[0002] Rollers are an important part of the metal rolling process, squeezing metal sheets to deform them in order to improve their mechanical properties.

[0003] Quenching is an important step in the roller processing process. Induction heating of the roller by an induction coil can quench the roller continuously, which improves the quenching efficiency and reduces the quenching cost.

In order to solve the above problems, traditional induction equipment will install a protective structure on the outside of the equipment to prevent steam diffusion from affecting the visual environment and processing environment in the quenching workshop; however, the steam protection effect of the protective structure alone is limited, especially for large rollers, which have a long quenching time and a large amount of continuous steam. After a certain period of time, the protective structure will fail. In addition, it is difficult for traditional protective structures to collect and process the steam in a centralized manner, and it is difficult to efficiently recover the heat in the steam, resulting in a waste of resources.

[0025] See attached Figure 1 -Attached Figure 5 A continuous roller processing quenching equipment includes a first driving device 100 for controlling the rotation of a roller 300, an induction heating device 400, and a second driving device 200 for controlling the induction heating device 400 to move along the roller 300. The first driving device 100 can limit the roller 300 and control the roller 300 to rotate around itself in a vertical state; the second driving device 200 can control the induction heating device 400 to move along the axis of the roller 300 to achieve continuous heating of the surface of the roller 300, and cooperate with the water spray structure in the induction heating device 400 to achieve continuous quenching of the roller 300.

[0026] Specifically, the induction heating device 400 includes a mounting ring 410 for mounting an induction heating coil and a mounting plate 420 fixed to the lower end surface of the mounting ring 410. The mounting plate 420 is horizontally arranged and extends outward. A protective device 600 is provided at the bottom of the mounting plate 420 and is arranged in an annular manner on the outer side of the roller 300. A gap is formed between the protective device 600 and the roller 300 to form a protective chamber. An air supply device 800 is provided at the bottom of the protective device 600, and a negative pressure exhaust device 500 is provided at the top. Gas can be pumped into the protective chamber through the air supply device 800, and steam can be discharged from the top through the negative pressure exhaust device 500. The discharged steam is heat exchanged through the copper pipe to save resources. At the same time, by providing the protective device 600, the steam can be blocked and guided during the quenching process to avoid steam overflow, thereby improving the workshop environment for quenching the roller 300.

[0027] In summary, by designing the above structure, a relatively closed protective chamber can be formed on the outside of the roller 300 in the circumferential direction. During the quenching process of the roller 300, the steam can be blocked and guided, and discharged in a concentrated manner for heat exchange. While improving the environment of the roller 300 quenching workshop, it realizes full recovery of heat resources and improves economic benefits.

[0028] The first driving device 100 here includes a first electric guide rail 110, a first electric slider 120 slides on the side wall of the first electric guide rail 110, a first limiting assembly 130 is fixed to the bottom of the first electric slider 120, and a second limiting assembly 140 is arranged below the first limiting assembly 130. The first electric guide rail 110 can be used to control the first electric slider 120 to move up and down, change the distance between the first limiting assembly 130 and the second limiting assembly 140, and realize the adaptive clamping of the roller 300.

[0029] The second driving device 200 here includes a second electric guide rail 210, a second electric slider 220 and a mounting platform 230. The second electric guide rail 210 can control the position of the second electric slider 220, so that the mounting platform 230 can move along the axis direction of the rolling roller 300, thereby driving the induction heating device 400 to move along the axis direction of the rolling roller 300 to achieve continuous quenching of the rolling roller 300.

[0030] Specifically; the air supply device 800 includes a plurality of air supply openings installed on the side wall of the second limiting assembly 140, and an air supply duct connected to the plurality of air supply openings. The plurality of air supply openings here can be arranged in a circular tangential manner, and the air supply duct is connected to an external air supply device, which can form a reversing upward airflow in the protective device 600 to accelerate the directional discharge of steam.

[0031] Specifically, the negative pressure exhaust device 500 includes a negative pressure pipe fixed to the upper surface of the mounting plate 420. The first end of the negative pressure pipe is connected to an external negative pressure device, and the second end is connected to the protection chamber. The steam can be discharged from the top through the negative pressure pipe to achieve directional collection of steam. In conjunction with the serpentine heat exchange copper tube on the outside, the heat in the steam can be recovered, thereby reducing the amount of steam in the quenching workshop and realizing resource recovery.

[0032] Please refer to the attached Figure 5 ; The protective device 600 here includes a plurality of positioning sliders 620, and an annular positioning groove is opened at the bottom of the mounting plate 420. The upper end of the positioning slider 620 is slidably connected along the positioning groove, and a flexible protective cloth 610 is fixed to the lower end of the positioning slider 620. During the installation of the roller 300, the plurality of positioning sliders 620 are moved to one side of the cylinder. At this time, the protective cloth 610 is in a stored state, which is convenient for the installation and positioning of the roller 300; after the installation and positioning of the roller 300 is completed, the sliding positioning slider 620 moves toward the outside, and the bottom protective cloth 610 moves with the positioning slider 620 to realize the annular wrapping of the middle roller 300 and realize the circumferential closed setting.

[0033] A locking assembly is installed between two adjacent positioning sliders 620. The locking assembly here can be selected as a mechanical locking method, a bolt locking structure, or a magnetic or snap locking structure to ensure that the outer protective cloth 610 and the positioning slider 620 maintain a relatively stable position during continuous movement to prevent steam leakage from the connection.

[0034] A traction device 700 is also provided on the lower outer side of the protective device 600, and the bottom of the protective cloth 610 is pulled by the traction device 700. The traction device 700 at the bottom can pull the protective cloth 610 to keep the protective cloth 610 in a relatively taut state, so as to reduce the influence of internal steam evaporation, water cooling spraying, and pump air ventilation, and keep a certain distance between the protective cloth 610 and the roller 300 to ensure the integrity of the protective cloth 610.

[0035] As a preferred traction method, the traction device 700 here includes a traction box 710, and a traction roller is elastically rotatably connected inside the traction box 710. A torsion spring is installed at the rotation connection between the traction roller and the traction box 710. A traction rope 720 is wound around the surface of the traction roller. The end of the traction rope 720 is connected to the bottom of the protective cloth 610, and the end of the traction rope 720 is clamped and fixed to the protective cloth 610 by a clip; the traction device 700 here can be arranged in a ring shape into multiple groups to ensure that the circumferential force of the protective cloth 610 is relatively consistent.

[0036] At the same time, a counterweight block may be hung at the bottom of the protective cloth 610 . Under the action of the counterweight block, the protective cloth 610 can be kept taut, thereby ensuring that the shape of the protective cloth 610 is relatively stable.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
