The Manufacturing Process Behind Hot Rolled Steel

The Manufacturing Process

Slab Selection & Heating:

The journey of hot rolled steel begins with the selection of high-quality metal slabs, which are fed into a Reheating Furnace, where the slabs are heated in a furnace to extreme temperatures, often exceeding 2,200 degrees Fahrenheit (1,204 degrees Celsius), based on the type of steel grade being rolled.

Primary Descaling:

When the slabs exit the furnace, the slabs are covered with oxide layer which needs to be removed before rolling. Descaling involves high-pressure water jets (220 Bar) that clean the surface and prepares it for further processing.

Rolling:

Once the slab is descaled, it passes through a series of rollers. These rollers exert tremendous pressure, reducing the thickness of the steel slab and rolling to long steel strips.

Laminar Cooling:

Before the steel strip is rolled to coils, the steel strip is cooled by a laminal water stream in the hot rolling mill. This helps to stabilize the steel's microstructure, achieving the required properties.

Coiling:

The steel strip is then coiled for further processing or dispatched directly to our customers.
