Hot rolling is a metalworking process where steel is heated above its recrystallization temperature (typically above 1,000°C) and then passed through rollers to achieve the desired shape. The material remains malleable, allowing it to be formed into various shapes, including bars, rods, plates, and coil

Advantages of Hot Rolling

1. Cost Efficiency

Since the metal is more malleable at high temperatures, it requires less force to shape, reducing equipment wear and operational costs.

2. Higher Production Rates

Hot rolling allows for continuous production of large

volumes of steel products, making it the preferred method for producing merchant bars, long products, and wire rods in bulk.

3. Enhanced Ductility and Formability

Because hot-rolled steel remains at high temperatures during processing, it is easier to shape into different forms. This makes it ideal for producing structural sections, beams, plates, and coils with high flexibility and adaptability.

4. Improved Metallurgical Properties

Hot rolling eliminates internal stresses and improves the overall grain structure of the steel. This results in better mechanical properties for structural applications, making it ideal for sections, wire rods, and long products.

5. Ideal for Large and Heavy Components Larger steel components, such as plates and coils, benefit from the hot rolling process as it allows for the production of thick and wide steel products without significant internal defects.

6. Easier to Weld and Machine

Hot-rolled steel is easier to weld and process due to its softer nature compared to cold-rolled steel.

This is particularly advantageous for applications in construction, shipbuilding, and manufacturing of large machinery.

7. Suitability for Structural Applications

Hot-rolled steel is commonly used in structural applications where precise surface finish and tight tolerances are not required. Products such as beams, angles, and channels are predominantly manufactured through hot rolling due to its efficiency and cost-effectiveness.

Applications of Hot-Rolled Steel

•   Merchant Bars & Long Products: Used in construction, infrastructure, and industrial applications where strength and flexibility are
required.

•   Plates & Coils: Essential for shipbuilding, heavy machinery, and automotive industries.

•   Wire Rods: Used in manufacturing reinforcement bars, fasteners, and welding wires.

•   Sections: Structural steel components for bridges, buildings, and industrial frameworks.

• Conclusion

• Hot rolling remains the preferred choice for large-

• scale industrial applications. Its cost efficiency, high production rates, enhanced formability, and superior metallurgical properties make it ideal for merchant

• bars, long products, plates, coils, wire rods, and structural sections.
