Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to a continuous casting roller surfacing welding slag processing device. Background Art

[0002] In steel production, continuous casting rollers are mainly used to keep the steel billets solidified. Under the effects of mechanical stress, thermal fatigue and metal wear caused by long-term use, the roller surface is oxidized and peeled off, which can easily cause cracks and breakage, posing safety hazards and short service life. In the prior art, surfacing technology is usually used to repair continuous casting rollers.

[0003] During the cladding process, a large amount of welding slag and a large amount of residual welding auxiliary agent that has not been completely used will be generated, which needs to be cleaned up. The welding auxiliary flux can be reused and has collection value. The existing cladding machine welding slag treatment is generally manually cleaned. Since the temperature of the welding slag is very high when it just falls, it is difficult to operate manually. It can only be cleaned uniformly after cooling after the cladding is completed. The labor intensity is high, the work efficiency is low, and the cleaning is very inconvenient. At this time, the welding slag and the flux are mixed and solidified together, which is not easy to screen, further increasing the difficulty of manual cleaning, so it needs to be improved. Utility Model Content

[0004] Based on the above problems, the purpose of the utility model is to provide a continuous casting roller surfacing welding slag processing device, which is convenient for timely processing of the fallen welding slag and separating the flux in the welding slag so that the flux can be reused and the difficulty of manual processing can be reduced.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A continuous casting roller surfacing welding slag treatment device, comprising:

[0007] A recovery plate is arranged on the base of the continuous casting roller cladding machine and is located below the continuous casting roller to be processed, and is used to receive the fallen flux;

[0008] The screen frame is arranged in the recovery tray. The screen frame includes an inclined screen plate. The high end of the screen plate is located directly below the continuous casting roller. A number of screen holes are scattered on the screen plate. The screen plate is used to intercept the falling welding slag and the flux falling from the screen holes.

[0009] As an optional solution, the screen frame includes a frame for mounting the screen plate, and support feet are arranged at four corners of the frame. The four support feet are inserted into the recovery tray, and the support feet are against the side wall of the recovery tray.

[0010] As an optional solution, the frame is hollowed out, the sieve plate is laid on the frame, and the sieve plate is fixed to the frame by a pressure strip.

[0011] As an optional solution, the frame is provided with retaining edges which are higher than the lower end and the edges on both sides of the sieve plate.

[0012] As an optional solution, the inclination angle of the sieve plate is 15° to 30°.

[0013] As an optional solution, the recovery tray is placed directly on the base, and two limit bars are provided at the bottom of the recovery tray. The two limit bars are respectively abutted against the two side edges of the base, so that the recovery tray can translate along the base according to the welding position of the continuous casting roller.

[0014] The beneficial effects of the utility model are as follows: the continuous casting roller surfacing welding slag processing device arranges a recovery tray and a screen frame under the continuous casting roller, so that the fallen welding slag and flux pass through the sieve plate arranged obliquely on the screen frame, and the fine flux passes through the sieve holes of the sieve plate and directly falls into the recovery tray, while the agglomerated welding slag cannot pass through the sieve holes and is filtered out and slides along the sieve plate and accumulates together, thereby simply separating the flux from the welding slag, achieving the purpose of welding flux recovery, and facilitating manual later processing of welding slag.

[0020] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0021] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0023] In the description of this embodiment, the terms "upper", "lower", "left", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0024] See also Figures 1 to 3 As shown, the preferred embodiment provides a continuous casting roller surfacing welding slag processing device, including a recovery tray 1 and a screen frame 2, wherein the recovery tray 1 is arranged on the base 3 of the continuous casting roller surfacing machine and is located below the continuous casting roller 4 to be processed, and is used to receive the fallen flux; the screen frame 2 is arranged in the recovery tray 1, and the screen frame 2 includes an inclined sieve plate 21, and the high end of the sieve plate 21 is located directly below the continuous casting roller 4, and a plurality of sieve holes 22 are scattered on the sieve plate 21, and the sieve plate 21 is used to intercept the fallen welding slag, and the flux falls from the sieve holes 22.

[0025] Therefore, by arranging the recovery tray 1 and the screen frame 2 below the continuous casting roller 4, the fallen welding slag and flux pass through the sieve plate 21 inclined on the screen frame 2, and the fine flux passes through the sieve holes 22 of the sieve plate 21 and directly falls into the recovery tray 1, while the larger-sized welding slag or sintered blocks cannot pass through the sieve holes 22 and are filtered out and slide down the sieve plate 21 and accumulate together. Moreover, since the slag is screened as soon as it is formed and falls, it is easier to filter out the flux, thereby simply separating the flux from the welding slag, achieving the purpose of flux recovery, and facilitating the manual later treatment of the welding slag.

[0026] Specifically, the screen frame 2 includes a frame 23 for mounting the screen plate 21, and legs 24 are provided at the four corners of the frame 23. The four legs 24 are inserted into the recovery tray 1, and the legs 24 abut against the side wall of the recovery tray 1, thereby facilitating the combination and separation of the screen frame 2 and the recovery tray 1. The screen frame 2 can be stably placed when combined, and it is convenient to handle the flux and welding slag separately when separated.

[0027] Furthermore, the frame 23 is hollowed out, the sieve plate 21 is laid on the frame 23, and the sieve plate 21 is fixed to the frame 23 by the pressure strip 25. Since the temperature of the welding slag is very high, the sieve plate 21 is a consumable part and needs to be replaced regularly. The structure fixed by the pressure strip 25 is convenient for the installation and replacement of the sieve plate 21, and the size of the sieve hole 22 can also be continuously adjusted according to the screening effect.

[0028] In particular, the frame 23 is provided with retaining edges 26 which are higher than the lower end and both side edges of the sieve plate 21 so as to limit and collect the filtered welding slag.

[0029] Preferably, the inclination angle of the sieve plate 21 is 15° to 30°. At this angle, welding slag and flux that fall from the high end of the sieve plate 21 and do not pass through the sieve holes 22 can slide freely along the sieve plate 21 and be further screened during the sliding process.

[0030] In particular, the recovery tray 1 is directly placed on the base 3 without being fixed to the base 3. Two limit bars 11 are provided at the bottom of the recovery tray 1, and the two limit bars 11 are respectively abutted against the two side edges of the base 3, so that the recovery tray 1 can translate along the base 3 according to the welding position of the continuous casting roller 4, that is, follow the position of the welding gun 5 on the continuous casting roller cladding machine, thereby reducing the volume of the recovery tray 1 and the screen frame 2, and improving the utilization rate of the recovery tray 1 and the screen frame 2.

[0031] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
