-In Testing: High-speed rollers undergo dynamic balancing tests and shop rotation trials to verify bearing operating temperatures and vibration signatures.
Heavy Ocean Packaging: Protective rust-preventive grease, machined journal wrap, heavy timber skids, and weatherproof vacuum-sealed covers.
FAQ
Q: How do you address thermal fatigue and wear on roller tables exposed to hot slabs?
A: We utilize multi-layer submerged-arc hardfacing with high-chromium, high-nickel wear-resistant alloy wires over a 42CrMo forged core. The surface is stress-relieved and finish-machined to resist heat cracking and scale wear.
Q: What is the typical lead time for a complete roller conveyor table section?
A: Complete table sections typically require 3 to 4 months from drawing sign-off to delivery. Standard replacement rollers can be supplied within 2 to 3 months.
Q: What warranty do you provide?
A: We provide an 18-month warranty from site arrival or 12 months from commercial operation (whichever occurs first).
Q: What payment terms do you accept?
A: Standard commercial terms are 30% advance deposit, 40% manufacturing milestone payment, and 30% balance prior to export shipment, payable in USD, EUR, or RMB.
