[0028] like Figures 1-4 As shown, this embodiment proposes a cooling water spraying device for the fan-shaped section of a continuous casting machine. It includes a base plate 1, fixed frames 2, and guide rollers 3. There are two base plates 1 and four fixed frames 2, arranged in pairs. Each pair of fixed frames 2 is fixedly installed on two base plates 1. Several guide rollers 3 are rotatably installed between two sets of fixed frames 2. The device also includes an installation assembly, guide plates 4, a flow-guiding assembly, flow-guiding plates 5, and a spraying assembly. The installation assembly is installed on each set of fixed frames 2. Several guide plates 4 are arranged in two groups, both groups being mounted on the installation assembly. The installation assembly is used to install the guide plates 4 onto the fixed frames 2. Four flow-guiding assemblies are arranged in pairs, each group being mounted on one of the four fixed frames 2. Several flow-guiding plates 5 are arranged in two groups, each group being positioned between each set of flow-guiding assemblies. Two spraying assemblies are installed on the fixed frames 2.

[0029] A recycling box 7 is fixedly installed on both base plates 1, and the recycling box 7 is located below the guide plate 4. Water falling from the guide plate 4 can fall directly into the recycling box 7 below the guide plate 4, so that the water or coolant can be recycled and reused. The guide plate 5 is installed at an angle on the limit frame 202. When the spray bucket 307 located on the side of the spray pipe 305 sprays water on the side of the billet, most of the water can be sprayed onto the inclined guide plate 5, and the water falls onto the guide plate 4 through the inclined guide plate 5.

[0030] In this embodiment, reference Figure 2The installation components include an installation box 101, bolts 102, and a connecting bracket 103. Several installation boxes 101 are provided, and each pair of installation boxes 101 is a group. The side of the installation box 101 is provided with a sliding groove.

Several spray buckets 307 are provided, and several spray buckets 307 are connected to the water spray pipes 305.

[0036] If the gap between the several water pipes 305 and the several adjacent guide rollers 3 is located at the same horizontal position, the water source or the cooling liquid can be sprayed out through the gap between the guide rollers 3, so as to contact the moving billet.

[0037] In the embodiment, after the billet is preliminarily cooled in the crystallizer, the billet enters between the two guide rollers 3, the guide rollers 3 can drive the billet to move, then the inclined guide plate 4 is inserted into the sliding groove of the inclined mounting box 101 by holding the connecting frame 103, then the bolt 102 is screwed into the threaded holes of the mounting box 101 and the guide plate 4, so as to fix the guide plate 4, then one end of the limiting frame 202 is inserted into the fixed frame 2, so as to drive the drainage plate 5 to be placed between the two guide rollers 3 and close to the side surface of the guide rollers 3, then the fixed rod 6 is inserted into the limiting groove and the limiting hole of the limiting frame 202 and the mounting plate, so as to place the drainage plate 5 on the side surface of the fixed frame 2, when the billet passes, the water pump 302 is started, the water pump 302 drives the water source or the cooling liquid in the water storage tank 301 to enter into the water pipes 305 through the water suction pipe 303, the water outlet pipe 304 and the connecting pipe 306, and then the water source or the cooling liquid is sprayed out from the guide rollers 3 through the spray nozzles 307, so as to be sprayed on the billet to cool the billet, it should be noted that the several water pipes 305 are vertically placed, and the spray nozzles 307 on the water pipes 305 are arranged in five spray nozzles 307 and four spray nozzles 307 from top to bottom, the drainage plate 5 is installed on the side surface of the water pipes 305 of the five spray nozzles 307, so as to block the water source sprayed by the spray nozzles 307 on the side surface of the billet, make the water source fall on the guide plate 4 through the inclined drainage plate 5, and then fall into the bottom recovery tank 7 through the inclined guide plate 4 to be recovered, so as to avoid guiding the water source sprayed on the side surface of the billet out.

[0038] The above merely describes the preferred embodiments of the present application, but should not be used to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
