High Quality Hot-rolled Steel Coil Black Steel Coil S235 S355 SS400 Carbon Steel Coil

Short Description:

Hot rolled steel coil refers to the pressing of billets into the desired thickness of steel at high temperatures. In hot rolling, steel is rolled after being heated to a plastic state, and the surface may be oxidized and rough. Hot rolled coils usually have large dimensional tolerances and low strength and hardness, and are suitable for construction structures, mechanical components in manufacturing, pipes and containers.

Process of production

Processing Billets: Solidified billets or blooms undergo inspection, surface imperfections are removed, and they are heated to 1100–1250°C for plastic working.

Roughing: Hot billets are rolled in the roughing mill (3–7passes), which reduces the thickness from 150–300 mm to 20–50 mm and also modifies the width the form intermediate billets.

Finishing: Following descaling, the semifinished billet is rolled in the finishing mill (5–7 passes) to the final thickness (1.2–25.4 mm), and the speed and temperature of the rolling are controlled to obtain a desired microstructure/grain and mechanical properties.

Coiling: After being air quenched (laminar cooling) at a high cooling rate (500–700°C), the hot-rolled strip is coiled.

Inspection & Processing: The finished coils are inspected for size, mechanical properties and surface quality and then baled, tagged and either stored or shipped out.
