A Hot Strip Mill Laminar Cooling Spray Header distributes cooling water to nozzle arrays on the runout table, enabling controlled cooling after finishing stands. Cooling uniformity and repeatability are critical to achieving stable mechanical properties, shape control, and the target coiling temperature window. In practice, the spray header is a key hardware element that supports predictable cooling performance across campaigns.

In mill environments, spray headers face thermal radiation, water hammer, scale, and frequent start–stop cycles. The most important engineering points include structural rigidity, fatigue resistance at welded joints, sealing stability, and consistency of nozzle interfaces. Where internal manifold design is involved, pressure balancing and flow uniformity also influence cooling effectiveness and maintenance workload.

Runwo manufactures spray headers with an end-to-end fabrication route, including forming, welding, machining of critical interfaces, surface treatment, and inspection documentation. For replacement or new build projects, providing strip width, nozzle layout, design flow/pressure, connection standards, and installation constraints helps define a practical manufacturing plan and an acceptance checklist that reflects mill realities.
