S235jr S355jr SAE1006 Q235b ASTM A36 ST37 Iron Hot Rolled Carbon Steel Coil Manufacturer-1

Hot-rolled coil is a kind of metal coil produced through hot-rolling process, usually using steel, aluminum or other metals as raw materials. Hot-rolling process refers to pressing and rolling the metal billet into the required thickness of sheet or coil under high temperature by rolling mill. Hot-rolled coils are widely used in fields such as construction, automobiles, mechanical manufacturing, energy, etc., because of their high strength, low cost and good processing performance, they are highly favored.

    The production process of hot-rolled coil:


    Heating: Heat the metal billet above the recrystallization       temperature (typically ranging from 1100°C to 1300°C).
    Rolling: Roll the billet through the roughing and finishing rolling mills to achieve the desired thickness.
    Cooling: Cool the rolled sheet through cooling equipment Coiling: Coil the sheet into coils for convenient transportation and storage.
