Description

Technical Field

[0001] This utility model belongs to the technical field of steel processing equipment, specifically relating to a curling insulation cover device. Background Technology

[0002] In modern steelmaking continuous casting production lines, after high-temperature steel billets are pulled out of the continuous casting machine, they are usually cut into fixed lengths by a flame cutting machine that moves synchronously with the billets. Subsequently, the fixed-length steel billets are either transported to a cooling bed for cooling or directly hot-sent to the rolling mill for rolling (i.e., hot charging or hot delivery process).

[0003] To improve energy efficiency and reduce the temperature drop of steel billets during transport, hot conveying processes are widely adopted. However, at the flame cutting station, because the cutting machine needs to move a certain distance along the direction of the steel billet's movement to complete the cutting operation, this dynamic working area is usually open, making it impossible to install a fixed insulation cover. This results in the high-temperature steel billet being directly exposed to the surrounding environment in this critical section, leading to significant heat loss due to radiation and convection. This temperature drop not only significantly increases the reheating energy consumption of subsequent rolling processes but may also affect the temperature uniformity of the steel billet, adversely impacting product quality.

[0004] Therefore, how to provide continuous and effective heat preservation for the steel billet in this dynamic cutting area and reduce heat loss is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0005] Purpose of the invention: The purpose of this utility model is to provide a curling heat insulation cover device to solve the technical problem in the prior art that the cutting area of ​​continuously cast steel billets cannot be effectively insulated, resulting in serious heat loss.

[0006] Technical solution: The curled heat insulation cover device of this utility model includes: a horizontal track; a heat insulation cover chain composed of several interconnected heat insulation cover units, the heat insulation cover chain being disposed on the horizontal track; a connecting shaft for connecting adjacent heat insulation cover units; a toothed cylinder, the toothed cylinder engaging with the connecting shaft through tooth grooves on its outer wall; a toothed cylinder transmission mechanism connected to the toothed cylinder for driving the toothed cylinder to rotate; and an arc-shaped track for guiding the movement of the heat insulation cover units to ensure that the connecting shaft engages with the tooth grooves of the toothed cylinder. When the gear cylinder rotates, it drives the heat preservation cover unit to move along the horizontal track and the arc track. During the movement, it rolls up or unfolds to cover or expose the continuously cast steel billet.

[0007] To further improve the above technical solution, the insulation cover chain includes a trolley insulation cover as the head unit and at least one intermediate insulation cover.

[0008] Furthermore, the trolley insulation cover includes end beams and a cover body. The two ends of the cover body are fixedly connected to the two end beams. A motor and wheels are installed on the end beams. The motor drives the wheels to move the trolley insulation cover along the horizontal track.

[0009] Furthermore, the intermediate heat insulation cover includes two wheels and a cover body. The two ends of the cover body are fixedly connected to two wheels, and the wheels move on the horizontal track or the arc track.

[0010] Furthermore, the first and second cover bodies are hollow structures, and their interiors are filled with thermal insulation material.

[0011] Furthermore, the connecting shaft includes a shaft and roller sleeves fitted at both ends of the shaft. The roller sleeves mesh with the tooth grooves of the gear cylinder to realize the rolling up or unfolding of the intermediate heat insulation cover.

[0012] Furthermore, the gear cylinder includes a cylinder body and a gear ring, with the gear grooves provided on the outer rings of both sides of the cylinder body, and the gear ring meshing with the gear of the gear cylinder transmission mechanism.

[0013] Furthermore, the gear cylinder and the gear cylinder transmission mechanism are fixed by a bracket, and the gear cylinder is fixed on the bracket by a bearing seat.

[0014] Beneficial effects: Compared with the prior art, the advantages of this utility model are as follows: This device can move synchronously with the flame cutting machine to achieve dynamic and continuous coverage and insulation of the steel billet cutting area, effectively reducing the heat loss of the steel billet and increasing the hot delivery temperature; by reducing temperature drop, the reheating energy consumption of subsequent processes is significantly reduced, bringing considerable economic benefits to enterprises; the rigid drive method of toothed cylinder and connecting shaft meshing, combined with track guidance, ensures the smooth operation and reliability of the device during the rolling and unfolding process; the insulation cover chain is composed of modular insulation cover units, and the number of units can be flexibly increased or decreased according to the length of coverage required on site, making it highly adaptable.

[0023] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings, but the protection scope of this utility model is not limited to the described embodiments.

[0024] Example 1: As Figure 1 and Figure 2 As shown, this utility model provides a coiled heat insulation cover device, including a horizontal track 1, a heat insulation cover chain, a connecting shaft 4, a gear cylinder 5, a gear cylinder transmission mechanism 6, a bracket 7, and an arc-shaped track 8.

[0025] The horizontal track 7 and the curved track 8 are typically fixedly installed on a concrete foundation next to the production line, together forming the running path of the insulation cover chain. The horizontal track 7 is used to support the insulation cover chain to move a long distance in a straight line above the steel billet, while the curved track 8 connects one end of the horizontal track to the toothed cylinder, playing a guiding role so that the insulation cover unit can smoothly transition from horizontal movement to vertical winding movement. The insulation cover chain is the main component that achieves the insulation function. It consists of several interconnected insulation cover units and is used to cover the high-temperature steel billets on the continuous casting production line. In this embodiment, as shown... Figures 2 to 5 As shown, the insulation cover unit is specifically divided into a trolley insulation cover 2, which serves as the head unit, and several intermediate insulation covers 3. The trolley insulation cover 2 includes an end beam 9 and a cover body 10. A motor 11 and wheels 12 are mounted on the end beam 9. The motor 11 can independently drive the wheels 12, enabling the trolley insulation cover 2 to move actively on the horizontal track 1, providing auxiliary traction or maintaining tension for the entire insulation cover chain when it is deployed. The intermediate insulation covers 3 include a cover body 14 and wheels 13. Both wheels 12 and 13 can roll on the horizontal track 1 and the curved track 8.

[0026] To achieve the insulation effect, both the cover body 10 and the cover body 2 14 are hollow structures, and their interiors can be filled with high-efficiency thermal insulation materials, such as ceramic fiber cotton and aerogel felt, to maximize the prevention of heat loss to the surrounding environment.

[0027] The trolley insulation cover 2 is connected to the first intermediate insulation cover 3 and adjacent intermediate insulation covers 3 via a connecting shaft 4. For example... Figure 6 As shown, the connecting shaft 4 specifically includes a central shaft 15 and roller sleeves 16 fitted on both ends of the shaft 15.

[0028] like Figure 1 and Figure 7 As shown, the toothed cylinder 5 is mounted on the bracket 7 and located at one end of the horizontal track 1. The toothed cylinder 5 is the core component for realizing the winding and unfolding of the insulation cover chain. Its outer peripheral surface is provided with tooth grooves 20 as a transmission structure. The shape and size of the tooth grooves 20 match the roller sleeves 16 on the connecting shaft 4. When the toothed cylinder 5 rotates, the tooth grooves 20 can reliably mesh with the roller sleeves 16, thereby driving the entire insulation cover chain to move.

[0029] The curved track 8 smoothly connects the end of the horizontal track 1 to the lower periphery of the gear cylinder 5. When the wheel 13 on the intermediate insulation cover 3 transitions from horizontal movement to vertical winding, it rolls along the curved track 8, ensuring a smooth transition.

[0030] The gear cylinder transmission mechanism 6 is used to provide rotational power to the gear cylinder 5. For example... Figure 7 and Figure 8 As shown, the gear cylinder 5 includes a cylinder body 17 and a gear ring 18 fixed to one side of the cylinder body 17. The gear cylinder transmission mechanism 6 includes a second motor 21 and a drive gear 22. The drive gear 22 is mounted on the shaft extension of the second motor 21 and meshes with the gear ring 18 of the gear cylinder 5. When the second motor 21 is started, it drives the gear cylinder 5 to rotate through gear transmission.

[0031] The bracket 7 is used to stably fix the gear cylinder 5 and the gear cylinder transmission mechanism 6 in a predetermined position. The gear cylinder 5 is typically mounted on the bracket 7 via a bearing seat 19 to ensure smooth rotation.

[0032] The working process of this device is as follows: During unfolding (covering the steel billet): The gear cylinder transmission mechanism 6 drives the gear cylinder 5 to rotate in the first direction (e.g., the opposite direction). The toothed grooves 20 on the gear cylinder 5 push the roller sleeves 16 on the connecting shaft 4, unfolding the intermediate insulation covers 3 wound on the cylinder body 17 one by one. The wheels 13 of the intermediate insulation covers 3 roll down along the arc track 8 and transition to the horizontal track 1, thereby pushing the entire insulation cover chain (including the trolley insulation cover 2) forward along the horizontal track 1 until it covers the steel billet of the target length.

[0033] Retraction process (exposing the steel billet): The gear cylinder transmission mechanism 6 drives the gear cylinder 5 to rotate in the opposite second direction (e.g., forward), the tooth groove 20 meshes with the rolling sleeve 16, and pulls the insulation cover chain back one by one. The wheels 13 of the middle insulation cover 3 move along the horizontal track 1 and roll upward via the arc track 8, and finally tightly wrap around the cylinder body 17 of the gear cylinder 5, completing the storage.

[0034] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself. Various changes in form and detail may be made to the present invention without departing from the spirit and scope of the appended claims.
