Technical Field
[0001] The utility model belongs to the technical field of hot-rolled coils, and more specifically, particularly relates to a corrosion-resistant hot-rolled coil. Background Art
[0002] Hot rolled coil, also known as hot rolled coil, is made of slab (mainly continuous casting slab) as raw material, and is made into strip steel by rough rolling unit and finishing rolling unit after heating. The hot steel strip coming out of the last rolling mill of finishing rolling is cooled to the set temperature by laminar flow, and is rolled into steel strip coil by coiler. The cooled steel strip coil.
[0003] Before using the hot-rolled coil, it is necessary to flatten it and then cut it. During cutting, the staff is required to mark the cutting length on the hot-rolled coil, which increases the labor cost and is prone to errors, affecting product quality. The material of the hot-rolled coil is usually metal, which can easily cause wear on the cutting knife of the cutting machine during cutting, increasing maintenance costs. In addition, the surface of metal products exposed to the air for a long time is prone to corrosion, affecting the service life of the hot-rolled coil.
[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a corrosion-resistant hot-rolled coil is provided to achieve a more practical purpose. Utility Model Content
[0005] In order to solve the above technical problems, the utility model provides a corrosion-resistant hot-rolled coil, which is achieved by the following specific technical means:
[0006] A corrosion-resistant hot-rolled coil comprises a hot-rolled coil body, a plurality of auxiliary cutting lines are equidistantly arranged on one side of the hot-rolled coil body, U-shaped frames are symmetrically installed on both sides of the hot-rolled coil body, a first threaded hole is arranged on one side of the U-shaped frame, a limit plate is rotatably installed on one side of the U-shaped frame, a second threaded hole is penetrated by the limit plate at one end close to the first threaded hole, and a fastening bolt is threadedly connected to the inner surface of the second threaded hole.
[0007] Furthermore, one end of the fastening bolt is threadedly connected to the first threaded hole.
[0008] Furthermore, a corrosion-resistant layer is provided on the surface of the hot-rolled coil body.
[0009] Furthermore, a heat insulation layer is provided inside the hot-rolled coil body.
[0010] Furthermore, a sound-absorbing layer is provided inside the hot-rolled coil body.
[0011] Furthermore, reinforcing ribs are provided inside the hot-rolled coil body.
[0012] Compared with the prior art, the utility model has the following beneficial effects:
[0013] The corrosion-resistant hot-rolled coil in the utility model, through the coordinated use of the hot-rolled coil body and the auxiliary cutting line, is convenient for workers to quickly locate the length of the hot-rolled coil that needs to be cut, and reduces the friction and resistance of the cutting knife during cutting, thereby reducing labor costs and maintenance costs.
[0014] The corrosion-resistant hot-rolled coil in the utility model, through the coordinated use of the corrosion-resistant layer, the heat-insulating layer and the sound-absorbing layer, is convenient for slowing down the speed at which the surface of the hot-rolled coil is damaged due to corrosion. At the same time, when the hot-rolled coil is used as a building material or a factory consumable material, heat and noise are blocked and absorbed, thereby extending the service life of the hot-rolled coil and improving the practicality of the hot-rolled coil.

[0024] Example:
[0025] As attached Figure 1 To Attachment Figure 4 As shown:
[0026] The utility model provides a corrosion-resistant hot-rolled coil, comprising a hot-rolled coil body 1, a plurality of auxiliary cutting lines 2 are equidistantly arranged on one side of the hot-rolled coil body 1, U-shaped frames 3 are symmetrically installed on both sides of the hot-rolled coil body 1, a first threaded hole 4 is arranged on one side of the U-shaped frame, a limiting plate 5 is rotatably installed on one side of the U-shaped frame, a second threaded hole 6 is penetrated at one end of the limiting plate 5 close to the first threaded hole 4, and a fastening bolt 7 is threadedly connected to the inner thread of the second threaded hole 6.
[0027] Among them, one end of the fastening bolt 7 is threadedly connected to the first threaded hole 4, and the fastening bolt 7 is screwed into the first threaded hole 4 and the second threaded hole 6 in sequence, so that the limit plate 5 is fixed to one side of the U-shaped frame, thereby clamping and fixing the hot-rolled coil body 1 to prevent the hot-rolled coil body 1 from spreading due to shaking.
[0028] The surface of the hot-rolled coil body 1 is provided with a corrosion-resistant layer 8 to reduce the corrosion of the hot-rolled coil body 1 during long-term use.
[0029] The interior of the hot-rolled coil body 1 is provided with a heat insulation layer 9, and when the outside temperature is high, the heat insulation layer 9 can block the heat.
[0030] A sound-absorbing layer 10 is provided inside the hot-rolled coil body 1 to isolate external noise.
[0031] Among them, a reinforcing rib 11 is provided inside the hot-rolled coil body 1 to improve the rigidity of the hot-rolled coil.
[0032] The working principle of this embodiment is as follows: when the coil is placed, the fastening bolt 7 is located in the first threaded hole 4 and the second threaded hole 6, so that the limit plate 5 is fixed to one side of the U-shaped frame, so as to clamp and fix the hot-rolled coil body 1, and prevent the hot-rolled coil body 1 from spreading due to shaking. When the hot-rolled coil needs to be used, the fastening bolt 7 is unscrewed and the limit plate 5 is rotated so that the limit plate 5 no longer limits the hot-rolled coil. At this time, the U-shaped frame 3 can be removed, and the hot-rolled coil can be unfolded for subsequent processing. The setting of the auxiliary cutting line 2 can facilitate the staff to quickly locate the position where the hot-rolled coil body 1 needs to be cut, and reduce the wear on the cutting machine during cutting. In addition, the corrosion-resistant layer 8 on the surface of the hot-rolled coil body 1 can reduce the corrosion of the hot-rolled coil body 1 during long-term use. The heat insulation layer 9 inside the hot-rolled coil can block heat, the sound-absorbing layer 10 can absorb noise, and the reinforcing ribs 11 can improve the rigidity of the hot-rolled coil.
