Hot Rolled Steel Sheet In Coil

LUZHEN Hot Rolled Steel Sheet In Coil process transforms raw steel into finished products through a series of precise and high-temperature stages. It begins with continuously cast slabs, primarily made from iron ore and coal. These slabs are first reheated to approximately 1200°C in a furnace to achieve a uniform, plastic state for rolling. After descaling via high-pressure water to remove surface oxides, the slab undergoes initial thickness reduction in a roughing mill, becoming a transfer bar.

The core of LUZHEN Hot Rolled Steel Sheet In Coil process is the finishing mill, a series of tandem rolling stands that progressively reduce the bar to its final thin gauge-typically between 1.2 and 25 mm. As the steel exits the finishing mill at around 900°C, it is rapidly and uniformly cooled to a specific coiling temperature on a controlled run-out table; this cooling rate is critical for defining the final metallurgical properties. Finally, the continuous strip is coiled into a tight, robust hot-rolled coil, which is the primary product form.

LUZHEN Hot Rolled Steel Sheet In Coil serves as the direct feedstock for cold rolling mills or can be further processed into flat sheets via levelling and shearing lines. For other product types, such as plates, structural sections, or rails, the process diverges after roughing, using dedicated plate, beam, or rail mills to produce the final shapes in cut-to-length formats.

Hot Rolled Steel Sheet In Coil is the first crucial forming stage in steel production where the material transitions from a "metallurgical product" to an "industrial semi-finished or finished product." High-quality hot-rolled material serves as the essential base for producing premium cold-rolled products.
