We are a professional supplier of hot rolling machines. As the core equipment for metal processing, the application and characteristics of hot rolling machines can be summarized as follows:
1. Main application fields
Construction industry: used for producing load-bearing components such as steel beams and columns, meeting high-strength requirements.
Automobile manufacturing: processing body structure parts and chassis components, taking advantage of its good formability.
Mechanical manufacturing: manufacturing equipment bases and transmission shafts, relying on its high strength and plasticity.
Transportation and energy: such as the use of hot-rolled bridge steel plates in the North Corridor High-Speed Railway project, demonstrating its engineering applicability.
2. Core characteristics
Process advantages
High-temperature rolling (above the recrystallization temperature), reducing deformation resistance, low energy consumption and good plasticity.
Large ingot, large reduction production, high efficiency, suitable for large-scale manufacturing.
Material properties
Improving the microstructure of cast materials through hot rolling, significantly enhancing the material's ductility.
Higher product strength, but rougher surface, suitable for subsequent processing.
Equipment and technology
Modern hot rolling machines tend to be automated and precise, such as four-roll and compound rolling machines.
Intelligent technology (such as the online grinding of the guide rolls in Taigang) improves quality and safety.
3. Comparison with cold rolling
Temperature: hot rolling is carried out at high temperatures, while cold rolling is at room temperature.
Performance: hot rolling has good toughness, while cold rolling has a finer surface but poorer ductility.
Thickness: the thickness range of hot-rolled coils (1.2~25.4mm) is greater than that of cold rolled (0.3~3.5mm).
Through continuous technological upgrades, hot rolling machines have further expanded their applications in heavy machinery, ships, and other fields.
