Hot rolling is the method used to manufacture Steel I-beams. The process begins by heating a large rectangular billet of steel until it becomes malleable and can be shaped into the desired I-beam profile. Subsequently, the billet is passed through a series of rolling mills that progressively shape it into the final I-beam shape.
To initiate the hot rolling process, the billet is heated in a furnace to a specific temperature, typically around 1200 to 1300 degrees Celsius. This elevated temperature increases the steel's ductility and makes it easier to form. Once the desired temperature is reached, the billet is fed into the first rolling mill.
The rolling mill comprises a set of rollers that gradually transform the heated billet into the I-beam profile. By applying pressure to the steel, the rollers elongate it and give it the desired shape. As the billet passes through each set of rollers, it becomes progressively thinner and longer, and the top and bottom flanges of the I-beam start to take form.
After the initial rolling mill, the partially formed I-beam undergoes further shaping in subsequent rolling mills. These mills continue to apply pressure and refine the shape of the I-beam until it reaches its final dimensions. The final step in the hot rolling process involves cooling the newly formed I-beam to room temperature, which can be achieved through air cooling or water quenching.
Once the I-beams have been cooled, they are cut to the desired length and undergo any necessary additional processing, such as surface treatments or galvanization. At this point, they are ready for use in various construction projects, where their strength and structural integrity make them an ideal choice for supporting heavy loads and spanning long distances.

The first step in the hot rolling process is heating the billet in a furnace to a specific temperature, typically around 1200 to 1300 degrees Celsius. This high temperature makes the steel more ductile and allows it to be easily formed. Once the billet reaches the desired temperature, it is fed into the first rolling mill.
The rolling mill consists of a series of rollers that gradually shape the heated billet into the I-beam profile. The rollers apply pressure to the steel, causing it to elongate and take on the desired shape. As the billet passes through each set of rollers, it becomes progressively thinner and longer, with the top and bottom flanges of the I-beam taking shape.
After passing through the initial rolling mill, the partially formed I-beam undergoes further shaping in subsequent rolling mills.

Steel I-beams are manufactured through a process called hot rolling, where molten steel is transformed into a long, solid beam shape. The steel is first melted in a furnace and then poured into a continuous casting machine to form a billet. The billet is then heated and passed through a series of rolling mills, which apply pressure to shape it into the desired I-beam profile. Finally, the beam is cut to the required length, cooled, and prepared for delivery or further processing.
