Abstract
Description
Technical Field
[0001] This invention relates to the field of steel profile manufacturing technology, and more specifically to a hot-rolled corrugated web H-beam production equipment and manufacturing method thereof. Background Technology
[0002] H-beams are a type of profile steel. They have advantages such as strong bending resistance, simple construction, cost savings, and light structural weight, and have been widely used.
[0003] H-beams consist of an upper flange, a lower flange, and a web between the upper and lower flanges. Steel structures primarily composed of H-beams are scientifically sound, possess good plasticity and flexibility, and exhibit high structural stability. They are suitable for building structures subjected to high vibration and impact loads, and have strong resistance to natural disasters, making them particularly suitable for building structures in earthquake-prone areas.
[0004] Currently, the height and width of H-beams are rationally allocated according to different uses. Among them, the web is usually a flat web with a relatively thick thickness, resulting in low material utilization. In some large steel structures, it is usually necessary to increase the size of the H-beam to ensure its load-bearing capacity, which increases material consumption and is not conducive to energy conservation, environmental protection, cost reduction and efficiency improvement.
[0005] Therefore, how to provide equipment capable of producing H-beams with corrugated webs, so that smaller H-beams can replace larger ones to bear the load, is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention
[0006] In view of this, the present invention provides a hot-rolled corrugated web H-beam production equipment and manufacturing method thereof. Using this equipment, the flat web of the H-beam can be manufactured into a corrugated web, which effectively improves its load-bearing capacity and self-weight, thereby reducing steel consumption, energy consumption and carbon dioxide emissions.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A production equipment for hot-rolled corrugated web H-beams includes rolls and support rolls;
[0009] The rolls include an upper roll and a lower roll; both the upper roll and the lower roll are rotatably connected to the universal rolling mill and are symmetrically positioned on both sides of the web of the H-beam; the outer circumferential surfaces of the upper roll and the lower roll are wavy surfaces, and the crests of the upper roll correspond to the troughs of the lower roll.
[0010] The number of support rollers is two and they are slidably connected to the universal rolling mill; the two support rollers are symmetrical on both sides of the flange of the H-beam and their ends can slide against the flange of the H-beam.
[0011] The beneficial effects of the technical solution of this invention are that the web of H-beams is rolled into a wavy web by the upper and lower wavy rollers. The wavy web can effectively improve the load-bearing capacity of H-beams. In some large steel structures, H-beams with wavy webs of lower grade can be used to replace ordinary H-beams of higher grade without reducing their load-bearing capacity. This can reduce material waste and carbon dioxide emissions, making construction more energy-efficient and environmentally friendly.
[0012] Preferably, both the upper roll and the lower roll include a drive roll and a work roll; the drive roll is rotatably connected to the universal rolling mill; the work roll is integrally formed on the circumferential surface of the drive roll, and the outer circumferential surface of the work roll is the wavy surface. The drive roll and the work roll are arranged concentrically, with the work roll located on the circumferential surface of the drive roll. The drive roll drives the work roll to rotate, thereby realizing the rolling of the wavy web.
[0013] Preferably, the width of the working roller is smaller than the width of the drive roller.
[0014] Preferably, the work roll is detachably connected to the drive roll, and the width of the work roll is adapted to the web height of the H-beam. Different types of work rolls can be used to meet the rolling requirements for corrugated webs of different types of H-beams.
[0015] This invention also provides a method for manufacturing hot-rolled corrugated web H-beams, using one of the hot-rolled corrugated web H-beam production equipment described above, comprising the following steps:
[0016] S1, H-beam steel raw material heating;
[0017] S2. Raw material pressing: The web of the heated H-beam is rolled into a wavy shape using upper and lower rollers.
[0018] S3. Cool the rolled H-beams to reduce their temperature;
[0019] S4. Straighten the cooled H-beams using a straightening machine.
[0020] Preferably, in step S1, the temperature at which the raw material is heated is 1000–1250°C.
[0021] Preferably, in step S2, the total elongation coefficient is calculated based on the cross-sectional area of the H-beam raw material and the rolled H-beam, and the number of rolling passes is determined according to the elongation capacity of an average elongation coefficient of 1.2 to 1.45.
[0022] Preferably, in step S3, the temperature is cooled to ≤100°C.
[0023] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a hot-rolled corrugated web H-beam production equipment and its manufacturing method. Using this equipment, the flat web of the H-beam can be manufactured into a corrugated web, which effectively improves its load-bearing capacity and reduces carbon dioxide emissions, while reducing the weight of the H-beam, reducing energy waste and carbon dioxide emissions.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0030] Example 1
[0031] like Figure 1 and 2 As shown, a hot-rolled corrugated web H-beam production equipment according to an embodiment of the present invention can transform the flat web of the H-beam into a corrugated web by rolling it with upper and lower rolls. The equipment includes roll 1 and support roll 2. Roll 1 includes upper roll 11 and lower roll 12. Both upper roll 11 and lower roll 12 are rotatably connected to a universal rolling mill and are symmetrically positioned on both sides of the web of the H-beam 3. The outer circumferential surfaces of upper roll 11 and lower roll 12 are corrugated, and the crests of upper roll 11 correspond to the troughs of lower roll 12. There are two support rolls 2, which are slidably connected to the universal rolling mill. The two support rolls 2 are symmetrically positioned on both sides of the flange of the H-beam 3, and their ends can slide against the flange of the H-beam 3.
[0032] H-beams are placed on the conveyor rolls of a universal rolling mill and supported by support rolls. The upper and lower rolls are symmetrically arranged on both sides of the web of the H-beam, with the crests and troughs on them facing each other. By rolling the web of the H-beam with the upper and lower rolls, its flat web can be transformed into a wavy web.
[0033] To further optimize the above technical solution, both the upper roll 11 and the lower roll 12 include an active roll 13 and a work roll 14; the active roll 13 is rotatably connected to the universal rolling mill; the work roll 14 is integrally formed on the circumferential surface of the active roll 13, and the outer circumferential surface of the work roll 14 is a wavy surface.
[0034] The drive roll provides the force required for rolling to the work roll. The corrugated structure on the work roll can be rolled by rolling along the web, transforming the planar web into a corrugated shape.
[0035] To further optimize the above technical solution and meet the rolling requirements of different types of H-beams, the work roll 14 is detachably connected to the drive roll 13, and the width of the work roll 14 is adapted to the web height of the H-beam 3.
[0036] To further optimize the above technical solution, the width of the working roller 14 is smaller than the width of the drive roller 13.
[0037] By rolling the web of H-beams into a corrugated shape, the weight of the H-beams can be reduced while increasing their load-bearing capacity. For the same type of steel structure, smaller corrugated H-beams can be used instead of larger ordinary H-beams, reducing the structural weight while maintaining load-bearing capacity. Since one ton of steel produces approximately two tons of carbon dioxide, corrugated web H-beams can reduce weight by about 40%, effectively reducing carbon dioxide emissions and achieving energy conservation and environmental protection.
[0038] Example 2
[0039] This invention discloses a method for manufacturing hot-rolled corrugated web H-beams, using a hot-rolled corrugated web H-beam production equipment as described in Example 1, comprising the following steps:
[0040] S1 and H-beam steel 3 raw material heating;
[0041] Use a continuous or walking beam furnace to heat the raw materials to 1000℃~1250℃, and control the furnace temperature and time to prevent overheating or burning.
[0042] S2. Raw material pressing: The heated web of H-beam 3 is rolled into a wavy shape by the upper roller 11 and the lower roller 12.
[0043] Using a universal rolling mill, on a continuous or semi-continuous rolling production line, the total elongation coefficient is calculated based on the cross-sectional area of the H-beam raw material and the rolled H-beam. The number of rolling passes is determined according to the elongation capacity of an average elongation coefficient of 1.2 to 1.45, and the rolling of the raw material into a corrugated web is completed.
[0044] It is important to note that during the rolling process, the troughs of the upper roll must correspond to the crests of the lower roll, that is, the upper and lower rolls must be aligned so that the flat web can be transformed into a wavy web.
[0045] S3. Cool the rolled H-beam 3 to reduce its temperature;
[0046] The rolled H-beams are cooled to ≤100℃ using a walking or walking chain hybrid cooling bed.
[0047] S4. Straighten the cooled H-beam 3 using a straightening machine.
[0048] Use either a cantilever or gantry straightening machine. The size of the straightening machine should be selected according to the size of the rolled H-beam. Straighten the rolled H-beam at ≤100℃ in one piece. After straightening, perform cutting, quality inspection, load-bearing capacity testing, and other tests.
