Processing process of hot rolled hollow section:
1. Choose high-quality materials without any defects.
2. Cut the steel to the required length and heat it to a specific temperature according to the grade of the steel.
3. The heated steel is rolled into a tube shape using a series of rollers. During this process, the steel is subjected to high pressure, which helps shape it into the desired shape.
4. Pass through a series of rollers to remove any burrs or unevenness.
5. Use air or water to cool hollow profiles. This process helps stabilize the steel and prevent any warping or twisting.
6. Use plasma cutting, laser cutting and sawing to cut the hollow profile
Advantages:
1. The manufacturing process of hot-rolled hollow profiles is cheaper and requires less material
2. Hot-rolled hollow profiles have higher yield strength and tensile strength, are stronger and more durable, and are often used in heavy-duty applications
3. Hot-rolled hollow profiles are easy to manufacture and can be cut, welded and shaped to meet specific requirements.
4. Stable quality: The manufacturing process of hot-rolled hollow profiles makes the product quality stable. This ensures that every piece of material has the same strength and durability.
Application:
1. Hot-rolled hollow profiles are most commonly used in building construction. There are also load-bearing components. They offer superior strength and stability, ensuring the safety of the building and its occupants.
2. Hot-rolled hollow profiles are also used in the construction of bridges, tunnels, and highways to provide structural support and improve the overall safety of these infrastructure projects.
3. Hot-rolled hollow profiles are used in the construction of industrial machines and equipment, as well as in the production of consumer goods such as furniture and appliances. Can withstand heavy loads and harsh environments
4. In addition, hot-rolled EN10025 hollow profiles are widely used in the oil and gas industry due to their corrosion-resistant properties.
