Product Description
Manufactured at our Jingjiang metallurgical equipment production facility, our Cooling Bed For Rolling Mill is a heavy-duty material-handling system engineered to receive red-hot rolled steel products-including plates, bars, sections, and billets-from the finishing mill and convey them along a controlled path for uniform atmospheric cooling and natural leveling. Leveraging 26 years of heavy fabrication experience and serving international steel producers such as Baowu, POSCO, and KINSTEEL, we construct each Cooling Bed For Rolling Mill in disc-roller or walking-beam configurations to prevent surface scratching, mechanical deformation, and residual internal stresses. Built with precision-machined drive shafts, rigid lifting-traversing linkages, and automated cycle controls, this rugged Cooling Bed For Rolling Mill maximizes usable cooling area while maintaining smooth product transfer, providing hot-rolling mills with a reliable, continuous-duty finishing floor asset.
Applications
Medium & Heavy Plate Mills: Delivering scratch-free air cooling and thermal straightening for rolled structural and pressure-vessel steel plates.
High-Speed Rebar & Bar Mills: Receiving high-speed rolled bars from dividing shears for uniform rack-cooling and rake straightening.
Section & Beam Rolling Lines: Handling structural channels, angles, and H-beams through stepped cooling cycles.
Billet & Bloom Continuous Casting Lines: Serving run-out tables to dissipate heat from cast billets prior to downstream bundling or charging.

Customization Capabilities
Disc-Roller Bed Tailoring: Multiple individually driven roller shafts fitted with alternating cast-steel disc wheels, providing scratch-free support where contact points change continuously during plate travel.
Walking-Beam Hydraulic Kinematics: Adjustable stroke cycles for lifting and stepping beams, allowing operators to change product spacing for different cooling speeds.
Integrated Entry/Exit Automation: Matching run-in roller tables, hydraulic side-shifting sweepers, plate centering stops, and run-out transfer chains engineered into the package.
Wear-Resistant Contact Surfaces: High-temperature alloy or surface-hardened contact plates to prevent galling on hot steel.
Turnkey Equipment Packages: Available as complete multi-section systems or modular drop-in replacements for brownfield mill modernizations with zero MOQ.
Quality Control
Manufacturing Accreditations: ISO 9001:2015, ISO 14001:2015, and ISO 3834-2 welding quality management.
QR Code Traceability: Every shaft, fabricated beam, hydraulic manifold, and drive bracket carries an individual QR code linked to certified material and inspection records.
Shop Trial Assembly & Alignment: 100% full-length pre-assembly and dry-cycling in our workshop to verify lifting kinematics, shaft runout, and gear-motor synchronization before shipment.
Third-Party Witness Inspections: Factory testing coordinated with BV, SGS, or client inspection engineers.
Heavy Ocean Packaging: Sturdy steel transport frames, greased machined surfaces, protective timber saddles, and weather-sealed shrink wraps.
FAQ
Q: What are the main benefits of a disc-roller cooling bed over a conventional sliding-rack bed for plate mills?
A: In a disc-roller cooling bed, the plate rests on rotating discs with no relative sliding motion. This eliminates bottom-surface gouging, ensures uniform air exposure on both sides, minimizes plate distortion, and allows high throughput.
Q: What is the typical lead time for a complete rolling mill cooling bed?
A: Custom-engineered cooling beds typically require 4 to 6 months from technical drawing approval to factory dispatch, depending on length and hydraulic scope.
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), backed by field-commissioning engineering support.
Q: What payment terms do you support?
A: Standard terms are 30% advance deposit, 40% intermediate fabrication milestone payment, and 30% balance prior to export shipment under EXW or FOB terms.
