Water Box
Cooling equipment at the point of production.
The BOYE Water Box applies cooling water to hot-rolled bar and wire rod as the product passes through the cooling section. The equipment brings the cooling nozzles and product passage together, with the arrangement selected to suit the mill layout, product range and cooling duty.
Bring water delivery and the product path together.
A Water Box is the physical cooling assembly. Its nozzles, installation position and water connections must work with the rolling conditions of the line.
Apply water along the cooling passage
Cooling nozzles deliver water to the moving product. The required cooling duty guides the nozzle arrangement and its position within the rolling process.
Prepare the cooling components before delivery
BOYE’s dedicated nozzles undergo water-flow calibration before delivery. Spray-angle verification, materials and heat treatment are part of the nozzle development process.
Match the assembly to the site
Review the pass line, nearby equipment, pipework and service space together. Clear installation interfaces help the mill team plan fitting, alignment and maintenance.
Build the cooling duty around the nozzle.
BOYE’s equipment documentation identifies three steps used to prepare its dedicated cooling nozzles.
Spray-angle simulation and verification
Review water application at the nozzle as part of the cooling-component design.
Water-flow calibration before delivery
Check the nozzle’s water delivery before it is put into service on the production line.
Wear-resistant materials and heat treatment
Prepare the nozzle for repeated service in the rolling-mill environment. Inspection and replacement intervals are set against actual operating conditions.
Specify the equipment and its interfaces together.
Send the operating conditions and a layout of the existing cooling section. These inputs define the equipment proposal and the work required to connect it to your line.
| Product and operation | Bar or wire rod, steel grades, product sizes and rolling speeds. |
|---|---|
| Cooling duty | Equipment position, incoming temperature, target temperature and the cooling stages used by the process. |
| Water supply | Available water pressure and flow, supply condition, connection points and drainage arrangement. |
| Mechanical interfaces | Pass-line centre height, available installation length, supporting structure and the entry and exit connections to adjacent equipment. |
| Service access | Inspection space, nozzle access, maintenance arrangements and the mill’s planned shutdown window. |
Connect the Water Box to the wider cooling solution.
The Water Box applies cooling water. A servo valve station regulates water flow and switching; temperature instruments and the control system provide the feedback used to adjust cooling.
