hot-rollingHSection steel is a type of steel with a cross-sectional shape of“H”Shaped steel，Due to its high efficiency、Economic performance characteristics，Widely used in architecture、bridge、Fields such as mechanical manufacturing。It is produced through hot rolling process，The high-temperature steel billet is about to be rolled into the required shape by a rolling millHCross-sectional shape。
Production process
hot-rollingHThe production process of section steel mainly includes the following steps：
Heating of steel billets：Heat the steel billet to1200℃about，Make it have good plasticity。
roughing：Through multiple passes of rolling，Roll the steel billet into a shape close to the finished product。
finish rolling：Further rolling，Ensure dimensional accuracy and surface quality。
cooling：After rollingHSteel sections are cooled naturally or through controlled cooling，To obtain the required mechanical properties。
Straightening and inspection：After coolingHStraightening treatment of steel sections，Ensure its straightness，And conduct size and quality inspections。
Performance characteristics
hot-rollingHSteel sections have the following performance characteristics：
high strength：Capable of withstanding large loads，Suitable for building structures and bridges, etc。
Good weldability：Suitable for various welding processes，Convenient for on-site construction。
High dimensional accuracy：Strictly control the size during the production process，Ensure installation accuracy。
economic：Compared to other types of steel，HThe material utilization rate of section steel is high，Low cost。
application area
hot-rollingHSteel sections are widely used in the following fields：
building structure：Beams used for high-rise buildings、Column and other load-bearing structures。
bridge engineering：Main beams used for bridges、Supporting structures, etc。
Machinery manufacturing：Frame and support components used for manufacturing heavy machinery。
Industrial plant：Steel frame structure for factory buildings，Improve space utilization efficiency。
advantage
Compared to traditional I-beams，hot-rollingHSteel sections have a larger cross-sectional modulus and stronger bending resistance，At the same time, it is lighter in weight，Can effectively reduce the self weight of the structure，Improve the stability and safety of the structure。in addition，Its wing edge is wide、Design of thin web plate，Make it withstand the same load，Has better torsional resistance performance。
in short，hot-rollingHSteel sections are known for their excellent performance and wide range of applications，Plays an important role in modern industry and construction fields，To achieve efficiency、economy、Important materials for environmentally friendly building structures。
