Description

Technical Field

[0001] The utility model belongs to the field of special-shaped steel production, and in particular relates to an online cooling device for a special-shaped rolling roller. Background Art

[0002] During the production process of hot-rolled special-shaped steel, the rolling temperature is relatively high, generally above 980°, and sufficient cooling water is required to cool the hole mold to increase the service life of the roller hole. Due to the irregularities of the hole profiles of the special-shaped materials at each pass (i.e., the various parts of the rollers of the special-shaped materials are uneven), in the prior art, the cooling water pipe is often simply wrapped with steel wire to fix it on the frame of the rolling mill to spray cool the rollers. However, since the cooling water cannot act evenly on the hole profile, the hole profile of the special-shaped roller is not cooled enough locally and cracks are generated, which not only reduces the service life of the hole profile, but also seriously affects the surface quality of the product. Therefore, it is urgently necessary to provide an online cooling device for special-shaped rollers to ensure that the cooling water of the cross-section of the hole profile of the special-shaped material is uniform and sufficient, effectively improve the problem of hole cracking, and thus ensure product quality.

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] In the description of the present invention, it should be understood that the terms "middle", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0027] In the present invention, unless otherwise clearly specified and limited, the terms "set", "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection; it can be a mechanical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] like Figures 1 to 3As shown, an online cooling device for a special-shaped roll comprises a fixed frame 1 and a main water pipe 2, the main water pipe is movably mounted on the fixed frame, a water inlet pipe 14 is connected to the main water pipe, and both ends of the main water pipe are closed structures, at least two branch water pipes are connected to the main water pipe, each branch water pipe is provided with a water valve switch 12, to realize the opening and closing of each branch water pipe and the independent control of the cooling water flow, and each branch water pipe can be selectively opened and closed according to actual needs, so as to save water resources and reduce production costs, each branch water pipe comprises a first pipe body 3, a telescopic pipe body 4 and a second pipe body 5 which are connected in sequence, and the second pipe body Cooling water can be sprayed onto the roller. The first tube body is connected to the main water pipe. An adjusting frame for realizing the telescopic function of the telescopic tube body is also connected between the first tube body and the second tube body. The two ends of the adjusting frame are respectively connected to connecting rings 7. The two connecting rings are respectively fixedly connected to the first tube body and the second tube body. The two ends of the telescopic tube body are detachably connected to the first tube body and the second tube body through clamps 11. The connection between the telescopic tube body and the first tube body and the second tube body is provided with sealing gaskets (not shown in the figure) to ensure its sealing performance. The telescopic tube body in this embodiment is a telescopic high-temperature resistant bellows. The utility model adjusts the length of the water distribution pipe to make the distance between the water outlet position of the water distribution pipe and each part of the roller consistent with the hole shape, thereby ensuring that the cooling water of the hole section of the special-shaped material is uniform and sufficient. Figure 4 and Figure 5 As shown, the adjustment frame includes a fixed rod 8 and a movable rod 9. The movable rod is provided with a strip slide groove 901 along its length direction. The strip slide groove is provided with an adjusting bolt 10 that cooperates with it. The adjusting bolt is threadedly connected to one end of the fixed rod close to the movable rod.

In this embodiment, there are two arc-shaped installation grooves, which are respectively located at the two ends of the fixing frame and are connected with the two ends of the main water pipe. When the two ends of the main water pipe are respectively embedded in the two arc-shaped installation grooves, the main water pipe is driven to rotate under the gravity of multiple water branch pipes. At this time, the limiting member conflicts with the lower end of the fixing frame to achieve the position fixation of the main water pipe and the water branch pipe. This installation method is easy to disassemble and convenient for later maintenance. The fixing frame is provided with a fixing slot 102 for connecting it to the rolling mill frame, and a locking screw 13 is provided on one side of the fixing slot. When in use, one of the support rods on the rolling mill frame is embedded in the fixing slot, and then the locking screw is screwed to lock it.

[0030] The method of using the utility model is as follows:
