Rolling Mill

Rolling Mill refers to a comprehensive industrial facility that processes metal by passing it between pairs of rollers to reduce its thickness, achieve uniformity, and refine its mechanical properties.

In the context of tube and pipe manufacturing and galvanizing, the rolling mill plays a fundamental, upstream role:

1. Strip Production: The mill takes raw steel slabs and converts them into the precise width, thickness, and material grade required for forming tubes. This material is delivered to the tube mill as large coils of Hot-Rolled Coil (HRC) or Cold-Rolled Coil (CRC).
2. Tube Mill Integration: While a tube mill itself contains a smaller set of forming rolls (the form stand), the main rolling mill is the supplier of the raw material.

The quality, dimensional accuracy, and surface finish of the coil produced by the rolling mill directly impact the weld quality, dimensional precision, and subsequent adhesion success of the galvanized coating. Therefore, the efficiency and precision of the rolling mill dictate the quality of the final galvanized pipe product.
