The second control valve 405 is fixedly installed on the second water pipe 404.

[0027] Furthermore, the two ends of the third water pipe 406 are fixedly connected to the first water pipe 402 and the first nozzle 407 respectively, and the two ends of the fourth water pipe 408 are fixedly connected to the second water pipe 404 and the second nozzle 409 respectively.

The top of the water collecting frame 6 is fixedly connected to four connecting frames 7, and one side of the four connecting frames 7 is fixedly connected to the first nozzle 407 and the second nozzle 409 respectively.

[0028] Furthermore, a filter screen 9 is embedded in one side of the water collecting frame 6 , and the filter screen 9 is located on one side of the conduit 8 . The filter screen 9 filters the water in the water collecting frame 6 to prevent debris from entering the water tank 3 .

[0029] Furthermore, a feed assembly 2 is provided on the side of the continuous casting mechanism main body 1 away from the first nozzle 407. The feed assembly 2 includes a feed hopper 201, an inclined tube 202 and a first control valve 203. The two ends of the inclined tube 202 are fixedly connected to the feed hopper 201 and the continuous casting mechanism main body 1 respectively, and the first control valve 203 is fixedly installed on the inclined tube 202.

[0030] Among them, the molten steel is poured into the feed hopper 201, and the molten steel enters the continuous casting mechanism body 1 through the inclined tube 202.

At the same time, the outflow speed of the molten steel can be controlled by the first control valve 203 according to needs, and the first control valve 203 is closed. The molten steel in the feed hopper 201 cannot enter the continuous casting mechanism body 1 through the inclined tube 202. The structure is simple and easy to use.

[0031] The method of using this embodiment is:

[0032] During use, the steel plate is processed by the continuous casting mechanism body 1, the water pump 401 is started, the water pump 401 works to extract the water in the water tank 3, and injects it into the cooling box 403 through the first water pipe 402, thereby absorbing the heat inside the continuous casting mechanism body 1, and then preliminarily cooling the steel plate.

[0033] It is worth noting that the main body 1 of the continuous casting mechanism includes key components such as the intermediate tank, the crystallizer, and the dummy rod. The molten iron is first moved into the intermediate tank and then injected into the crystallizer through the water inlet from the intermediate tank. The core function of the crystallizer is to cool and solidify the liquid steel into a solid billet. The head of the solid billet formed in the crystallizer will first be caught by the dummy rod. As the dummy rod moves upward, the billet is gradually pulled out of the crystallizer.
