[0002] A continuous casting machine is a device used to continuously produce metal castings. It is an important part of the casting process, used to continuously cast molten metal into billets or plates. The cooling system in the continuous casting machine can control the cooling rate of each section through segmented cooling, making the temperature distribution of the billet more uniform throughout the process, which is conducive to obtaining consistent grain size and organizational structure.

[0003] Existing continuous casting machines often cast different materials, including steel, iron, aluminum, copper, etc. However, different materials have different solidification characteristics and heat dissipation capabilities, and their cooling positions are different. However, most of the existing cooling devices are fixedly installed on the conveyor line after the crystallizer, and the cooling position cannot be adjusted. As a result, when producing castings of different materials, it is easy to affect the grain size and microstructure of the castings. Therefore, we propose a new type of continuous casting machine segmented cooling system. Utility Model Content

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a continuous casting machine segmented cooling system, comprising: a conveying mechanism, a moving mechanism and a cooling mechanism, the conveying mechanism comprises a conveying line, the moving mechanism comprises a moving plate and a guide rail, the number of the moving plate and the guide rail are both set to two, the two guide rails are respectively fixedly mounted on the left and right sides of the conveying line, two rollers are rollingly arranged on the tops of the two guide rails, a rack is fixedly mounted on the bottom of the guide rail, a connecting plate is fixedly mounted on the outer surface of one side of the moving plate, a motor is fixedly mounted on the outer surface of one side of the connecting plate, the output end of the motor slides through the outer surface of the connecting plate and extends to the other side, a gear is fixedly mounted on the output end of the motor, the gear is meshed with the rack, and the cooling mechanism comprises a sprayer and a water collecting tank.

[0006] Furthermore, slots are symmetrically opened on the tops of the two movable plates, and the rollers are rotatably arranged inside the slots via bearings.

[0007] Furthermore, a connecting frame is fixedly installed on the top of the two movable plates, and a mounting frame is fixedly installed between the tops of the two connecting frames.

[0010] Furthermore, the bottom of the water collecting pool is fixedly connected to a downpipe, and the bottom end of the downpipe is connected to a water cooling device.

[0011] Furthermore, a connecting pipe is fixedly connected between the water cooling device and the sprayer, and a water pump is provided on the outside of the connecting pipe.

The output end of the motor 209 is fixedly installed with a gear 210, which meshes with the rack 206. The cooling mechanism 3 includes a sprayer 301 and a water collecting tank 302. The tops of the two movable plates 203 are symmetrically penetrated with slots 204, and the rollers 207 are rotatably arranged inside the slots 204 through bearings. The tops of the two movable plates 203 are fixedly installed with connecting frames 202, and the mounting frame 201 is fixedly installed between the tops of the two connecting frames 202.
