HROP (HR) COIL

HROP COIL (OIL & PICKLED)

We are manufacturing oil & pickled coils (HROP Coils) varies from thickness 1.2mm to 6mm. Coil maximum width 1500mm. The job work facility also available.

Products Making

  • Reheating: It involves heating to above recrystallization temperature. The non-uniform initial cast grain structure of metal consists of large dendritic grains.
  • Roughing & Finishing: The reduction is given up to approximately the required coil thickness from the initial slab/bloom thickness using roughing and finishing mill.
  • Laminar cooling: In some grades, rapid cooling of hot rolled coils is done using water in order to bring down the temperature below 500°C
  • Coiling: It is done in order to make the hot rolled sheet convenient for further processing and transportation.

Product features

Hot-rolled coils are often used in applications where dimensional tolerances are not very critical, such as railroads and construction materials.

HR Black: The hot rolled coils develop a brownish-black oxide layer on the surface after processing, hence referred to as “HR Black coils.”

HRAP: If a better surface finish is required, then oxide scaling can be removed by shot blasting (mechanically) and pickling (chemically) in order to obtain a No. 1 finish as per ASTM.

HRAP coils have a cleaner surface and have improved mechanical properties for downstream processing.
