Description

Technical Field

[0001] The utility model relates to the technical field of laminar flow roller spray welding auxiliary devices, in particular to a moving walking and rotating device for laminar flow roller induction remelting. Background Art

[0002] The laminar cooling roller is one of the important equipment of the hot rolling laminar cooling system. It is located in the laminar cooling stage from the finishing rolling exit to the coiler, and is a transmission device for strip conveying. The working conditions of the laminar cooling roller are very harsh. During the working process, it must not only withstand the high-temperature wear of the high-temperature slab, but also require a certain high-temperature hardness to ensure the wear performance of the roller. It must also withstand alternating loads (hot and cold fatigue) and local pressure impact loads, and requires good bonding strength to avoid various surface defects and failure. The failure forms of the laminar cooling roller are mainly steel plate wear and corrosion of cooling water vapor. At present, the most commonly used protection method is to flame spray a layer of nickel-based alloy on the surface of the laminar roller to increase its life. Flame spray welding needs to be completed in two steps: powder spraying and remelting. Remelting was originally carried out by flame heating. A large amount of flammable gases such as acetylene and propylene are consumed in the process. In addition, the open combustion flame has large losses and high energy consumption. The workload of safety production management is large, and the working environment of workers is poor.

[0003] In recent years, with the development of electromagnetic induction heating technology, electromagnetic induction heating is applied to the remelting of the spray welding layer to replace flame heating remelting. While reducing energy consumption, it improves the working environment of workers, reduces carbon emissions and safety risks, and meets the needs of green factory construction. For electromagnetic induction heating remelting, if the electromagnetic induction heating coil is to move relative to the roller workpiece, a flexible cable must be used to connect the induction heating coil and the induction power supply. The required cable is long, which will cause a large power loss of the coil and increase energy consumption. In order to ensure the electromagnetic heating power, the electromagnetic induction heating coil needs to be connected to the induction power supply through a copper busbar, which makes the induction coil inconvenient to move. The remelting cannot be carried out in the manner of "the heating coil moves in a straight line and the roller only needs to rotate".

[0004] Therefore, it is necessary to design a special device to conveniently and quickly realize the linear movement of the heating ring during the electromagnetic induction heating remelting of the laminar roller spray welding layer, and the roller only needs to rotate. Utility Model Content

[0030] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the utility model. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0031] Unless otherwise specifically stated, the relative arrangement of the parts and steps described in these embodiments, numerical expressions and numerical values ​​do not limit the scope of the utility model. At the same time, it should be clear that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0032] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction.
