The cooling system must remove heat at a controlled rate as the wire rod travels across the conveyor. The airflow requirement changes with steel grade, rod diameter, line speed and target metallurgical properties.
Air must be distributed across the conveyor width and through the active cooling zones. Fan quantity, spacing, plenum design, dampers and outlet geometry all affect uniformity.
The fan system should also support different production recipes. Independent zones, staged fan operation or variable-speed control can help match airflow to changing line conditions.
The fan must deliver the required cooling airflow after losses from inlet screens, ducts, plenums, dampers, headers, outlets and protective grilles are included.
A low-pressure axial fan may suit direct fan-bank cooling, while centralized duct systems or narrow outlets may require a centrifugal or higher-pressure fan direction.
For a new line, fan quantity, zone length, plenum arrangement and control method should be coordinated with the required cooling curve and production mix.
For an existing line, compare fan performance with plenum balance, outlet blockage, motor load, fan spacing and actual temperature distribution.
It is a controlled-air system that removes heat from hot wire rod after rolling. A fan bank or centralized air system distributes cooling air across the conveyor to influence cooling rate and product consistency.
Uneven airflow can create different cooling rates across the conveyor width or along the wire rod coil. Plenum design, fan spacing, dampers and outlet geometry all affect distribution.
Airflow depends on wire-rod diameter, steel grade, line speed, inlet temperature, target cooling rate, conveyor width and the number of active cooling zones.
Higher pressure may be required when air must pass through long ducts, headers, narrow nozzles, control dampers or high-resistance cooling modules.
Send fan and motor nameplates, airflow, pressure, speed, power, installation dimensions, cooling-zone layout and the current problem such as insufficient cooling, uneven temperature or high vibration.
The dedicated wire-rod air cooling axial fan is the primary product direction. GD30K2-12, 4-2×72, 9-19 and 9-26 may support auxiliary, centralized or higher-pressure project requirements after operating-point confirmation.
